Abstract
A gasketless enclosure (10) for housing outdoor electrical equipment. The enclosure includes a box (12) having a base (14) and upwardly extending, sidewalls (16A-16D). The walls define an open, upper face, over which fits a cover (18). A closure mechanism (28) includes an upwardly projecting lip (30) formed at the upper end of the sidewalls and extending around the circumference of the box, and a channel (32) formed in the abutting face (34) of the cover and sized to receive the lip. To help prevent moisture from seeping into the interior of the box and harming the equipment housed therein, gutters (42, 44) are formed in the abutting surfaces of the box and the cover. The gutter (44) formed in the box is formed outwardly of the lip, and the gutter (46) formed in the cover is formed outwardly of the channel. The gutter in the cover sits over the gutter in the box when the cover is in place. The gutter formed along the top and sides of the box is open at the bottom of the enclosure, providing a drain (45) for directing moisture collecting in the gutters to the outside of the box.
