Abstract: A plug-in ground fault interrupting type circuit breaker includes a resilient jaw for engaging the neutral bar in a loadcenter. The jaw is formed at the end of a conductive strap which passes through the window of a transformer and terminates in a screw terminal for attachment to a neutral load conductor. The phase conductive path also includes a conductive strap that is coupled at one end to a phase load conductor terminal and at its other end to the breaker trip mechanism. The transformer and both strap conductors are mounted to a printed circuit board that is included within the breaker housing. The invention eliminates the separate pigtail for connecting the load neutral conductor to the loadcenter neutral bar.
