Why trust BestReviews?

A ground rod safely diverts electricity to the ground where it can dissipate harmlessly. There are different types of rods for specific jobs and soil types. Most ground rods are copper-coated or galvanized, with copper-bonded rods coming in at a lower price. Most rods are 8 feet long and are safer and more likely to be legal in your area than 6- or 4-foot rods. However, longer rods can be difficult or even dangerous to install. Most rods have a diameter of 5/8 inches, but ¾ inch diameter rods are easier to drive into the ground at the cost of higher resistance. Some rods may include a clamp to attach the rod to wires.
