Abstract
A system includes a number of electrical switching apparatus having separable contacts, an operating mechanism structured to open and close the separable contacts, a trip mechanism cooperating with the operating mechanism to trip open the separable contacts, a test circuit structured to test the trip mechanism and determine a failure to protect condition thereof, and a communication circuit structured to communicate the failure to protect condition. The system also includes an electrical distribution panel having a housing housing the number of electrical switching apparatus, and a communication interface structured to receive the failure to protect condition from the communication circuit and annunciate the failure to protect condition.
