Abstract
An electronic test circuit for the self-testing of fault detection devices such as GFCI's, AFCI's and RCD's enhances the safety of such devices by automatically testing the function of all components of these detection components without the need for manual intervention. This self-test device tests the functioning of the primary circuit breaker and detects failure modes such as welded contacts in the circuit breaker. By using a secondary, “one-shot” circuit breaker, power may be safely and automatically removed from a malfunctioning fault detection device.
