Consumer Units

What is a consumer unit?

A consumer unit or CU or CCU is a type of distribution board utilised generally in domestic and light commercial environments. Other names for a consumer unit are:

    - Fuse Board
    - Fuse Box
    - Split Load Consumer Unit
    - Switchboards
    - Distribution Board

A consumer unit houses the fuses/RCDs/MCBs which are utilised as a protective means of automatically disconecting final circuit supplies in the event of a fault. Furthermore, the consumer unit should also incorporate a means of complete isolation of the installation, typically a douple-pole isolator which will disconnect both the line and neutral conductors of a single phase supply.

See 'Protective Devices' for further information.
