How deep should a ground rod be driven?

In general, grounding rods put in vertically need to be about 8 feet deep into the soil, or, if in a very rocky area, about 2.5 feet deep when installed horizontally. In some areas, such as those with very sandy “soil” at the top layer, the rod may need to go deeper to be effective since it needs to connect with soil.
