Abstract: An electrical device includes a housing with a flange. The flange has a top side, an opposite bottom side, and an outer side extending between the top and bottom sides. The flange defines a bolt aperture extending from the bottom side towards the top side. The flange includes a nut retention slot within the flange. The nut retention slot has a size and shape configured to receive a nut therein through an opening along the outer side of the flange. The bolt aperture is positioned relative to the nut retention slot to align with a threaded central bore of the nut disposed within the nut retention slot to allow insertion of a bolt through the bolt aperture into the threaded central bore of the nut.
