Abstract: A disconnect having a switch mounted within an enclosure is presented. The enclosure comprises a base including a rear wall, and first and second sidewalls extending generally perpendicular from opposing side boundaries of the rear wall. The rear wall and first and second sidewalls define an interior compartment of the base for mounting the switch therein. The enclosure further comprises a cover sized to enclose the interior compartment. At least one pair of opposing protrusions extend inwardly from each of the first and second sidewalls. The pair of protrusions abut against opposing ends of the switch to restrain movement of the switch in a generally perpendicular direction and a laterally upward direction to the rear wall of the enclosure, when the disconnect switch is mounted in the disconnect enclosure. A retaining device, e.g., a ground terminal, abuts against the switch and is secured to the rear wall of the enclosure to restrain movement of the switch in a laterally downward direction.
