Information About and Wiring

Until recently the standards and regulation surrounding the electrical wiring and installation in the UK varied greatly from other European countries. However the standards and regulations in the UK no longer differ substantially from other European countries.

The current wring colours used in the UK are as follows:

o Protective Earth = Green

o Neutral = Blue

o Single Phase: live, three phase L1 = Brown

o Three Phase L2 = Black

o Three Phase L3 = Grey

When it comes to the UK electrical power circuits, they are normally described as either radial or ring. If a power circuit is radial the power is transmitted from point to point, which is conducted by a single length of cable that links each point to the next. This starts at the main switch or fuse and terminates at the last connected device. It may branch at a connection point. Lighting circuits are normally wired in this way, but it may also be used for low power socket circuits.

The ring circuit however is unknown in many other national wiring codes. With a ring circuit a cable starts at the supply point and then goes down to each device, the same way as in a radial circuit. The last device is connected back to the supply so that the whole circuit forms a continuous ring. The primary advantage is to allow more power to be supplied than could otherwise be carried with a given size of cable.

Going back to the standards and regulations, it should also be noted that there has been considerable change to the rules surrounding . These changes mean that all electrical work within a domestic setting must be in compliance with British standards as a requirement of Part P. The building regulations, which are Part P, were introduced to England and Wales on 1st of January 2005.

When these building regulations were introduced in 2005 they were met with a lot of controversy especially when it come to the rules surrounding work that is carried out by non-professional bodies such as DIY work. Under the new regulations, initiation of any work other than simple changes becomes notifiable to the local building control authority. What is meant by simple changes are aspects such as adding extra lights or sockets to an existing circuit. Work on a bigger scale than this should be carried out by a professional.

When the new Part P regulations were brought about in 2005 the government approved several professional bodies’ awards to ‘competent persons.’ This allows these ‘competent persons’ to self-certify work they carry out.

The Building Control Authority must be informed of any work that is carried out by someone not qualified under this scheme, unless the work is done in an emergency.

Any electrical work carried out needs to be approved and when it is approved you will be granted a certificate, a Building Regulations Completion Certificate.

If you do have any electrical wiring or installation work that needs to be carried out on your property it is important that you hire a professional to not only make sure that your work is carried out in a professional manner but to ensure that your or re-wiring etc meets the standards set out by the Part P regulations.

3 Questions to Ask Your Electrical Installations Provider

Finding a reliable electrical installations company is of vital importance for those seeking to plan and install electronic solutions in a range of properties, including commercial buildings as well as private residences. As a reliable electrical system forms a base for the workings of many premises, quality is of vital importance.

Making this selection is not always so straightforward however, as there are many companies all offering their services and the clients is often highly unlikely to understand fully the specifics of the task that is being carried out. This can make it difficult to know whether the plan proposed is of quality and whether the service provider is reliable.

With this in mind, there are several questions that you can ask your electrical installations provider in order to determine whether they are the right choice for the installation in your residential property or your business premises; here are three of the most important ones.

Firstly, you will need to ask how much experience the service provider has in installations in your particular type of building and whether or not they have completed projects similar to yours. This is important for a number of reasons.

Different buildings have different qualities and different requirements, which is first and foremost the reason that prior experience delivering for a project similar to yours is important. An example of this would be in old or historic building, where regulations and restrictions need to be considered and certain structural aspects should be kept in mind.

One the other hand, a modern, new build residential property will have entirely different specifications and needs. Therefore, your first task should be to find out about the work previously done by the company and whether or not it aligns with the kind of work that you want doing on your behalf.

The second question that you absolutely must ask your electrical installations provider is what exactly is within their capabilities. This is important as ‘electrical solutions’ is an umbrella term that covers a wide range of different tasks and competencies. These can include rewires and additional circuits, periodic inspections and reports, fuse board changes and upgrades and much more.

Of course, knowing exactly what you require in advance is going to be beneficial too, as it will help you narrow down companies that offer the specific services that you are looking for. If you are unsure about the exact services that you require, the alternative is to ask the company for a full analysis of your needs and recommendations of the services that you need.

It is wise to obtain a few of these, allowing you to see what different services providers offer. You will then be well positioned to choose the one that offers the most relevant services that fit your specific needs.

Lastly, the third question you should ask your electrical installations provider is whether or not they offer a comprehensive support service for you during and after your . This can include aspects such as periodic testing and safety checks as well as an emergency call out helpline if you run into difficulties or notice a fault.

This is important, as one of the major concerns of people is that the company will wash their hands of responsibility of the project after installation. A reputable company will instead make sure that you have the technical support that you need during and after the completion of the project so that your investment was worth every penny.

These are just three of the questions you should ask your electrical installations provider before you begin working with them. These can help you make a good choice in terms of a supplier that is able to not only meet your needs but also provide a genuinely high quality service too.

Discover Safety Tips on Any Electrical Installations

It is a common thing for many homeowners to do these things themselves: replace the light bulbs, wrap open wires with electrical tape, and change electrical outlets. There is no problem with doing all these electrical tasks yourself even if you are not a professional. However, you need to make sure that whatever you do involving electricity, you always prioritize your safety.

Regular Electrical Inspection is a Must

Even if you are the best in do-it-yourself electrical installations, you cannot guarantee your safety, especially if your house have not had an electrical inspection in the last 40 years. According several studies, most fires caused by faulty electrical installations are the result of homeowners’ non-compliance to regular electrical inspections. If you are not sure when your home had its last electrical inspection, check the electrical panel. See if there is a sticker with a signature or initial and a date. That is the last time your house has undergone an electrical inspection. What if there is no sticker on the electrical panel? Use the age of your house as your point of reference.

Use Only the Right Electrical Materials

At first glance, working on a few DIY electrical installations seem easy enough. However, when you mess up with a live wire, you are going to appreciate how professional electricians risk their lives to do electrical tasks. That is, if you are still alive after that. Actually, the professionals do not “risk” their lives because they know the safety rules on electrical installations, such as using only the right electrical materials.

For instance, if you are working on an electrical wiring project, make sure you use the right wire and connect the right part of the wire to where it belongs. If not, either your device will not work or you will cause a major electrical problem like fire or electrocution. Similarly, a wrong choice of socket will not only affect how your computer or refrigerator works but also the safety of using these devices. That is why before you start any task, consult the manual for the particular electrical device you are working on. You will find in the manual the right number of socket, outlet, bolts, and wires that the device needs.

Always Turn Off the Power Supply

Wherever and whenever electricity is involved, it is better to be safe than sorry. Turn off your power supply when you are doing any electrical installations, no matter how minor they are. Even if you are not working with a damaged outlet or installing a new bulb, turning off the power supply is the best thing you can do to ensure your safety.

Check the Electrical Materials’ Safety

Just because a wire is brand new does not mean it is 100% safe. Make sure it is safe by checking any tear or wear on the wire. You do not want to be shocked, electrically, before you realize that your brand new wire has some rat bites. Checking is always important regardless of the electrical materials you are going to use for electrical installations.

If you are not sure you can do your electrical installations 100% safely, it is better to call a professional electrician and have him do the job. Of course, you will have to pay him for the job, but think of it as worthwhile investment — you do not have to worry about getting electrocuted and you can be sure the electrical installations are done properly and safely.
