ELECTRICAL JUNCTION OR OUTLET BOX

摘要

The present invention is an electrical junction box of the type having side portions, a back portion, and an open face portion. A flange extends completely around the side portions. This flange is located sufficiently behind the open face of the box to leave a part of the side portions projecting forward of the flange. The projecting portion normally is equivalent in length to the thickness of the gypsum sheetrock or other wall facing material being used. At least one wire or cable inlet extends outward from the side portions behind the flange for admitting electrical wiring into the junction box. These inlets will normally have a plurality of generally tubular apertures entering the interior of the box. Each aperture is originally sealed with a readily removable press-out diaphragm. In use, the box is mounted in a wall space to be covered with gypsum board or similar product so that the open face is essentially flush with the room-side surface of the gypsum board and the flange generally bears against the opposite side of the gypsum board. The flange and wire inlet apertures serve as caulk receiving surfaces to create seals and prevent air interchange between the room and wall space. Preferably the wire inlet apertures are angled forward to improve access for caulking. The flange is particularly useful in sealing the outlet box to a polyethylene vapor barrier.
