The assembly consists of a three-quarter-inch by ten-foot galvanized steel ground rod installed in a formed depression in concrete. The rod is either a single piece or joined with a threaded-on shepherd's hook. Connections include a compressed copper sleeve and an exothermic weld, with connections to pits made only where required. The top view details an eighteen-inch diameter marker with a yellow center, a red border, a central grounding point, and painted text indicating the word "GROUND" in one-inch black letters and the test date in half-inch black letters.
