Claim Text:
1. A compartment of an arc resistant enclosure for an electrical component comprising: a plurality of wall structures defining an interior space for housing an electrical component, one of the wall structures having aperture structure for permitting internal pressure and gasses to flow there-from and vent from the compartment; a stop structure associated with the aperture structure; and flap structure associated with the aperture structure and movable from a closed position covering the aperture structure to an opened position extending outwardly of the compartment permitting the internal pressure and gasses to exit the compartment through the aperture structure, wherein, in the closed position, a portion of the flap structure engages the stop structure to prevent the flap structure from collapsing into the interior space of the compartment, wherein the flap structure includes a pair of flaps, each flap being hinged to the compartment at one end thereof and each flap having a free end such that when moving towards the closed position, the free ends move towards each other and generally abut near a center of the aperture structure in the closed position thereof, and when moving towards the opened position, the free ends move away from each other, and wherein the flaps have opposing openable sides, and the compartment further comprises members having portions extending outwardly and transversely from the one wall structure and adjacent to each of the openable sides of the flaps for preventing external gasses from getting under the openable sides in the closed position of the flaps.
