Abstract: A wall for an electrical equipment enclosure includes an outer panel, an inner panel having a first side facing a chamber of the enclosure and a second side facing the outer panel, and at least one flange spaced apart from the outer panel and facing at least one peripheral portion of the inner panel and configured to prevent movement of the at least one peripheral portion of the inner panel towards the outer panel. The first panel is configured to press the at least one peripheral portion against the at least one flange responsive to pressure generated by an arc flash to form a seal between a periphery of the inner panel and the at least one flange that impedes passage of arc flash gases.

Abstract: A switchgear unit includes an enclosure having a first compartment and a second compartment and a fuse assembly mounted on a wall that separates the first compartment and the second compartment, the fuse assembly comprising a fuse housing disposed in the second compartment and accessible from the first compartment via an opening in the wall. The fuse assembly may include a cover configured to separate a fuse in the fuse housing from the first compartment and that is removable to provide access to the fuse from the first compartment. The fuse assembly may further include a power input terminal supported by the fuse housing and accessible from the second compartment and a switch disposed in the first compartment and configured to electrically connect the power input terminal to the first fuse connection terminal.

Abstract: An enclosure including a top surface, a bottom surface, a rear surface, sidewalls, and a door configured to open and close. The top surface, the bottom surface, the rear surface, the sidewalls and the door, when closed, define an interior area. The enclosure further includes at least one barrier assembly attached to at least one of the top surface, the bottom surface, the first side surface and the second side surface in the interior area. The at least one barrier assembly includes a barrier member including a substantially planar barrier portion disposed substantially parallel to one of the top surface, the bottom surface or the sidewalls and a spring assembly attached to the barrier member and configured to bias the barrier portion in a direction of the door.
