摘要
A ground fault circuit breaker has line and neutral bus bars extending through the center apertures of two laterally spaced toroidal coils to form the primaries of ground fault sensing transformers. The bus bars have flat center sections extending between the two coils parallel to the coil end faces and offset laterally by flat laterally extending legs at each end which are bent transverse to the end faces of the coils and extend through the coil apertures in flat confronting relation. The leg on one end of the neutral bus bar has a terminal portion bent into a plane parallel to the center section with a crimp at the end for attachment to a neutral pigtail.
