An arrangement of anodes, cable and backfill either in deep holes or distributed, the ground bed is designed to satisfy current distribution requirements of the protected structure, and other application specifications. Anodes in the ground bed connect to test stations, junction boxes, and the rectifier or solar power impressed current cathodic protection (ICCP) system, to impress the required current for preventing or controlling corrosion. Impressed current system anodes may be graphite, high silicon cast iron, or wire coated with platinum, niobium or mixed-metal oxide.
