Abstract: A fault interrupt module includes a detector circuit, a counter circuit, and a switch circuit. The detector circuit is configured to detect faults as a difference in current between an input power line and a neutral line. The counter circuit configured to increment a fault count each time a fault is detected by the detector circuit, and the switch circuit is configured to terminate power to a load upon the fault count reaching a threshold count within a threshold time period.
