How To Place A Grounding Rod

By Martha White


Protecting your home or shed from electrical surges and lightning strikes is important. Using a grounding rod is needed for this to work properly. It is easy to install, though it does take a bit of effort and some special tools. There may be specific rules in your area on how and where they need to be installed, so be sure to check with a local utility company. It is also very important to have them come out and mark where other lines are to avoid electrocution or damaging other lines.

First, you need to gather the equipment needed. This will include a shovel or post hole digger, a driving tool, hammer or mallet, and the proper type of rod. They are eight feet long and usually made of copper. Ask your hardware store to point you to the right type of rods for the job. Using the wrong material will not protect your home from a surge.

Next, start digging the hole. It is important to mention again that the utility company should mark the locations of other wires so you can safely dig before starting. You will also need to select a spot near the electrical panel on the outside of the house. If you are too close to the building you may reduce its effectiveness. Being placed one to two feet away is about right, but not a requirement.

Next, start digging. If you have the post hole digger, you can use it to get a few feet down. These are better than shovels because you do not need a wide hole, but a deep one. If you only have a shovel it will do, but the hole won't be as deep. Either way, you will get a good start and be on your way.

After you reach as far as you can go, add some water to the hole. You don't have to fill the hole, just make it moist so you can begin pushing the rod in by hand. The water will help with this process. As you go deeper with the pole, add more water to help out. You can move the pole back and forth with the pointed end in the ground to make it easier. Once you reach the point it won't go deeper by hand, grab another tool.

The pole driver works best. It is designed to fit over the pole, making it easy to pound it into the ground without using a hammer, which can miss and hit your hand. If you don't have one, use a two by four or other board to give yourself a larger surface to hit. Keep pounding and driving the pole into the ground until it is just above the hole.

Now you want to attach a ground wire. This will also be attached to your electrical panel, so be sure to handle with care. Some are shielded wires, so you will need to cut the end and expose the copper wire. Use a special clamp to connect to the pole. Make sure there is enough slack in the wire that bumping it will not disconnect it from the rod. You may want to dig a small trench to bury the wire it if is in an area that will be mowed and away from the house a few feet.

The last step is to fill in the hole. If you have it completely under the ground or exposed by an inch or so, pack the dirt in so it will be protected. Make sure it is low enough that a lawn mower will not hit it with the blades.
