Abstract: An electrical enclosure includes a plurality of walls. The electrical enclosure also includes at least one compartment defined, at least in part, by the plurality of walls, and at least one ventilation opening formed in one of the plurality of walls. The at least one ventilation opening provides a flow path from the at least one compartment. At least one closure is provided on the one of the plurality of walls at the at least one ventilation opening. The at least one closure is responsive to a pressure wave to selectively close the at least one ventilation opening and re-open the at least one ventilation opening after the pressure wave has passed from the electrical enclosure.

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.

Abstract: A shaft coupling element comprising a first portion configured for connection to a shaft and a second portion configured for connection to a secondary component. The first portion comprises first and second spaced apart side walls with a partial cylindrical portion extending therebetween to define a shaft receiving slot. A safety notch extends through the partial cylindrical portion adjacent the axial opening in to the shaft receiving slot to define a radial opening from the shaft receiving slot.

Abstract: A cable management enclosure includes: a side; a sliding drawer; a fiber slack manager mounted to the side, the fiber slack manager includes: a first link having a first end and a second end, the first end pivotally secured to the side; and a second link pivotally coupled to the second end of the first link, the second link pivotally secured to the sliding drawer. A cable management enclosure also includes: a main body portion having a first side and a second side; a sliding drawer disposed between the first side and the second side; a patch panel disposed between the first side and the second side, the patch panel having a plurality of openings, the patch panel is mounted to the sliding drawer; wherein the sliding drawer includes a front portion and a rear portion, the first portion slides relative to the rear portion, the front portion and the rear portion slide relative to the first side, the front portion is smaller than the rear portion.
