A lack of electrical safety in the home is as bad as a lack of gas safety, ok, it might not cause an explosion, but it can kill quicker than gas and start house fires that kill and destroy property. You may not get a warning that you are about to be electrocuted, and in many cases it's fatal, you might get more warning that an electrical fire is starting, but what if you're not in? Electrical safety is largely common sense, and yet still people get admitted to hospital on a daily basis with electricity related injuries. Using electricity in the home is not all about safety however, it's about using it effectively, efficiently and helping yourself when things happen before you call an electrician. Sonetimes, if the power goes off, it's easily resolved and you don't need the services of an electrician, saving you money and time. We have produced this guide to help you get the most from your electrical system, use it safely, effectively and monitor its condition, so that if and when the time comes that you do need the services of an electrician, you will be better informed about how your system is performing and able to describe your problems to bring about a speedy conclusion. We will update this guide over the next few weeks.
The RCD. You may have heard these mentioned if you've called an electrician out in the past, or you may be aware of the lack of one when you wanted your new kitchen. Either way, they are very important devices and a regulatory requirementin all homes now when new work is carried out. So what does it do? Well, the RCD, (residual current device), measures the current leaving the fuseboard on its journeyaround the house circuits. It then compares the value of current returning to the fuseboard when the journey is complete. If the two current values are the same, (within predefined limits), it is a happy device and remains switched on. But if the value returning is less than the value leaving, it will switch off. The reason it switches off is because it has detected a fault in the system which could cause an electric shock. It takes very littlecurrent to kill an adult, less to kill animals, and sothesedevicesaresettooperateatasafelevelbelowthis value.
