Abstract:
An adapter (102) is for mounting an electrical switching apparatus, such as a circuit breaker (106), on the back panel (10) of an enclosure, such as a switchgear cabinet. The back panel has at least one aperture (12). The adapter includes a first end portion (116) coupled at or about the aperture (12) of the back panel, an engaging portion (120) and engaging and securing the circuit breaker to the adapter, a fastener (26), and a second end portion (122) disposed distal from the first end portion and including an elongated slot (124). The elongated slot receives the fastener in order to couple the adapter to the back pannel when the fastener is fastened, while enabling adjustement of the adapter and the circuit breaker coupled thereto, with respect to the back panel, when the fastener is unfastened. The first end portion, the engaging portion and the second end portion form a single piece adapter. An enclosure assembly is also disclosed.
Abstract:
An arc fault circuit breaker includes a housing, separable contacts mounted within the housing, an operating mechanism structured to open the separable contacts when actuated, and a trip assembly including an arc fault trip mechanism structured to generate a trip signal in response to detecting an arc fault. The trip assembly is structured to actuate the operating mechanism in response to the trip signal. A contact clip spring is structured to mechanically couple and electrically connect the circuit interrupter to a neutral bar. The contact clip spring is in electrical communication with the arc fault trip mechanism.
Abstract:
An enclosed metering and protective electrical apparatus (2;2;64) includes an enclosure (4), a meter socket (6;6) within the enclosure structured to input a power circuit (8) and to engage a power meter, and a circuit interrupter (10) within the enclosure including an operating handle (12) and a trip mechanism (14). The circuit interrupter is structured to output the power circuit from the meter socket to a load (16) and to interrupt the power circuit. A neutral current sensor (18) within the enclosure is structured to detect a ground fault operatively associated with the power circuit and responsively cause the trip mechanism of the circuit interrupter to interrupt the power circuit. A disconnect handle (22) substantially external to the enclosure includes linkage (24) extending within the enclosure and cooperating with the operating handle of the circuit interrupter to open and close the circuit interrupter.
