ABSTRACT:
A ground fault circuit interrupter (GFCI) includes a GFCI controller configured to detect for ground faults and to periodically perform a self test. The self test may be performed during a positive half cycle of an AC line voltage coupled to a load by the GFCI. The self test may include testing of a critical component of the GFCI without opening load contacts coupling the AC line voltage to the load. The self test may further include testing of monitoring coils in the GFCI.
