1. A plenum assembly for coupling with an arc resistant cabinet defined by at least two vertical sections, each of the vertical sections terminating at an opening along a substantially horizontal cabinet plane defined by a top side of the cabinet, the plenum assembly comprising:
at least one chamber including a base and a plurality of sides, the base including at least one opening for aligning with the openings of the vertical sections, and at least one of the sides including at least one opening for communicating with at least one exhaust conduit, the at least one base opening and the at least one side opening defining a pathway for exhaust products from the cabinet to the at least one exhaust conduit; at least one deflector plate disposed within the at least one chamber at an angular orientation with respect to the cabinet plane, the at least one deflector plate moveable from the angular orientation in response to exhaust products generated in the cabinet: and, at least one exhaust conduit in communication with the at least one side opening, the at least one exhaust conduit comprising a plurality of modules in accordance with: 1) the length of the plenum assembly, and 2) the distance to an outlet of an enclosure enclosing the cabinet: wherein the at least one chamber includes a plurality of chambers, and the at least one exhaust conduit includes a plurality of exhaust conduits, each of said exhaust conduits is connected to a corresponding said chamber, and each said exhaust conduit leads to at least one terminal assembly for deflection of exhaust products out of an area enclosing the cabinet. |
