Abstract
Footing-type grounding electrodes installed in the concrete foundations of residential and small commercial buildings designed to meet a maximum ground resistance value of 5 ohms are described. Bare solid copper electrode wires of various lengths, steel reinforcing rods, and 10-foot lengths of hot galvanized rigid steel conduit were used to determine the resistance values.Keywords
