ABSTRACT:
An arc fault circuit breaker includes a panel having a first side and an opposite second side, a housing coupled to the opposite second side of the panel, separable contacts, an operating mechanism structured to open and close the separable contacts, and a trip mechanism cooperating with the operating mechanism to trip open the separable contacts. The trip mechanism includes a test circuit structured to simulate a trip condition to trip open the separable contacts, and a proximity sensor disposed on or within the housing proximate the opposite second side of the panel. The proximity sensor is structured to sense a target to actuate the test circuit when the target is disposed proximate the first side of the panel and opposite the proximity sensor.
