Abstract: The present invention is directed to a protective device including a fault protection circuit configured to provide a fault detection stimulus in response to detecting at least one type of predetermined fault condition. A circuit interrupter is disposed on a first side of a PCB and an auxiliary switch is at least partially disposed on a second side of the at least one PCB. The auxiliary switch includes a switch throw element movably extending through an opening in the PCB between the first state and the second state, the auxiliary switch being configured to decouple at least a portion of the fault protection circuit assembly from the plurality of line terminals in the second state.

Abstract: The present invention is directed to an electrical wiring protection device for use in coupling an AC power distribution system to at least one electrical load. The device includes an automated self-test circuit coupled to the AC power distribution system. The automated self-test circuit is configured to generate at least one simulated fault signal during a first predetermined half-cycle of AC power. A detector circuit is coupled to the automated self-test circuit. The detector circuit generates a detection signal in response to the at least one simulated fault signal. An interval timing circuit is coupled to the test circuit. The interval timing circuit is configured to enable the automated self-test circuit to generate the at least one simulated fault signal during a first predetermined interval and not enable the test circuit during a subsequent second predetermined interval. The first predetermined interval and the second predetermined interval are recurring time intervals.
