Plug-on neutral circuit breakers include an AFCI OR GFCI circuit breaker housing, a neutral conductor with an external end portion extending from the AFCI/GFCI circuit breaker housing, and a clip assembly attached to the neutral conductor at a specific length configured to align with the loadcenter neutral bar location. The clip assembly includes a conductive clip with downwardly extending, spaced apart legs. The legs are sized and configured to clamp against opposing sides of a neutral bar.
