Abstract: A tester for an arc fault circuit interrupter that can selectively simulate and apply electrical arc faults and nuisance loads to at least one device under test (DUT). The tester includes a power supply, a test controller, and test circuitry coupleable to a DUT. AC power input is provided to the DUT and the power supply, which regulates the AC power input to a DC level for powering the test controller. The test circuitry full wave rectifies AC current returning from the DUT, and the test controller controls a switch in the test circuitry. When the switch is on, the AC current flows through the DUT, the full wave rectifier, the load, and the switch to ground. To simulate an arcing condition, the test controller turns the switch on and off at random intervals. To simulate a nuisance load condition, the test controller turns the switch on and off at periodic intervals. In this way, proper operation of the DUT can be verified under both arcing and nuisance load conditions.

Abstract: An apparatus and method for detecting arc faults that have reduced susceptibility to nuisance tripping. The apparatus includes a current sensor, an input sense circuit, an arcing sense circuit, a power supply, a tripping (firing) circuit, a processor, and an electromechanical interface. The current sensor monitors a power input comprising an AC current, and provides high frequency components of the AC current to the input sense circuit. The input sense circuit filters and rectifies the AC signal, and provides the rectified signal to the arcing sense circuit. The arcing sense circuit provides a voltage level accumulated over a predetermined time period, and digital signals indicative of possible electrical arcing occurring during the sampling period, to the processor.
