Choosing The Best Grounding Materials

2. How Long Are Ground Rods?

Ground rods come in both 8′ and 10′ lengths, however, an 8′ ground rod is the common size used in residential installations. As a rule, ground rods must be a minimum of 8′ long, so do not cut them off! If you are in very dry ground, you may want to consider a special clamp that allows you to stack ground rods.

Another option is to add a second ground rod, which is a better option, but remember that the NEC requires them to be a minimum of 6′ apart. If possible, try to get the ground rods in a moist area around your home. Usually, the area close to the exterior wall has enough moisture due to runoff water from downspouts.
