Abstract: An electrically insulative case for an electrical device includes a housing defining an interior space. The electrically insulative case also includes a frame operatively coupleable to the housing in a plurality of orientations. The frame defines at least one opening that provides access to the electrical device. An inner sidewall of the frame extends into the interior space. The electrically insulative case further includes a restrictor coupleable to the electrical device such that the restrictor extends adjacent to the frame. The restrictor is arranged to inhibit objects from moving from an exterior of said housing into the interior space.

Abstract: An interlocking system for a circuit breaker assembly including a circuit breaker having a plurality of contacts includes a racking screw coupled to the contacts that changes a position of the circuit breaker when engaged by a tool. The interlocking system also includes a front panel defining an opening through which the racking screw is accessible, an access door coupled to the front panel and configured to selectively cover the opening, and an access door stopper coupled to the front panel. The interlocking system also includes a trip assembly coupled to the access door stopper. Each of the access door, the access door stopper, and the trip assembly are moveable between a first position and a second position such that moving to the first position triggers delivery of a trip signal to the circuit breakers to open the plurality of contacts, and wherein, in the second position, the access door is fully open to enable access to the racking screw through the front panel.
