A ground fault circuit interrupting (GFCI) device includes a conventional circuit breaker equipped with a trip mechanism operable automatically to open the breaker contacts in response to overcurrent conditions. A GFCI module, responsive to ground leakage current, actuates a trip solenoid to open the breaker contacts via the trip mechanism in response to a ground fault. An indicator, carried by linkage interconnecting the solenoid and trip mechanism, is moved into registry with an opening in the breaker case only upon actuation of the solenoid to thus indicate the occurrence of a ground fault trip function.
