Electrical Service: Circuit Breakers or fuses?
Circuit breakers are typically selected over fuses because circuit breakers can be reset where fuses have to be replaced. The most time consuming activity that results from the operation of the overcurrent protective device is typically investigating the cause of the overcurrent condition. A known overload condition is the only situation that permits the immediate resetting or replacement of overcurrent protective devices per OSHA. Thus, if this device opens, it should not be reset or replaced without investigating the circuit since it most likely was a short-circuit condition
