Ground rod

A ground rod is the most common type of electrode used for the grounding system. It provides a direct connection to the ground. In doing so, they dissipate the electric current to the ground. The ground rod significantly improves the overall performance of the grounding system.

Ground rods are applicable in all types of electrical installations, as long as there is you are planning to have an effective grounding system, both at home and commercial installations.

Ground rods are defined by specific levels of electric resistance. The resistance of the ground rod should always be higher than that of the grounding system.

Even though it exists as a unit, a typical ground rod comprises of different components which are steel core, and copper coating. The two are bonded through an electrolytic process to form permanent bonds. The combination is perfect for the maximum current dissipation.

Ground rods come in different nominal lengths and diameters. ½” is the most preferred diameter for the ground rods while the most preferred length for the rods is 10 feet.
