1. An insulator for providing insulation between walls of an assembly and a bus bar which extends through the assembly, the insulator comprising:
a contoured mounting member having a contoured edge, the contoured edge having side walls and end walls, the side walls extend in a direction which is essentially parallel to each other and which is non-perpendicular to a line which extends through a rotational center of the mounting member, the end walls extend from the side walls at an angle other than 90 degrees, the end walls extend in a direction which is essentially parallel each other; a bus bar-holding opening extending through the mounting member; mounting flanges provided on the mounting member, the mounting flanges extend from proximate the bus bar-holding opening to diagonally opposed corners of the mounting member; mounting openings provided on the mounting flanges of the mounting member, the mounting openings being offset from the geometrical centerline of the bus bar-holding opening by more than the radius of the mounting hardware; the contoured mounting member has twofold rotational symmetry; whereby the mounting hardware of the insulator and mounting hardware of an adjacent insulator may be interleaved transversely in the direction of the adjacent insulator having two-fold rotational symmetry to allow for close placement of the insulators while maintaining required spacing to provide proper electrical isolation. |
