15. Best Practice

16. Driven rods are relatively inexpensive to purchase, however ease of installation is dependent upon the
type of soil and terrain where the rod is to be installed. The steel used in the manufacture of a standard
driven rod tends to be relatively soft. Mushrooming can occur on both the tip of the rod, as it encounters
rocks on its way down, and the end where force is being applied to drive the rod through the earth.
Driving these rods can be extremely labor-intensive when rocky terrain creates problems as the tips of the
rods continue to mushroom. Often, these rods will hit a rock and actually turn back around on themselves
and pop back up a few feet away from the installation point.
Because driven rods range in length from 8 to 10 feet, a ladder is often required to reach the top of the
rod, hi h a e o e a safet issue. Ma falls ha e resulted fro perso el tr i g to literall ha k
these rods into the earth, while hanging from a ladder, many feet in the air.
The National Electric Code (NEC) requires that driven rods be a minimum of 8 feet in length and that 8 feet
of length must be in direct contact with the soil. Typically, a shovel is used to dig down into the ground 18
inches before a driven rod is installed. The most common rods used by commercial and industrial
contractors are 10 ft in length. Many industrial specifications require this length as a minimum.
A common misconception is that the copper coating on a standard driven rod has been applied for
electrical reasons. While copper is certainly a conductive material, its real purpose on the rod is to provide
corrosion protection for the steel underneath. Many corrosion problems can occur because copper is not
always the best choice in corrosion protection. It should be noted that galvanized driven rods have been
developed to address the corrosion concerns that copper presents, and in many cases are a better choice
for prolonging the life of the grounding rod and grounding systems. Generally speaking, galvanized rods
are a better choice in all but high salt environments.
An additional drawback of the copper-clad driven rod is that copper and steel are two dissimilar metals.
When an electrical current is imposed, electrolysis will occur. Additionally, the act of driving the rod into
the soil can damage the copper cladding, allowing corrosive elements in the soil to attack the bared steel
and further decrease the life expectancy of the rod. Environment, aging, temperature and moisture also
easily affect driven rods, giving them a typical life expectancy of five to 15 years in good soil conditions.
Driven rods also have a very small surface area, which is not always conducive to good contact with the
soil. This is especially true in rocky soils, in which the rod will only make contact on the edges of the
