Consumer Units / Fuse Boards

The heart of your properties electrical installation.

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 fabric of the building.

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

Circuit breakers are rated in amperes (A) and protect the wires in your property from being exposed to excessive amounts of current, which would cause the cables to overheat and lead to the potential risk of a fire occuring.

What is the difference between a consumer unit and a fuse board?:

Fuse board is the old name for the device that protects the electrical installation in your property, called fuse boards because they are installed with fuse wire that melts when exposed to excessive current (amperes).

Consumer unit is the modern development of the humble fuse board. They are fitted with MCB’s, a type of switch that trips (switches off), when excessive current flows through the device. They can also be fitted with RCD’s and RCBO’s, devices that can trip if someone is receiving an electric shock.
