About this detail

An indoor floor-mounted electrical equipment base is constructed on an existing floor with a new floor finish, incorporating conduits rising through the slab and pad. Two half-inch diameter anchor bolts with hex nuts and a quarter-inch by two-inch square washer welded to the bolt head are cast into the concrete, spaced a minimum of every twenty feet or per manufacturer recommendations. The housekeeping pad features a three-quarter-inch chamfer at its edges, a minimum three-inch edge distance to the enclosure front, and manufacturer-recommended wall clearance. Reinforcement includes number four U-bars at two-foot centers in the top layer and number four U-bars at six-inch centers, secured with five-eighths-inch bolts and expansion anchors at two-foot centers.
