Abstract
A terminal assembly for a circuit interrupter has a plurality of pairs of metallic spaced parallel flat load terminals with the flat surfaces of the terminals of a pair opposed to each other, the pairs of terminals being positioned side-by-side with spaces therebetween, there being one pair for each phase of the interrupter. Two side walls of insulating material are provided between each side-by-side pair of terminals and abutting each other, and two end walls of insulating material are provided on the outside of the outermost pairs of the terminals. The side walls and end walls have grooves therein holding the side edges of the terminals, the terminals projecting outwardly from between the side walls and end walls. Bolts extend through aligned bolt receiving holes. A plurality of projections are provided at spaced intervals around the holes on the opposite sides of the walls of the grooves, and there are recesses in the walls between adjacent projections, the projections on one abutting wall engaging in the recesses around the corresponding aligned holes of the other abutting wall. A pair of metallic plates are provided over the outer surface of the end walls, the projections on t…
