| 1. A module having a relay and transformer connectable to a printed circuit board (PCB) in a ground fault circuit interrupter
(GFCI), the module comprising:
a first transformer having a core and electrically coupled to a first set of terminals for connection to a printed circuit
board (PCB);
a second transformer magnetically coupled to said first transformer is electrically coupled to a second set of terminal for
connection to said PCB;
a double pole single throw (DPST) relay having a pair of stationary contacts, a pair of movable contacts and an electrical
coil surrounding a magnetic core; and
a structural support for mounting said first transformer, said second transformer, and said relay independent of the printed
circuit board and in fixed relative position;
wherein a radial axis of each of said first transformer, said second transformer and said relay are substantially parallel
with respect to each other, and wherein at least one cross-section of one of said first and said second transformers taken
along a plane perpendicular to said radial axes of said first and second transformers is coplanar with at least one cross-section
of said relay taken along a plane perpendicular to said radial axis of said relay.
