Claim 22:
23. A method for selectively connecting a source of AC power from a line side to a load side of a circuit interrupter device, comprising:
initializing, by one or more controllers of the circuit interrupter device that are powered from the source of AC power from the line side, a self-test;
determining, by the one or more controllers, whether the self-test was successful;
outputting, by the one or more controllers, a self-test result signal based on whether the self-test was successful;
staying, by an electrically-held relay of the circuit interrupter device in electrical communication with the one or more controllers and powered from the source of AC power from the line side, in an OFF state until the self-test result signal indicates the self-test was successful, wherein when in the OFF state, the load side of the circuit interrupter device is not in electrical communication with the source of AC power, and when in the ON state, the load side of the circuit interrupter device is in electrical communication with the source of AC power; and
entering, by the electrically-held relay, an ON state if the self-test result signal indicates the self-test was successful.
