Dangers involved in grounding of electrical systems to water pipes are reviewed briefly. Safety orders, municipal and state codes, technical society recommended practices, etc. are discussed in this connection. It was found that the City of San Francisco required a driven ground rod to be installed at each point where the neutral was connected to the water line.
A proposed driven ground rod test program is outlined briefly. Some 33 driven ground rods arc scheduled to be examined after burial for one, three and seven year periods. Materials to be tested include mild steel. galvanized steel, copper clad steel, Ni-Resist and Type 302 stainless steel. Copper is not deemed to have the desired galvanic properties. 7.7
