Abstract:
A circuit breaker comprising:a housing; separable contacts mounted in said housing; an operating mechanism for opening said separable contacts when actuated; trip means for actuating said trip mechanism in response to predetermined current conditions and including ground fault trip means for actuating said trip mechanism in response to a ground fault, and arc fault trip means for actuating said trip mechanism in response to an arc fault; test means including a ground fault test circuit having a ground fault test switch for testing said ground fault trip means, and an arc fault test circuit having an arc fault test switch for testing said arc fault means; and a common test actuator moveable to a first position for actuating said ground fault test switch, a second position for actuating said arc fault test switch and a neutral position in which neither said ground fault test switch nor said arc fault test switch is actuated.
