ABSTRACT:
An electric circuit breaker or switch is disclosed having a plug-in connection means with an auxiliary bolt-operated means for enhancing the electrical and mechanical connection between the circuit breaker and a panelboard terminal. A U-shaped terminal clip is mounted in an opening in the circuit breaker case. The terminal clip engages over and frictionally grips a stab terminal on a panelboard to provide an electrical connection. A C-shaped clamp fits over and partially encircles the terminal clip in such a manner that the free ends of the clamp arms project inwardly toward and contact the legs of the terminal clip. A screw, which may be non-conductive, is retained in a bore in the molded case of the circuit breaker, extends into the terminal clip opening and engages a threaded hole in the C-shaped clamp. Rotation of the screw draws the C-shaped clamp upwardly within the terminal clip opening and causes the clamp arms to move up onto wider, tapered portions of the clip legs thereby urging the legs of the clip into tighter engagement with the panelboard terminal.
