For a breaker failure, the two breakers on the sides of the affected breaker open, along with a transfer trip to a remote breaker, to isolate the failed breaker and remove two bus sections from service. The cause of the tripping circuit breaker can be isolated simply by turning off all the other circuit breakers, resetting the main circuit breaker, and then turn on the other circuit breakers one at a time. When the circuit breaker has been turned which has a fault or direct short then the main circuit breaker will trip off again.

Circuit Breakers and Electrical Safety . Electrical safety always begins with turning a circuit breaker off before performing any electrical work on a circuit or device connected to it.

There can be several reasons that a circuit breaker won't reset. First we must look at the function of the circuit breaker. A circuit breaker is designed to limit the current on a circuit to the rated level (measured in amperage) for which it, and the circuit is designed to operate at.
