A precast or cast-in-place concrete transformer pad measures seventy-six inches in length, fifty-four inches in width, and thirty-six inches in total height. Four-inch thick walls and a six-inch thick top slab feature a three-quarter-inch chamfer at the edges. Multiple knockouts including seven-inch by thirteen-inch and thirteen-inch by twenty-four-inch openings accommodate utility conduits, alongside embedded lifting inserts. Section A-A and Section B-B specify internal vertical clearances of thirty inches and fourteen inches respectively, with detailed bottom openings and slab thicknesses. General notes require a concrete compressive strength of four thousand PSI at twenty-eight days, compliance with electric company provisions, and protection by bollards.
