Abstract:
1. An electrical wiring protection device comprising: a housing assembly including a plurality of line terminals and a plurality of load terminals, the plurality of line terminals being configured to be coupled to a source of AC power; a fault detection circuit including a power supply coupled to at least one of the plurality of line terminals and configured to generate a fault detection signal in response to detecting at least one fault condition in the electrical distribution system; a circuit interrupter coupled to the fault detection circuit, the circuit interrupter being configured to couple the plurality of line terminals to the plurality of load terminals to form a conductive electrical path in a reset state, and decouple the plurality of line terminals from the plurality of load terminals in response to a fault detection signal in a tripped state; and a voltage transient suppression circuit coupled to the plurality of line terminals and the power supply, the voltage transient suppression circuit generating a leakage current in the event of a voltage transient suppression circuit failure, the leakage current simulating the at least one fault condition, the voltage transient suppression circuit also being configured to decouple the power supply from the source of AC power in the tripped state.
