ABSTRACT:
An arc-resistant enclosure for electrical switchgear which includes solid front and back walls, a pair of solid side walls joined to the front and back walls, a ventilated roof joined to the side walls and the front and back walls, and a ventilated base joined to the side walls and the front and back walls. Internal partitions divide the space enclosed by the front, back, side, top and bottom walls into multiple compartments for housing different types of components. The ventilated base forms air-intake ports for admitting ambient air into a plurality of the compartments, and the ventilated roof forms air-exhaust ports for allowing air to be exhausted from the compartments. As air inside the enclosure is heated by the switchgear, the hot air rises through the switchgear compartments and is exhausted through the top air-exhaust ports, and replacement ambient air is drawn into the bottoms of the compartments through the air-intake ports.
