Abstract

Moisture-resistant flange structures and side assemblies are for an outdoor electrical enclosure adapted to be mounted in an opening, for example, in the wall of a building. The moisture-resistant flange structures include flange elements disposed on side members of the outdoor electrical enclosure without having an aperture extending through the flange element and not having a passageway extending between the flange element and the side member into the opening. The moisture-resistant side assemblies include at least one adjustable generally L-shaped flange element coupled to the first and second side members by fasteners extending through elongated apertures in the adjustable flange elements. Extensions coupled to the side members overlap a portion of each side member and a portion of at least one of the at least one generally L-shaped adjustable flange elements and the elongated aperture extending therethrough.
