Abstract:
1. A circuit interrupting device comprising: a test button; a series of circuits comprising: a reset button; wherein when said circuit interrupting device is properly wired with power on and at a tripped state, a depression of said test button generates a simulated fault which is detected by said main control circuit; wherein when components in said main control circuit work properly, a control signal is generated by said main control circuit and transmitted to said end-of-life detection circuit to activate said reset/trip circuit and generated an indication signal; whereby after said indication signal is displayed, said reset button is able to be depressed to reestablish an electrical continuity of said circuit interrupting device; and wherein when said components in said series of circuits do not work properly, said depression of said test button does not allow said fault signal to be generated and passed through said series of circuit which results in no production of said indication signal; whereby said reset button is not able to be depressed and no electrical continuity is reestablished.
