Technician B is correct because when an overload occurs, a fuse or circuit breaker (protection device) will create an open circuit to protect the electrical system. Fuses do not automatically reset; they must be replaced if blown. Circuit breakers can be reset manually, but this is not an automatic process following repair of the overload cause.
