About this detail

Electrical panels weighing up to four hundred pounds maximum are mounted using P-1000T Unistrut channels of required lengths secured at each corner. For concrete walls, the Unistrut is fastened with three-eighths inch diameter Hilti KB3 expansion anchors at four locations, one at each corner. For metal stud walls, backing is provided behind up to two layers of maximum gypsum board, and panels are secured using number twelve sheet metal screws from the Unistrut to the backing. Panels under two hundred pounds require two sheet metal screws top and bottom, while panels over two hundred pounds require three sheet metal screws top and bottom. Surface mounted panels may be applied directly to the face of existing walls where site conditions require.
