Abstract

The present invention provides a circuit interrupting device which can test the conditions of the components in the circuit interrupting device (i.e., the end-of-life test) through the depression of a test button. The circuit interrupting device also possesses reverse wiring protection, including the ability to cutoff power on the user accessible plugs of the face plate when the device is reverse wired or miswired. The circuit interrupting device contains a test button, a reset button, and a series of circuits (including, but not limited to, a main control circuit, an end-of-life detection circuit, and a reset/trip circuit). A depression of the test button generates a simulated fault, which is detected by the main control circuit. When the components in the main control circuit work properly, a control signal is generated by the main control circuit and transmitted to the end-of-life detection circuit to activate the reset/trip circuit and generated an indication signal. After the indication signal is displayed, the reset button is able to be depressed, which sends a signal to the end-of-life detection circuit, which in turn forwards the signal to the reset/trip circuit to reestablish the electrical continuity of the circuit interrupting device.
