Abstract
An annunciation system which will detect the majority of failed breakers and indicate to the consumer when a breaker needs to be replaced, but does not put the consumer in an emergency situation where critical loads have lost power. The annunication system provides a visible and audible indication of the failure of a breaker to trip either as a result of fault current conditions or a test of a ground fault or arc fault circuit.
