Each cable carries an electrical current through your home and its appliances, and each cable has a voltage limit. Within each cable are ‘cores’ which are made up of copper wires, that is coated with insulated plastic and is colour coded for its purpose (neutral, live, earth). These cores are then wrapped together within the cable by another layer of tough, insulated plastic.

It’s important that the correct cables type and size are used, as if not it could cause an electrical fire. For example, if a cable has a max load of 100V and 300V is sent through it, it could burn out and spark a fire in your home.
