Circuit breakers

Circuit breakers
Circuit breakers are automatic protection devices fitted in the consumer
unit which switch off a circuit if there is a fault. Circuit breakers are
similar in size to fuseholders, but give more precise protection than
fuses. When they ‘trip’, you can simply reset the switch. However, you
first need to find and correct the fault.

any questions?
