Abstract: A method and an arrangement of components in a switchgear enclosure having multi-phase electrical power run-in and run-back bus bars. The circuit breaker is also provided in the enclosure. The arrangement of components is configured to provide interchangeable modularity of components within the enclosure. The arrangement of components includes a run-in mounting base including a primary disconnect member for each electrical phase. A run-back mounting base, including a primary disconnect member for each electrical phase is also included. The run-in mounting base and the run-back mounting base are configured to interchange the line and load side of the circuit breaker. Another embodiment of the arrangement includes a bridge coupled to one of the run-in mounting base and run-back mounting base, with the bridge configured to position each primary disconnect member for alignment with the circuit breaker.

Abstract: A method and modular insulation system for an electrical equipment enclosure having multi-phase bus bars and a mounting base for mounting electrical equipment. The insulation system comprises a plurality of components including a plurality of side isolation barriers with each barrier defining at least one slot proximate one edge of the barrier and having at least one tab along another edge of the barrier. A side barrier adapter is configured to engage the isolation barrier and to engage the mounting base. An inner isolation barrier is configured to isolate at least two of the vertical bus bars and couple to the mounting base. A vertical bus rearwall defining a plurality of slots proximate at least two edges of the cover is fastened to the inner isolation barrier. A plurality of corner connectors is configured to engage one of the cover slots and the side isolation barrier slots.

Abstract: A method and an electric bus bar in an electrical enclosure. The electrical bus bar includes a web portion having a first side and a second side. A pair of flanges are formed with one flange on each side of the web portion and positioned perpendicular to the web portion. The sum of the lengths of both flanges is less than the width of the web portion.

Abstract: A method and an alignment arrangement for a circuit breaker cradle configured to mount in a switchgear enclosure. The switchgear enclosure includes a mounting base. The alignment arrangement includes a first cradle alignment notch defined in one end of the mounting base. A second cradle alignment notch is defined in another end of the mounting base. A first alignment tab is defined on one edge of the cradle and positioned on the cradle to align with the first cradle alignment notch. A second alignment tab is defined on another edge of the cradle and positioned on the cradle to align with the second cradle alignment notch. The two alignment tabs will mate and interlock with the two notches in the mounting base to align the cradle horizontally and vertically in the switchgear enclosure.

Abstract: A method and a mounting plate system for electrical equipment in a switchgear cabinet having spaced apart frame members. The mounting plate system comprises a first mounting plate having a plurality of orifices located proximate an outer edge of the first mounting plate. A second mounting plate having a plurality of orifices located proximate an outer edge of the second mounting plate, wherein the first and second mounting plates are configured to couple to the electrical equipment in the frame members, releaseably secure the electrical equipment to the frame member from the rear of the switchgear cabinet and facilitate removal of the electrical equipment from the front of the switchgear cabinet. Another embodiment, the mounting plate system provides one of the first and second mounting plates defining a through-hole configured to accept the wire.
