About this detail

A precast concrete pad designed to attain a compressive strength of 3,000 psi in 28 days features a light broom or wood float finish and a three-quarter-inch chamfer on all exposed edges. The reinforced concrete pad incorporates number four reinforcing bars spaced at twelve inches maximum in each direction, along with additional corner reinforcing bars conforming to ASTM A615 Grade 40 minimum. Galvanized steel inserts measuring seven-eighths-inch in diameter with unified national coarse threads and a two-and-a-quarter-inch inside depth feature temporary plugs and sufficient strength to lift the pad. A three-quarter-inch diameter by eight-foot-long copper ground rod connects via a rod clamp to a solid bare copper ground conductor. The plan view and section A-A provide complete dimensional layouts including primary and secondary conduit openings, pad thickness, and clearances.
