AFDDs and SPDs: Essential Protection for Modern Electrical Installations

Electrical safety is a top priority in today’s homes and commercial buildings. As the number of electrical devices continues to grow, so does the risk of electrical faults, particularly arc faults and surges. By integrating Arc Fault Detection Devices (AFDDs) and Surge Protection Devices (SPDs) into your system, you can enhance both safety and reliability. Let’s explore what AFDDs and SPDs are, their unique roles, and why they’re indispensable in modern installations.

What is an AFDD?

Arc Fault Detection Devices (AFDDs) are advanced safety devices that detect and interrupt dangerous electrical arcs. An arc fault is an unintended electrical discharge that can occur in damaged or faulty wiring, potentially causing a fire.

How Does an AFDD Work?

AFDDs monitor circuits for arc faults and disconnect power upon detecting a dangerous arc. This prevents potential fires from faulty wiring or loose connections.

Where Should AFDDs Be Used?

Do You Need an AFDD for Every Circuit?

Typically, AFDDs are installed on high-risk circuits. Since each AFDD protects only one circuit, you’ll need multiple AFDDs if you want protection across different areas. We recommend assessing which circuits in your property are most vulnerable to arc faults and consulting with a qualified electrician to decide where AFDDs would be most effective.

What is an SPD?

Surge Protection Devices (SPDs) prevent damage from power surges—sudden spikes in voltage that can harm devices and wiring. Surges can be caused by external sources, such as lightning, or by internal sources, like large appliances turning on or off.

How Does an SPD Work?

SPDs absorb excess voltage and divert it safely to the ground, protecting connected devices from harmful surges. Typically, one SPD installed at the main distribution board can safeguard all circuits within a property.

Types of SPDs

AFDDs vs. SPDs: Key Differences

Feature AFDD SPD
Primary Function Detects arc faults to prevent fires Diverts surge energy to prevent damage
Protection Scope Single circuit Entire board or individual devices
Common Use High-risk residential and commercial circuits Distribution boards in buildings and homes

Why AFDDs and SPDs are Essential for Electrical Safety

Incorporating AFDDs and SPDs into electrical systems is a proactive approach to safety. UK regulations, like BS 7671 (IET Wiring Regulations), highlight the importance of these devices, especially in high-risk areas. With AFDDs to mitigate fire risks from arc faults and SPDs to prevent equipment damage from voltage spikes, your property remains protected from the unexpected. Consider your building’s needs and consult a qualified electrician for installation advice.

Busting the myths
surrounding LED Lighting

LEDLighting  is leading the way in the electrical  lighting world for many reasons, but some are still weary of making the switch based on the negative reputation these light bulbs/lamps started out as having. There are many benefits to making the switch…

Warm white light
Create a warm, cosy
environment

Energy efficient
Longer lifetime & uses 90%less energy than regular bulbs/lamps

Quality light
Perfect lighting, instantly with no warm-up time

Dimmable light
Even works with dimmer switches to create the perfect mood

To help you reap the benefits of LED lighting, we thought we would bust a few of the myths surrounding this advance in environment technology…

LEDs are dull and
not bright enough

A 7W LED bulb shines the same amount of light as a 60W traditional bulb or a 12W energy saving bulb. There are both warm, yellow tone lights (the same colour of light from traditional bulbs), or go for a whiter light (that is closer to natural light).

LED bulbs take time to warm up and reach their full levels of light

LED bulbs/lamps do last longer than the non-LED bulbs but do not unfortunately last forever

LED Bulbs don’t
get hot

LED bulbs emit some heat but not as much as other bulbs. LED bulbs don’t give off infrared which means less energy is wasted via the creation of heat within the bulb. Infrared doesn’t add anything to the brightness of the bulb.

LED bulbs/lamps last forever

LED bulbs/lamps do lastlonger than the non-LED bulbs but  do not unfortunately last forever

Switching to LED
bulbs costs more

The initial cost of an LED bulb is more than traditional bulbs, however because LED bulbs have a longer lifespan you are going to save more money in the long-term thanks to not having to purchase replacement bulbs as often. The running costs of LED bulbs is also much less so your energy bills will be less.

LED bulbs can not be controlled via a dimmer switch

The majority of LED bulbs can in-fact be controlled by a dimmer switch. Dimmable LED bulbs are digital which means they are either on or off, to create the effect of being ‘dimmed’ they rapidly switch between on and off faster than our eyes can see.

LED lights are so bright they are harmful to our eyes

This is not the case as the light in an LED bulb is emitted in a similar way to traditional bulbs, throughout the glass encasing, instead of via one single point of light (which could be damaging). The level of light emitted from an LED bulb can be brighter than traditional bulbs, but is still not as bright as natural light.

LED lighting shows advances in technologies, moving away from short-term non-environmentally friendly, and non-eco-friendly bulbs towards a better quality source of artificial light that focuses on the long term benefits.



The Most Dangerous Electrical Items in Your Home

We use them every day, but electrical household items always come with a certain amount of risk involved.

Usually that risk is very low, but some items are more dangerous than others.

Here’s a list of the most dangerous electrical items in your home.

d
1. Washing Machines

According to a Which? investigation that used a Freedom of Information request, 12,000 fires were caused by faulty products between 2011 and 2014.

At the very top of the list was a surprising offender: washing machines.

It turns out that 14 per cent of fires caused by electrical items were caused by these over a period of three years. And although it does not say why this is, it could be that many people leave their washing machines on when they are not at home, meaning if a fire starts they are less likely to be around to put it out.

2. Tumble Dryers, Dishwashers and Other Items

In the same Which? research, tumble dryers were also high on the list, leading to 12 per cent of fires. Next came dishwashers with 11 per cent (and dishwashers can also be dangerous if they become breeding grounds for bacteria and mould). Cookers came next with 9 per cent, and fridge-freezers were fifth with 7 per cent.

3. Extension
Cords

Extension cords are one of the most dangerous appliances in the home – and it is easy to see why. It is very easy to overload extension cords, and this can present a fire risk. Be very careful with your extension cords, and don’t use them if they look old and worn out.

4. Space
Heaters

Leaving a space heater alone is a very bad idea. Also be very careful where you position yours, and make sure it is not near to any fabric like the curtains or the carpet – and always turn it off when you go to sleep.

4. Stoves

Another obvious one, stoves create heat, and that means there is always a risk of fire occurring. Electric stoves can be especially problematic because when the stove is turned off, the colour may return to black even while the stove is still hot.

5. Adaptors

Adaptors are another simple but potentially dangerous device. The same Telegraph article states that 72 types of adaptors have been discovered to be faulty over the last four years.

d
6. Any
Faulty Products

Another obvious one, stoves create heat, and that means there is always a risk of fire occurring. Electric stoves can be especially problematic because The Telegraph reported on the topic of product recalls here, and that while four million defective  evices have been recalled in recent years, as many as 90 per cent of them remain in homes (it got its information from Electrical Safety First). You can check products on the faulty

product checker here, and always stop using anything that you find to be faulty.the stove is turned off, the colour may return to black even while the stove is still hot.

7. Other
Potentially Dangerous Items

Other household electrical items that could present a danger include clothes dryers, microwaves, toasters, hairdryers, humidifiers and more. In fact, any electrical items can potentially be dangerous, so it is important to take precautions when using them.

 

Always use them as they are designed to be used, and don’t leave them on overnight or when you go out. Also, be very  areful around children, and ensure children only use them when supervised.



Top Electrical Facts Every Homeowner Should Know

At some point in time every home owner has the dreaded issues with their electricals, whether this be faulty fuses, broken electrical appliances that trip the entire system, having to re-wire something, etc. The list is endless. To help you along your way when this inevitably happens we have compiled a list of tips to help you with the most common issues…

How to test a socket

Testing your socket to see if it is fit for purpose doesn’t mean just checking for voltage, it will need a visual inspection i.e. any cracks, any discolouring and that the wires are in the correct terminals. Then you need to check that all the terminals are tight to ensure you don’t have any loose connections. You can prove the socket works by plugging in a charger or appliance (if you don’t have a voltage indicator) but it is always better you use the voltage indicator if possible. Now all of the checks are done you just need to screw the socket back to the wall. Ensure you don’t trap any cable when pushing the socket back or nipping the conductors with the socket screw.

Replacing wall sockets

click here for switches & sockets

For replacing sockets you will need to ensure that the socket has been successfully isolated. To do this use a voltage indicator to see if the socket is live or dead, (if live, switch the power off to the socket at the consumer unit  once you have done this you need to prove the voltage indicator is working on a source which you know is working by testing a live socket. Now you are ready to remove the old socket and put the new one on. If you have enough slack on the conductor it is advised that you cut off the old exposed bit of cooper and re-strip the conductors. Then put the brown in the L terminal, the Blue in the N terminal and the Green/Yellow sleeve earth conductors in the E terminal along with a 3rd earth conductor to earth the back box if it is metal, especially if your socket has a metal front. Once you are sure all of the terminals are correct and tight you can turn the socket on and test it once you have screwed it back.

Checking and re-wiring a plug

click here for cables

Checking a plug is very similar to checking a socket, looking for any signs of something awry such as discolouration, cracks etc. Making sure it’s not plugged in, check the main cable going into the plug, has the covering come away? Is it loose? Then unscrew the backing, checking that the wires are correctly fitted. Make sure the main cable is secured in place with the coating going into the plug rather than there being a gap between the coating and plug casing.

How to reset the fuse box

Firstly, find the fusebox! It will contain 3 things,

1) the main switch which allows you to turn the electricity to your entire home on or off.

2) Residual Current Devices (RCD) these are switches that trip a circuit and instantly disconnect the electricity should something go wrong. 

3) Circuit breakers these are automatic protection devices that switch the circuit off if it detects a fault.

Simply find the fault – this is usually an item that has just been switched on, unplug this and reset the switch. Test the item/socket that tripped the system before trying it again.

How to check for wires before installing anything on your walls

click here for tools

Before you hang anything on your walls you need to know what is behind the wall. The safest way to do

this is to purchase a sensor (which are inexpensive) and scan the whole wall to track where everything is placed. Do not under any circumstances hang anything up without checking first.

Using adapters and extensions

Many households have adapters and extension cords in abundance. Using these correctly is simple, but

there are still things that can go wrong. Check that you are not overloading either, as this could trip the electrics, or worse, start a fire. Extensions that are overstretched or are plugged into cables that are overstretched can lead to broken wires, disconnected electricity or people falling over them. Never join two cables together by twisting the bare wire together to elongate an extension. Never use damaged extension leads or adapters, replace them immediately to avoid any risks.

Backup equipment

Every new homeowner should have a set of tools for all sorts of jobs. To cover your potential electrical issues, make sure you have the following in your home, just in case: a quality insulated screwdriver, a torch (just in case the electric trips out), spare light bulbs, a couple of spare sockets and extension leads.

New homeowners often have a learning curve period where they discover how to build the basic DIY skills. When it comes to electrical work the above is vital to know, however if you have a greater issue, have and issues or can’t figure out why your household electricity is having issues, call a qualified electrician, never try and attempt to fix the problem yourself if you

are unsure.


Many adults spend most of their time at work, in the office, but how can you make sure that this time is well spent and as productive as possible? Well, there are lots of ways you can enhance this that are inexpensive, easy to achieve and are long-lasting…

Depending on the purpose of your office; the design, layout etc. of your office should reflect this, for example a creative based business should focus on enhancing creativity, an analytical based company should look to provide a structured ‘focus inducing’ environment. Here are our top tips to suit both:

all offices

Tricky Temperatures
Whether it’s too hot, or too cold can have a direct impact on the productivity of your teams and the quality of work that is produced. This is difficult to monitor in open office environments meaning multiple heating or air conditioning units, or multiple controls are needed. This is much easier to manage in segmented offices. This is also easier to manage in summer when you can simply open the windows. Winter is more difficult as you may need additional heaters, Panel Heaters or Underfloor Heating are best for larger spaces, whilst Wall Fan Heaters are best for smaller rooms.

ergonomics
Sitting in an office environment at a desk for long periods of time can be hugely affected if the furniture you are using and the seating you are sitting on are not adjusted, well made, sturdy and long lasting. Sitting in uncomfortable positions, at low quality furniture can deplete your motivation, posture, cause physical issues and result in decreased productivity.

let there be light!
Lighting is a huge factor when it comes to productivity. Ensuring you have as much natural light as possible is step one. Step two is high quality, long lasting lights, or task specific lights, for example desk lamps that can be adjusted. LED lighting works perfectly for offices as its long lasting, bright and is energy efficient.

Accessibility to Connectivity
Today’s offices are full of gadgets, computers and various technologies, which can mean wiring, cables, extension cords, and an electrical nightmare, which someone usually falls over. Wiring and Cable Management and increased opportunities for connectivity using their various gadgets can help save time and increase productivity, think about the number of Electrical Sockets you have and how you can increase these.
Creative, Relaxed Environments:

colour me creative
The effects of colours on the human psyche, mood and levels of productivity have been vastly studied. Broadly speaking, blues, greens and related colours inspire creativity as they relax the mind, whilst reds and oranges help focus the mind.

community is key
Communal working spaces or ‘open-plan’ offices have many benefits for creative environments. Open plan allows cross communication between teams, idea generation, debating and much more.

Calm Among the Storm
Supplying sufficient, creative and ample storage is a must to keep work productive whilst staying creative. Clever and smart storage such as fold-away units or built-in discreet shelving helps keep organisation amongst the creative.
Analytical, Structured Environments:

Be a Part of the Patrician
Enclosed office spaces can produce quality work just as much as open plan offices. Partitioned areas for quiet work and small team work, work perfectly for logical thinking.

black & white
Simple contrasting colours can help with focusing and the colour red has been know to boost evaluative propensities and analytical natures. Whilst more ‘serious’ colours replicate the ‘seriousness’ of the work to be done.
Overall an environment that is tailored to the purpose of the company, or department, produces the best results, from the general layout of a room to the colour scheme, the style of furniture used, and the lighting in each room, tweaking these aspects can have a substantial impact on your team.


British Standard BS 7671 is the IET Wiring Regulations, which is the UK’s national standard for
electrical installation and wiring safety in buildings. The 17th edition was released in 2008, and it has been amended three times since then. The latest is Amendment 3, which was introduced in January 2015.

Why the latest changes? It was found that substandard connections by electricians have led to overheating resulting in a number of fires, and this led to proposals for changes to the regulations.

January 1 2015

This is the day that Amendment 3 became effective.

A six month transition period followed for contractors to prepare.

July 1 2015

All installations designed after this date have to comply with the new regulations.

January 1 2016

Regulation 421.1.201 comes into effect in full.

A number of changes have been made in Amendment 3,
and here is a summary of some of the most important to keep in mind.

Firstly, changes have been made to the Definitions in Part 2. These have been modified, and they have been expanded upon in places with new abbreviations added. A key difference is that the ‘competent person’ definition has been changed to ‘skilled person’ and ‘instructed person’.

Chapter 41 relates to protection from electric shocks, and RCD protection is now required for socket-outlets that are up to 20A. This is for all installations, with only a few exceptions.

Chapter 42 has seen a few changes in the area of protection from thermal effects. Regulation 421.1.201 has now been added, and consumer units must now have enclosures made from non-combustible material.

Chapter 52 covers selecting and erecting wiring systems, and regulation 521.11.201 has now been included. This details new requirements for the support methods for wiring systems. Also, the regulations for selecting and erecting wiring systems have been redrafted.

Chapter 55 has added a new section on 557 Auxiliary Circuits.

Section 559 now has changes for lighting installations outdoors, with new sections 714 and 715 specifically covering this.

Part 7 covers special installations or locations, and Section 701 covers locations with a bath or shower. RCD protection must now be provided for low voltage circuits.

In Appendix 6, the schedule of inspections has been replaced and there are a small number of changes to the Electrical Installation Condition Report.

Finally, one of the most important changes is the new numbering system, where regulations with
a .200 number are now specific to the United Kingdom.

This summary does not cover everything in Amendment 3, but simply provides an overview of the main changes. Use this as a basic guide, but make sure you have a full
understanding of Amendment 3 because you will be required to do so at your assessment visit.

20 Best Appliances And Gadgets Of The Last 100 Years

Since the early part of the 20th century, mankind has made great leaps in the world of technology.
In the home and office, the progress of technology has brought us a long list of appliances and gadgets that have helped to make our lives easier and more productive.

Here is a list of the 20 best appliances and gadgets we have seen introduced over the last 100 years. If you are like most people living in industrialised nations, you have probably seen or used all of them at one point.

An American inventor named Fred Wolf first introduced the domestic refrigerator in 1913. Mr Wolf’s invention combined the conventional icebox with compressor technology that had been invented several decades earlier. His design was improved by engineer Nathaniel Wales one year later, setting the stage for an appliance that would eventually become the tried and trusted Kelvinator. The domestic refrigerator made it possible to keep food cold for weeks on end rather than the few days allowed by the icebox. Our kitchens haven’t been the same since.

The electric cooker (stove) is actually more than 100 years old, but it did not really take off as a household appliance during its early years of development, mainly because the cost of electricity was so high. However, in 1905 an electrical engineer from Australia, David Smith, patented a new electric cooker that borrowed heavily from its high-cost predecessor. This new cooker used less electricity and provided a more even cooking surface by using heating elements and reflector plates. His original design from 1905 is still the basis for modern electric cookers today.

Air conditioning units of all sizes help to keep our buildings cool during the hot summer months. Although various forms of cooling technology have been in use for thousands of years, the modern air conditioner was not introduced until 1902. A little more than 100 years ago, Buffalo, New York’s William Carrier began working on what would become the first electromechanical cooling system in the world. Carrier’s device not only lowered the temperature of ambient air, it also controlled humidity. The company that bears his name is now a world leader in air conditioning development.

The rotary dial telephone is another device that did not gain wide acceptance when first invented sometime around 1904. Nevertheless, when AT&T decided to replace manual phone operators with automated switching, the rotary dial was there to facilitate the change. With the rotary dial, customers could make phone calls to whomever they wanted, whenever they wanted, without having to wait for an operator. The rotary dial telephone remained the worldwide standard until push button systems were introduced in the late 60s and 70s.

Coffee is one of the most consumed hot beverages in the world. Prior to the introduction of the electric coffee brewer in 1930, a patented invention of Chicago’s Inez Pierce, people would make coffee by boiling water on the stove or an open fire and then pouring it through ground coffee. Pierce’s invention incorporated an older vacuum brewer design with some of the same internal elements used on the electric stove to create the first coffee brewing system that did not require an open flame or stove surface. Making coffee was instantly more convenient.

There is much debate over who invented the first electric washing machine at the turn of the 20th century, due to conflicting patents. At any rate, the 1930s witnessed this new home appliance quickly becoming the standard in every middle-class home. The Great Depression and World War II slowed production of the appliances, giving inventors more time to improve existing technology. By the late 40s and 50s, there were several manufacturers competing to create the best automatic washing machine that could be turned on and ignored. Names such as General Electric (GE) and Bendix dominated the market.

Having an electric washing machine created the need for the electric clothes dryer. American inventor J Ross Moore invented and patented the first electric clothes dryer in 1938, having combined the manually cranked appliance invented in the 1800s by French inventor M. Ponchon with the electric motor used in the washing machine. A few years later, industrial designer Brooks Stevens came up with the electric clothes dryer featuring a glass window and a few other creative features. Laundry was made easier than ever with the washing machine and dryer side-by-side.

The world can thank England’s Hubert Cecil Booth for the invention of the electric vacuum cleaner in 1901. His first device was actually powered by an internal combustion engine, but it proved too bulky and unwieldy to be practical. After modifying his vacuum cleaner to use an electric motor, he was able to reduce both size and weight. Unfortunately, the British did not warm to the electric vacuum cleaner as quickly as America. Thanks to America’s adoption of Booth’s idea, the electric vacuum cleaner finally took off somewhere around 1913.

The first electric typewriter was as important to the office as the printing press was to mass printing. Despite dozens of mechanical typewriter inventions dating back to the 1700s, it was not until the electric typewriter introduced by IBM in the 1940s that users could produce a clean, crisp page that very closely resembled professional printing. IBM’s design also introduced proportional spacing to give a more even and consistent look across an entire page of text. Best of all, the electric typewriter did not wear out the secretary as quickly!

The domestic radio families used to gather around to listen to their favourite broadcasts dates back to the post-World War I era of the 1920s and early 30s. Unfortunately, no one knows who invented the technology. What became commercial radio broadcasting started as military broadcasting to aid communications among the Allies in the First World War. Companies such as Bakelite and Fisher began making domestic radios even as the pioneers of commercial broadcasting started going on the air in the late 1920s. Having said that, domestic radio gave birth to mass media all over the world.

Radio’s popularity as a means of mass communication among consumers remained strong until television broadcasters worked out all the bugs in their medium. The first ‘motion picture’ televisions were introduced by competing American and Scottish inventors in 1925, albeit crude devices they were. Nevertheless, that did not stop the first television station from beginning broadcasting in 1928. Through the 1930s and 40s, TV broadcasting remained largely the domain of universities and research institutes, but by the mid-1950s, television was on its way to replacing domestic radio. Today it continues to be one of the most important means of mass communication.

Few people realise the telephone answering machine dates back to the 1930s. When this device was introduced, there was no need for it on a large scale because residential telephone service was still going through its own growing pains. Nonetheless, in 1960, Japanese inventor Dr Kazuo Hashimoto came up with the Ansafone – the first commercially successful telephone answering machine in the world. Hashimoto continued to develop new machines in successive years, eventually becoming the first patent holder for a digital electronic answering machine in 1983. Thanks to Dr Hashimoto, we never have to miss another call.

We could not talk about the best appliances and gadgets of the last hundred years without mentioning the personal computer. Perhaps no other invention has done more to advance global technology. The first commercial device came out of Italy by way of the Olivetti company in 1962. Space exploration in the US and the Soviet Union pushed the personal computer forward and into the 1970s, eventually giving way to computer powerhouses like IBM and Apple. By the late 1990s, most middle-class homes in the West had at least one computer.

The hand-held remote control owes its birth to Serbian inventor Nikola Tesla, who patented his radio wave-based device in 1890. He was followed by Spanish engineer Leonardo Torres y Quevedo and his patented device in 1903. The work of both inventors eventually led to the infrared remote control we now use to operate everything from televisions to sound systems. Today’s remote controls are more likely to be based on infrared or Bluetooth technology, thanks to the work of companies such as ITT and Viewstar.

When laser disc technology was invented in the 1960s, it was originally intended for data purposes only. In the 1970s, Philips and Sony both began working on audio applications to replace the vinyl record. Phillips gave up shortly after embarking on the project, paving the way for Sony to create both the digital audio disc and the CD player necessary to use it. It was a dark day for vinyl and magnetic tape, eventually leading to the demise of both by the end of the 1980s. Sony’s success also laid the groundwork for the DVDs and Blu-ray discs we know today.

If you are old enough to remember the first commercially available microwave ovens, you may remember how frightened people were of potentially radioactive food. In reality, the microwave was not radioactive at all. It was simply a commercial application of radar technology used by the military during World War II. Tappan introduced the first commercial microwave in 1955, but its size and cost made it impractical. Amana came to the rescue in 1967 with a model that was ideal for home use. Over the years, the microwave has made the kitchen much more efficient and accessible.

The invention of the digital camera opened up photography to the masses by making it more affordable to take pictures. Prior to its introduction, film-based photography was limited only to those who could afford the cost of cameras and film. Eastman Kodak offered the first electronic camera using an image sensor in 1975. Although it was primarily a military product, it paved the way for mass production of digital cameras by the late 1980s and 1990s. By 2000, the digital camera had all but replaced film-based photography.

Putting the power of the personal computer in the palm of the hand was the impetus behind the development of the PDA. Pison released the first commercial PDA with the Organizer in 1984. Apple and IBM followed closely behind with their own competing devices, setting up a technology war that would eventually lead to the development of the smartphone. As for the PDA, it introduced the idea of portable information to business executives, sales managers, political leaders, celebrities and even the average consumer on the street. If it were not for the PDA, we probably would not have the modern smartphone.

If the personal computer is the most important invention of the 20th century, the mobile phone is not far behind. Mobile phones came to market in the early 1970s thanks to Motorola’s first hand-held phone device introduced in 1973. Their success prompted NTT to begin operating the first cellular system in 1979, followed closely by the Nordic Mobile Telephone system in 1981. The truly revolutionary technology that made all of this work meant that worldwide communications were soon to be in the hands of average consumers.

This is such a great list, how do we finish it? We chose to talk about the smartphone, which is actually a marriage between the PDA and the mobile phone. Even though hand-held computing and telephony were being combined in research laboratories in the 1970s, the first commercially available smartphone did not hit the market until the 1990s. When Symbian-powered devices from companies such as Qualcomm and Ericsson came onto the market, they changed everything. The smartphone is now easily one of the most important gadgets in the world.

And there you have it – our list of the 20 best appliances and gadgets over the last 100 years. It’s amazing how far we have come in such a short amount of time. Long live innovation!

Replacing a light switch in your home can be relatively easy if you have a basic understanding of electricity and you can use simple hand tools. With that in mind, the work can also be dangerous if you do not do it correctly; you should always seek the advice of a competent person before beginning a project such as this.

We have put together a step-by-step guide to walk you through the process. The Electrical Safety Council offers a free video on their website that you can use in conjunction with this guide.

Before getting into the step-by-step process, it is important to first identify the kind of light switch you have. Whether you are talking about a standard switch or one with a dimmer, there are three primary options used in the UK:

Which Switch do you have?

A one-way switch controls a light from a single location only. It is the simplest type of switch to change.

The two-way switch allows for control from two seperate locations. In most cases, two-way switches are mounted at each entrance to a given area.

An intermediate switch is used with two-way switches to allow for light control from three or more locations. Sometimes these are known as three-way switches. They are the most difficult to work with.

It is best to replace your current switch with the same kind. If you do want to upgrade from a one-way switch to either a two-way or intermediate, additional wiring will be required. The following step-by-step process assumes you will be replacing your current switch with a new one of the same type.

Step 1 - Turn off the power

The first step in replacing light switches is to turn off the power. This is easily accomplished by turning on the light in question if possible, then flipping off your fuse switches individually at the consumer unit until the light goes out.

If you are unable to identify the correct fuse at the fuse box, or for peace of mind, you can always turn off the main fuse switch. This will cut all power in the property, so ensure that you have enough daylight to complete the task. Once the power is off you can remove the light switch plate.

Step 2 - Identify the Wiring

With the power off and the faceplate removed, use a meter to test that the power is indeed cut. Before doing this, the voltage indicator first needs to be proven to work on a known live source to ensure that it is working correctly.

Even if all power in the property has been turned off, the light switch should still be tested. Once you have confirmed there is no power to the switch, unscrew it and slowly pull it away from the electrical box so that you can clearly see and identify the wiring pattern.

Do not remove any wires yet, Instead, write down the connectiojn pattern so that you can replicate it on the new switch.

Step 3 - Remove The Old Switch

After marking down the wiring pattern, you are free to remove the old siwtch. it is helpful to manoeuvre the wires so that they remain in the same relative position. This will make it easier to connect the new switch.

Step 4 - Install The New Switch

Now it is time to install the new light switch. Your new switch should either have screws or pinch sockets to attach the wiring. If it has both, you can choose whichever works for you.

Ensure that the cables are tightly connected in the terminal, but not too tight that you go too far through the conductor. Give each core a gentle tug once connected to ensure that the connection is secure. Once your wires are successfully connected, gently guide the switch back into the box and screw it down tightly

Please note that if your system has no earth grounding wire, you CANNOT use a metal switch. Doing so will risk electrocution.

Step 5 - Replace The Switch Plate

The last step is to replace the switch plate and turn the power back on. Some people will reverse the order just to make sure the switch is working befopre the switch plate is put back on. We recommend you do not do this. It only takes a few seconds to apply the switch plate and, if necessary, remove it again.

As you can see, with a little know how and the right tools, replacing a light switch at home can be a relatively straightforward procedure. Making it as easy as possible hinges on purchasing the right kind of switch to replace the one you are removing.

Howeverm it is only recommended to carry out this kind of job if you are fully confident in being able to complete the work safely. If you are not comfortable with the process, hire an experienced electrician to undertake the work or to check the work upon completion to ensure your safety.

10 Easy Ways To Reduce Energy Costs At Home | Yourelectrics.com

Reducing energy consumption in the home is one of the best ways to save money on household costs. A few small changes can have a big impact on the size of your bills. And what’s more, reduced energy consumption is kinder to the environment.

 

Saving energy is not difficult if you are willing to do a few little things that add up to a lot. Here is our list of 10 easy ways that you can reduce your energy costs at home:
10 Easy Ways To Reduce Energy Costs At Home | Yourelectrics.com

Install Insulation

Insulation in the loft and walls keeps cold air out during the winter and warm air out during the summer. It also helps to maintain more constant temperatures indoors. The Energy Saving Trust estimates that you can save as much as £140 a year by insulating the loft or £15 by topping off existing installation. Adding insulation to your walls could save as much as £160 a year. Both treatments will pay for themselves in just a couple of years; they will also make your home more comfortable and valuable if you choose to sell it.

Install LED Lighting | Yourelectrics.com

Install LED Lighting

Updating any traditional lighting in your home to LED alternatives can provide a significant reduction in energy consumption. LED lighting provides just as much illumination without using nearly as much power and is particularly efficient when combined with smart controls. Switching to LED lighting could save an average home around £230 per year in energy costs according to Comparethemarket.com. Bulbs also last significantly longer than conventional filament bulbs and are cool to the touch making them safer, especially for children.

Use Heat From The Oven

It might not seem like much, but we let an awful lot of heat escape after cooking. Rather than turning off the appliance and using an extractor fan to get rid of the heat, open your oven door and allow the heat to escape into your home. You might be surprised by just how warm your house can stay by using this excess heat. Obviously, this tip is only useful during the colder months when your boiler is on.

Pack the Fridge and Freezer

When the fridge and freezer are full, there is less air to keep cool. This makes for more efficient units that use less energy. You might consider scheduling weekly or biweekly trips to the supermarket in order to maintain the fridge and freezer packed for as long as possible. That’s not to say you should waste food to save energy because that is not good either. Nonetheless, loading them up and then slowly using the food over two weeks is more energy-efficient than making multiple trips to the shops every couple of days.

Use The Dishwasher Wiseley

A dishwasher is a great appliance that saves time and water. However, to get the most savings, it needs to be used wisely. Do not pre-rinse your dishes prior to putting them in the dishwasher – as long as the appliance is capable of still getting the dishes clean. Instead, just scrape the waste into the bin and load. You can save more money by skipping the heat-based dry cycle. Open the dishwasher door and allow the dishes to air-dry instead.

 Use The Dishwasher Wisely | Yourelectrics.com
Clothing: Wash Full Loads | Yourelectrics.com

Clothing: Wash Full Loads

Instead of washing multiple small loads of laundry every day, wait several days until you have enough for a full load. If you use an electric clothes dryer, doing larger loads on the same day saves money here as well. The second and third loads in the dryer will have the advantage of residual heat from the loads before. Better yet, drying your clothes on a line saves even more energy. Hang clothes outdoors during the summer and in the utility space during the winter.safer, especially for children.

Low-Pressure Shower Heads

High-pressure showerheads may feel good on the back and shoulders, but it also uses a lot more water. uSwitch.com says high-pressure power showers can use more water than a bath in some cases. For maximum savings, get a low-flow showerhead and learn to take quick showers. The Energy Saving Trust says you might be able to get an extremely efficient showerhead free of charge from your water company. They estimate that the average family of four could save more than £160 per year with an energy-efficient showerhead.

Adjust The Thermostat | Yourelectrics.com

Adjust The Thermostat

The good people at uSwitch.com explain that turning down your thermostat by just 1° during the winter could save as much as £60 per year on heating costs. uSwitch also says to avoid significant temperature swings when you programme the thermostat. Keeping a more consistent temperature at a lower level uses less energy than continually heating up and cooling down.

Sun and Shade

Learning how to take advantage of sunlight and shade can go a long way toward saving on heating bills. In the winter, use the bright sunlight from mid-morning to late afternoon to heat your home – just by opening the blinds and curtains. Keep those same blinds and curtains closed during the summer months to reduce heat build-up in interior spaces. Controlling the amount of sunlight that enters your home makes it easier to control your thermostat.

Look at Renewables | Yourelectrics.com

Look at Renewables

If you own your home and have a little money to spend, you might consider looking at some renewable strategies. Photovoltaic solar systems can generate electricity while solar thermal uses the sun’s rays to produce space heat and hot water. Both are great ways to supplement the energy you purchase from the grid. Along the same lines, look for energy-efficient models when it is time to replace appliances and your boiler.

Electrical Safety in the Home: What You Need to Know

Harnessing and generating electricity are two of the most
important technological advancements of the modern era.
Without electricity, our lives would be substantially different.
Yet as important as it is, electricity should never be taken for
granted. It is a dangerous commodity that could cause serious
injury or death if not treated with the proper respect.

In the home, owners or tenants often carry out electrical work themselves as a means of saving money. This is not always the best idea. Unless the consumer knows exactly what he/she is doing, a certified professional electrician should be used.

What the Law Says

Electrical installation in the UK is regulated differently, depending on
where you live. In England and Wales, it is governed by Part P
of the Building Regulations. The Building Standards system
is used in Scotland while Northern Ireland has no
specific regulations in place.

Part P

Part P of the building regulations means that anyone who is carrying out electrical installation or rewiring work must make sure that the work is implemented safely and offers protection from electrical shocks, fires and causes of injury.

The Government updated Part P for England and Wales in 2013, removing some outdoor and kitchen work from the list of work that is notifiable. This means it can be carried out as a DIY project without any official approval or signing off. Having said that, homeowners in England, Wales, and Scotland should always check with local authorities prior to embarking on any electrical projects. The local authorities will know whether the scheduled work is notifiable or not.

Notifiable Work

Work that is notifiable must be either completed by a registered electrician or signed off on by an approved third-party organisation after a thorough inspection. Failing to have notifiable work completed in this manner is illegal and it could subject homeowners to significant penalties. Other than some minor jobs, all work must be carried out by a registered electrician.

Employing a Registered Electrician

If you are a home owner, using a registered electrician to carry out electrical work in your property will mean that the job will be completed safely and comply with all relevant regulations. You’ll receive an Electrical Installation Certificate and a Building Regulations Compliance Certificate to demonstrate that the work is safe and meets all legal requirements.

What the Risks Are

The risks associated with carrying out electrical work are significant. First is the risk of serious injury or death resulting from accidents that occur during the installation process. As an example, a homeowner may not realise the importance of turning off power to the main fuse box prior to installing a new line. Failing to do so could result in electrocution.

Second, improperly installed electrical work has the potential of causing serious problems in the future. Those problems include electrical fires, short-circuiting, damaged appliances and electronics, damaged fuse boxes, and electrocution. It only takes one mistake to cause serious trouble.

What to Look For

There are certain things homeowners and tenants can look for if they suspect electrical problems in their homes. Some of the more obvious signs include frayed cords, overloaded sockets, and poorly wired cords. However, there are more subtle things to consider; things that may suggest you might have an electrical problem where it cannot be seen.

Your home is wired in such a way that each separate line has a fuse that connects it to the main power within the consumer unit. The fuse is designed to trip in the event the line is overloaded. Tripping fuses should be a rare occurrence if everything in your home is as it should be. If you are routinely tripping fuses – i.e., several times a month – you should have your home checked by a registered electrician.

Also, pay attention to scorch marks on sockets as well as sockets and plugs that get hot. Both are signs of a potential short-circuit or line overload.

If you are buying or renting a property that has been extended, rewired or significantly refurbished recently, you should ask to see the relevant certificates to make sure all any electrical work has been carried out safely.

Electrical safety in the home should never be ignored. Always be safe with electricity in order to avoid devastating injuries, loss of life, and loss of property.

LED Lighting: a Guide to Using LEDs in Your Home

LEDs are growing in popularity, and now it is possible to use LED lighting throughout
the home for any purpose, rather than relying on other less eco-friendly options.

LEDs tend to be more expensive than traditional bulbs, but prices continue to fall. In
addition, the fact that they are long-lasting, and the energy savings that they can lead to, can
make them the most cost-effective option for lighting your home.

Types of LED Lighting

LED bulbs are available in a wide range of
styles, including standard bulbs, candle
bulbs, coloured bulbs and more, and they
also come in a range of temperatures. If
you want a warm light temperature for your
LEDs, you will probably want something
around the 2600 Kelvin mark – any higher
than this can lead to colder lighting.

You also need to think about the amount of
output produced by a bulb. You can do this
by comparing your new LEDs to traditional
bulbs and making a quick calculation. For
example, with a traditional bulb, 100w is
often considered a good level for the main
light in a room. With an LED light, you will
want something about 10% of this value to
generate the same amount of brightness, so
choose a 10w bulb. You can use this basic
calculation with any LED bulb if you are
unsure how bright it should be.

Where to Use LED Lighting in the Home

LEDs can essentially be used
anywhere in the home to replace
older bulbs. LEDs are a great
option for dimmable lights (unlike
CFLs), but just make sure you are
buying bulbs that are designed to
be dimmable. If you do buy
dimmable LEDs, you may need to
change your dimmer switch to one
that is LED compatible.

LEDs come in a wide range of fittings, so often
you can simply replace your old bulbs with LED
bulbs without any problem. You may want to take
your old bulb to the store with you so that you
know which type of fitting you need.

One thing to be aware of is that LEDs are
low-voltage, so you may need to make
sure they are compatible with your
system. This is something that you will
want to talk to an electrician about.

When you are ready to replace your bulbs, start by replacing the lights you
use the most, which will normally be the main overhead lights in a room, and
this is where the biggest savings will be made. You can then move onto the
smaller lamps and spotlights around your home. It is a good idea to buy one
bulb first and test it in the room, then you can buy more when you are happy
that you have made the right decision.

Key Benefits of LED Lights

Using LEDs can save you money over the years because
they use far less energy than alternative options, and they
use even less than CFLs. If you are still using traditional
bulbs in your home, the savings you can make by
switching to LEDs can be huge. And the great thing is that
switching your lighting is one of the easiest and most
effective ways to reduce your electricity bill.

While CFLs are still a good option for saving electricity, they are
not as efficient as LEDs. In addition, CFLs take time to warm up
so you don’t get the instant light that you do with LEDs.

One of the things that has put people off LEDs in the past
is the assumption that they have a cold light temperature.
However, they have come a long way and it is now
possible to get LEDs in a wide range of temperatures, so
you can enjoy a warmer light in your home similar to that
produced by traditional bulbs. LEDs also come in a wide
range of colours and fittings to make them a truly
versatile option.

Always Choose the Best Quality

Although LEDs have many advantages over other types of lighting, the quality always
varies. If you want your bulbs to last the longest amount of time possible and to
produce the best light in your home, it is well worth investing in the best quality bulbs
you can find. It may mean a larger initial investment, but you will be able to enjoy the
full benefits of LEDs as a result.
