Abstract
The present invention is directed to a protective device configured to be coupled between an AC power source and an electrical load. A ground continuity monitor is coupled to the ground conductor, the ground continuity monitor being configured to detect a ground discontinuity condition in the ground conductor. A circuit interrupter mechanism is configured to interrupt electrical continuity in a tripped state and establish electrical continuity in a reset state. A self-test circuit is coupled to the ground continuity monitor and configured to perform a simulated ground continuity test that simulates the ground discontinuity condition. The self-test circuit provides a test failure signal when the ground continuity monitor fails to provide an output signal in response to the simulated ground continuity test. The test failure signal is configured to trip the circuit interrupter mechanism.
