METHOD OF ACTUATING A TEST FUNCTION OF AN ELECTRICAL SWITCHING APPARATUS AT A PANEL AND ELECTRICAL SWITCHING APPARATUS EMPLOYING THE SAME
First Claim
1. A method of actuating a test function of a circuit interrupter including a housing, said circuit interrupter being coupled to a panel having a first side and an opposite second side, said method comprising:
- coupling said housing to said panel at the opposite second side thereof;
disposing a proximity sensor on or within said housing and proximate the opposite second side of said panel;
disposing a target proximate the first side of said panel and opposite said proximity sensor;
sensing said target with said proximity sensor; and
responsive to said sensing said target, actuating said test function of said circuit interrupter.

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.
