Abstract: Embodiments of a plug-in unit for an electrical enclosure are disclosed. The plug-in unit includes at least one stab configured to engage a bus, a stab shaft coupled with a base of the at least one stab, and a stab translation mechanism configured to translate the stab shaft such that the at least one stab translates from a retracted position to an extended position.

Abstract: A stab for use in a plug-in assembly includes a stab piece and a lug. The stab piece includes one or more contact arms configured to engage a bus bar, and a base portion coupled to the one or more contact arms. The base portion is configured to be coupled to a stab shaft for rotating the stab about a rotational axis to transition the stab from a retracted position to an extended position. The lug is coupled to the stab piece and configured to receive wire for transmitting power from the bus bar to an electrical component. The lug is configured to be deformed around the wire to hold the wire when a crimping force is applied to the lug. The lug is configured to hold the wire at a position approximately centered on a rotational axis of the stab shaft when the lug is deformed by the crimping force.

Abstract: A bus support system is disclosed that accommodates three-wire three-phase circuitry and four-wire three-phase circuitry. A main bus support element is designed to receive horizontal bus bars and vertical bus bars for installation in an electrical enclosure. The main support element is supplemented by an add-on bus support element where a neutral bus is required for four-wire three-phase operation.
