Circuit Protection
The national safety standard (British Standard 7671 - the IEE Wiring
Regulations) requires every circuit to be protected by a circuit breaker or
fuse which will automatically disconnect the circuit in the event of an overload
or fault (such as a short circuit), to prevent fire and electric shock. In
domestic premises, these devices are normally contained in the consumer unit (or
'fuse box'). The fault causing a circuit breaker is reset or the fuse
replaced. It is essential that a 'blown' fuse is replaced by one of the
correct rating - this rating should be clearly indicated on the fuse box.
