A good grounding system should maintain a resistance of 10 ohms or less to ground. Ground resistance
occurs when grounding system components, or the soil itself, oppose the flow of electricity into the
earth. The higher the ground resistance (higher ohm readings), the higher the chance the surge will
damage the equipment’s electronic components
rather than be shunted to ground. If you are unable to
reach a resistance of 10 ohms or less, you can enhance the ground network with additional ground
electrodes or plates.
All grounding rods or plates must be connected with #6 AWG or larger solid copper wire. Install the
connecting wire in as straight a line as possible. If you must make a turn or bend in the wire, make the
turn in a sweeping curve with a minimum radius of 8 inches. Ground rod corrosion will increase the
ground resistance and decrease the effectiveness of the SPD. Use the correct material for your
installation environment. Copper plated, solid copper, and stainless-steel ground rods are options to
consider. Do not use galvanized grounding rods for this application.
