Abstract
An arc fault circuit interrupt (AFCI) tester device includes a housing and a circuit assembly disposed within the housing. The circuit assembly includes a first load switching circuit for creating a pulse pattern having a plurality of pulses. The circuit assembly includes a second load switching circuit for creating an overlay signal superimposed upon at least one pulse of the plurality of pulses. The AFCI tester device includes an interface receiving the plurality of pulses and the overlay signal. The interface extends outside of the housing and is adapted for electrically coupling the circuit assembly to the AFCI device under test (DUT). The interface is adapted to transmit the pulse pattern and the overlay signal to the AFCI DUT.
