Abstract
An electrical enclosure includes at least one circuit breaker compartment and a cover mounted thereon. The cover includes an opening receptive of at least one circuit breaker. A gasket extends about at least a portion of the opening. The gasket includes an inner seal assembly and an outer seal assembly. The outer seal assembly is positioned to engage the at least one circuit breaker when the cover is in a closed position. The inner seal assembly is movable between a non-deployed configuration spaced from the at least one circuit breaker and a deployed configuration engaged with the at least one circuit breaker. The inner seal assembly is responsive to a pressure wave in the at least one circuit breaker compartment to move from the non-deployed configuration to the deployed configuration and substantially prevent out gassing through the opening in the cover.
