Abstract: An improved electrical system may be provided by electrically isolating exposed live fasteners and bus clamps in power distribution systems by attaching electrically insulating snap-based cover assemblies to the live fasteners and bus clamps. A cover assembly may include a plate element and an electrically insulating cap element. The plate element may have a plate opening and a beveled edge, and the electrically insulating cap element may have a cap edge followed by an interior recess. The cap element and the plate element may be held together by snapping the cap element over the plate element such that the beveled edge fits into the interior recess and the cap edge fits below the beveled edge. The cover assembly may be attached to a fastener or bus clamp via the plate opening.

Abstract: An improved electrical system may be provided by electrically isolating complex bus geometries by using one or more substantially flat and electrically insulating sheets. The sheet may have one or more fold lines which allow the sheet to fold in multiple directions and ways over varying configurations of power conductors. The sheet may fit within the constraints of preconfigured electrical system components without the need for redesigning such components. The sheet may have a dielectric strength per mil effective to isolate power conductors based on maximum charge and proximity of the power conductors.
