Insulators are positioned at each of the insulator-mounting openings. Each insulator includes a mounting member having contoured edges. A bus bar holding opening extends through the mounting member. Mounting openings are provided on the mounting member. The mounting openings being dimensioned to receive mounting hardware therein. The mounting openings are offset from the geometrical centerline of the bus-bar holding opening by more than the radius of the mounting hardware. The mounting hardware of adjacent insulators may be thereby interleaved to allow for close placement of the insulators while maintaining required spacing to provide proper electrical insulation. ## Claims ### Claim 1 An insulator for providing insulation between walls of an assembly and a bus bar which extend through the assembly, the insulator comprising: a contoured mounting member having a contoured edge;
