About this detail

A three-inch galvanized steel channel stands upon a one-half-inch by eight-inch square galvanized base plate anchored to a four-inch concrete curb or equipment pad using four three-eighths-inch by five-inch stainless steel expansion bolts with leveling nuts and a one-inch minimum grout layer. A one-quarter-inch minimum galvanized steel plate measuring six inches by eleven inches is welded to the top of the channel with three-sixteenths-inch fillet welds, providing a mounting surface sized to suit the control station and conduit feed. A separate assembly mounts a three-quarter-inch stainless steel cast box with a twenty-amp, 120-volt, two-pole, three-wire receptacle and stainless steel duplex cover plate atop a one-inch support conduit connected via a conduit union. Hardware is specified as galvanized for interior, dry locations and stainless steel for all outdoor, wet, or corrosive locations.
