1. A ground fault circuit interrupter self-test circuit comprising:
a current transformer coupled to a controller;
a silicon controlled rectifier (SCR) test loop coupled to the controller;
a ground fault test loop coupled to the controller; and
a solenoid coupled to the controller;
wherein the SCR test loop is configured to conduct an SCR self-test and the ground fault test loop is configured to conduct a ground fault self-test;
wherein an SCR is configured to activate the solenoid to deny power to a load upon one of the SCR self-test or the ground fault self-test being identified as failing; and
wherein one of the ground fault self-test or the SCR self-test fails two or more consecutive times before the SCR activates the solenoid.
