Abstract
A plug-in type electric circuit breaker utilizing a detachably fastened stab assembly for interconnecting the circuit breaker to current carrying members such as bus bars. The stab assembly incorporates a plurality of opposed, independently movable spring-biased contact fingers having limited axial and arcuate motion allowing for good electrical and mechanical interconnection between misaligned circuit breakers and bus bars and reduction in the amount of force required for installation while preventing the engagement of the circuit breaker with oversized or undersized conductors.
