The consumer unit or fuse board is the heart of the electrical system in your property, it controls the supply of power and provides protection, to both life and to the building’s electrical system itself.
Many modern consumer units incorporate technically advanced protective devices such as:
- RCD’s – for protection against electric shock
- Circuit breakers (CB’s) – for the protection of the cables and electrical devices
Circuit breakers are rated in amperes (A) and protect the conductors or wires in your property from being exposed to excessive amounts of electric current, overloading cables can cause them to overheat and in extreme cases lead to the risk of a fire occurring.
