Arc-resistant switchgear cabinet

摘要

An arc-resistant switchgear cabinet includes a frame disposed on a floor and a door movably mounted on the frame. The frame includes a floor plate that is disposed against the floor and that includes a plurality of pins extending vertically upward from the floor plate. The door includes a plurality of corresponding receptacles into which the pins are received when the door is in a secured position. The pins in the receptacles resist the lower end of the door from moving in a horizontal direction away from the frame in the event of an arcing fault. A pair of bolts additionally fasten the lower comers of the door to the frame. The switchgear cabinet further includes interlocking tabs formed on the frame and on the door that overlap one another when the door is in the secured position.
