Are you someone who always likes to 'have a go' at any project that presents itself? There is nothing wrong with an adventurous spirit and a desire to stretch yourself to see if you can achieve something new, but there must be limits to such behaviour. While there are plenty of things where determination and effort will help you succeed, there are also areas where you really do need training and experience to complete a task safely. One of these areas is electrical installation work. When you are working with electricity, the risks to life are too high to not use a competent professional.
What are the risks involved?
You might think that there is not much that can go wrong if you restrict yourself to basic power installation or electrical work, but that isn't the case. You might think that stripping back a few wires and connecting them to some terminals is simple, and you might be right, but can you be sure that you can do it right? What happens if you strip back too much insulation and leave the conductor exposed? What happens if you don't tighten the terminal block sufficiently and the wire works loose over time and connects with the metal casing? What happens if you use the wrong cable and it burns out after a few days? There are a lot of things that could potentially go wrong that you might not spot but that an experienced electrician will see instantly. An electrical fault caused by a poor power installation brings with it the possibility of an electric shock, fire, or even death.
What electrical work can you do?
The law says that you are free to undertake any electrical work that doesn't involve hard-wiring anything into the mains. You can certainly go and buy any electrical items that you want. You can arrange them and ensure that they fit in the place where you want to put them, but when it is time to connect them to your home electrical supply, you must call a licensed electrician to carry out the work. Any power installation, light switch replacement or ceiling fan fitting must be left to a professional who understands how to complete the work in compliance with the legal standards.
If you are not sure whether the work that you need to do counts as 'electrical work', it is always worth checking with a professional. It isn't worth the risk of potentially injuring someone or burning down your home.
