Abstract

An electrical enclosure includes a plurality of exterior panels defining a volume and an enclosure ventilation assembly adjacent to the volume. The enclosure ventilation assembly includes a ventilation panel including a ventilation aperture defined therethrough, a ventilation cover assembly, and an arc shield assembly. The ventilation cover assembly is coupled to the ventilation panel to cover the ventilation aperture and is configured to allow gasses into the electrical enclosure through the ventilation aperture, to inhibit an intrusion of water into the electrical enclosure, and to inhibit egress of an arc fault discharge from the enclosure. The arc shield assembly includes an arc shield rotatably coupled to the enclosure ventilation assembly and configured to rotate between a first, open position and a second, closed position, wherein the first, open position facilitates a flow of gasses into the electrical enclosure and the second, closed position inhibits an arc fault discharge egress.
