Reduce the risk of lightning damage by using a single-point grounding system. In
this system, all ground lines terminate at the same point—the primary earth
ground. This point normally is the main utility ground installed by the utility
company to provide a ground for the house wiring (see Figure 2-4). This ground
usually consists of a copper rod driven 1.5 to 2.5 meters (6 to 8 feet) into the earth.
