MULTI-POLE GROUND FAULT CIRCUIT BREAKER ABSTRACT OF THE DISCLOSURE Ground fault circuit breaker structure character- ized by an insulating integral housing having side-by-side compartments that are separated by partition walls. A cir- cuit breaker is located in each of two compartments and a ground fault detector is located in a compartment between the circuit breakers and isolated from the circuit breakers by the partition walls. The ground fault detector comprises a differential transformer comprising a current monitoring core, a plurality of primary windings on the core and com- prising one of a line conductor of each circuit breaker, and a neutral conductor of an AC electrical distribution system, a secondary winding sensing current unbalance between the primary windings, means responsive to a predetermined sensing signal to open the line conductor; the line conductor of both circuit breakers extending between the corresponding circuit breaker trip means and through aperture means in the partition wall and through the magnetic core and back through the aperture means to the load terminal. The line conductors of both circuit breakers being looped through the coil in opposite current directions and located in the coil at sub- stantially 120° from the location of the neutral conductor extending therethrough. The means responsive to a predeter- mined sensing signal including a pivotally movable member extending through the aperture means and movable against the trip member to unlatch the trip member.
