Summary: | A circuit breaker includes separable contacts; a load conductor; a neutral conductor; and an operating mechanism structured to open and close t he separable contacts. An arc fault trip circuit cooperates with the operating mechanism and trips open the separable contacts responsive to detection of an arc faul t condition associated with current flowing through the separable contacts. A ground fau lt trip circuit cooperates with the operating mechanism and is structured to trip op en 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. |
