![]() ![]() If you have concerns about your business or home grounding, contact a licensed electrical contractor. If you do not provide proper grounding in accordance with the NEC, there is no way to mitigate electrical damage that may occur beyond your electrical panel. Unfortunately, we have no control over how well your electrical panel is grounded. If soil conditions change due to drainage or other factors that affect soil moisture, a ground rod that was acceptable at the time of installation may no longer meet approved requirements. Ground rods that are installed in rocky or dry soil should be checked to make sure they still have a low resistance. Ground rods that are bent over, have disconnected wires or are severely corroded must be replaced. This reduces the effectiveness of the ground. Rods that are not fully installed may extend a foot or more above the surface of the soil. In some cases, problems with ground rods are easy to see. However, sometimes ground rods extend a few inches above the surface, making it easy to inspect the connection. The tops of the ground rods are typically below the surface and may not be easy to inspect. Below the surface, the wire is connected to one or more ground rods. Typically, this is a copper wire about one-fourth-inch in diameter and can be seen going down into the soil. Causes of damage include corrosion, freeze/thaw cycles, landscaping equipment or careless installation of grounds for other equipment, such as cable TV, security systems or generators.Ī visual check of grounding can be done by inspecting the wire that connects the electrical panel near the meter to the ground rod. Ground rods and their connections to your business or home’s electrical system may be damaged over time and must be properly maintained. Ground rods are simple and inexpensive but are crucial to protecting your electric equipment and appliances. ![]()
