ABSTRACT:
A circuit breaker includes separable contacts; a load conductor; a neutral conductor; and an operating mechanism structured to open and close the separable contacts. An arc fault trip circuit cooperates with the operating mechanism and trips open the separable contacts responsive to detection of an arc fault condition associated with current flowing through the separable contacts. A ground fault trip circuit cooperates with the operating mechanism and is structured to trip open the separable contacts responsive to detection of a ground fault condition associated with current flowing through the separable contacts, the load conductor and the neutral conductor. The arc fault trip circuit includes an integration capacitor, and the ground fault trip circuit includes an output to the integration capacitor.
