ABSTRACT:
A ground fault circuit interrupter (GFCI) circuit breaker test circuit for use with panelboards uses a selector switch, normally open switch, and a resistor to simulate a fault condition at the load output node of any one of several GFCI circuit breakers. This arrangement allows for testing of the circuit breakers while eliminating the need to use an external test actuator to operate the manual test button of each circuit breaker. Thus, shaft penetrations through the panelboard enclosure are minimized, resulting in reduced hazards, increased reliability, easier testing, and greater economy.
