Abstract

A circuit interrupter including a line conductor, a neutral conductor, separable contacts structured to open to interrupt current flowing through the line and neutral conductors, a circuit interrupter circuit structured to detect a fault based on current flowing through the line and neutral conductors and to output a trip signal in response to detecting the fault, a trip circuit structured to trip open the separable contacts in response to the trip signal, and an audible indicator circuit electrically connected between the line and neutral conductors and being structured to output an audible sound in response to the trip circuit tripping open the separable contacts.
