摘要:
The present invention is directed to an electrical wiring device that includes a test circuit that is configured to generate a recurring simulated fault signal. A detection circuit is configured to generate a test detection signal in response to the recurring simulated fault signal. An end-of-life monitor circuit is configured to generate an end-of-life detection signal if the test detection signal is not generated within a first predetermined period of time. At least one indicator is configured to emit an indication signal in response to the end-of-life detection signal. A response mechanism is configured to decouple the plurality of line terminals from the plurality of load terminals after a second predetermined period of time has elapsed following the end-of-life detection signal.
