Abstract
Methods, systems, apparatus and devices for an arc resistant electrical enclosure that includes a duct system of adjacent pressure relief chambers separated by flame arresting ventilation partitions to provide a torturous mechanical maze to relieve internal pressure and extinguish internal hot flames within the flame arresting duct system prior to exiting the enclosure expelling gasses into the external environment. The adjacent partitioned pressure relief chambers for routing pressure and or flames through the duct system with ninety degree turns from one pressure relief chamber into the next adjacent pressure relief chamber. In an embodiment, a set of ventilation panels is located within one or more of the adjacent pressure relief chambers and each next pressure relief chamber can have a volume that is less than the volume in the preceding chamber.
