Abstract: An electrical enclosure includes a main cabinet and a modular cabinet removably secured to the main cabinet. The main cabinet includes a bus compartment that includes a busbar assembly, and the bus compartment is located between an end wall of the main cabinet and a partition opposite the end wall. The modular cabinet is comprised of interlocking compartment modules. Each compartment module interlocks with an adjacent compartment module. Each compartment module includes first and second side panels. Each side panel includes an alignment member that engages an alignment member of a respective side panel of the adjacent compartment module. Each compartment module also includes a base that extends between the first and second side panels and a terminal wall that joins the first and second side panels. The terminal walls of the interlocking compartment modules engage to form a structural wall of the modular cabinet.

Abstract: A system for transferring heat generated in an electrical enclosure includes run-in buses, a thermally conductive plate, and at least one contact assembly secured to the plate. Each pair of adjacent run-in buses is separated by a space. The plate has at least one opening extending therethrough, and the plate receives the run-in buses through the at least one opening. The at least one contact assembly has spaced apart fingers that partially cover the at least one opening of the plate, and adjacent fingers define a slot. Each of the fingers is located in a space between adjacent run-in buses, and each of the run-in buses is located in a slot when the fingers are located in the spaces between adjacent run-in buses. The run-in buses and contact assembly fingers are oriented in an interleaved pattern.

Abstract: An electrical enclosure includes a plurality of walls. The electrical enclosure also includes at least one compartment defined, at least in part, by the plurality of walls, and at least one ventilation opening formed in one of the plurality of walls. The at least one ventilation opening provides a flow path from the at least one compartment. At least one closure is provided on the one of the plurality of walls at the at least one ventilation opening. The at least one closure is responsive to a pressure wave to selectively close the at least one ventilation opening and re-open the at least one ventilation opening after the pressure wave has passed from the electrical enclosure.

Abstract: An electrical enclosure includes a first wall having an exhaust opening, a second wall, and a third wall. The electrical enclosure also includes at least one circuit breaker compartment, a line compartment arranged between the third wall and the at least one circuit breaker compartment, and an exhaust duct extending through the electrical enclosure between the first wall and the second wall. The exhaust duct is fluidically connected to the exhaust opening and each of the at least one circuit breaker compartments. At least one passage extends between the line compartment and the at least one circuit breaker compartment through the exhaust duct. The at least one passage is substantially fluidically isolated from the exhaust duct.
