Abstract: An electrical enclosure apparatus includes a protective apparatus that permits forced-air cooling of the interior of the enclosure while resisting structures that are within in the interior from being blown out of the electrical enclosure as a result of an arc event or other event. The protective apparatus includes a flow apparatus formed from one or more blocks of ceramic material having foamed therein a plurality of elongated flow channels. The flow apparatus is supported inside a duct with the use of a support apparatus. The ceramic material from which the flow apparatus is formed is configured to withstand the heat that may be experienced in an arc event and is additionally configured to be sufficiently rigid and tough to retain within the duct any structures within the enclosure from being blown out of the protective apparatus, thereby protecting personnel who may be in the area.

Abstract: An apparatus includes an enclosure comprising first and second abutting compartment and at least one cable passing between the first and second compartments through a sealing multi-cable transit mounted in a wall shared by the first and second compartments. The first compartment may contain arc-generating equipment and the second compartment may contain equipment vulnerable to arc damage. The first compartment may include a medium-voltage cubicle and the second compartment may include a low-voltage control cubicle.

Abstract: An arc-resistant electrical enclosure includes an arresting system that permits forced-air cooling of the interior region to occur during ordinary operation of the enclosure while resisting the flow of hot gases, plasma, and flames to the exterior of the electrical enclosure in an arc event or other event. The arresting system advantageously includes a louver apparatus and a cover apparatus that work in conjunction to resist the flow of gases, plasma, and flames to the exterior of the cabinet in an arc event. The louver apparatus includes louvers that can be moved from an open state to a closed state responsive to a predetermined fluid pressure impinging on the louvers. The cover apparatus includes a fire blocking panel that permits fluid flow therethrough during ordinary operation but which, responsive to a flame, initiates a transformation from one state to another state wherein the openings resist the communication of flames therethrough.
