How To Install A Grounding Rod

By Martha White


It is important to have your house or permanent structure properly grounded if you have electricity in the building. This can help prevent a fire should lightning strike or some other electrical surge be sent towards the building. Installing a grounding rod properly is very important but also much easier than you might think. There are some regulations in areas on what the requirements are, so be sure to check and see what the rules are in your area. You will also want to ask your utility company to mark where any underground lines are so you avoid hitting them when installing the rod.

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.

With the spot selected you can begin to dig. If you have a post hole digger, you can dig a couple of feet down easily. Using a shovel is fine, but you do not need to dig a wide hole. Dig the hole as deep as you can before moving to the next step.

Once the hole is deep enough to start, add water. This will help soften the soil and make the rest of the job a bit easier. Place the rod in the hole and start pushing it around. One end should be pointed and this is the end that goes into the ground first. As you push it, you may add more water to help soften the dirt even more. Eventually, you will need to use a mallet, hammer or driver to complete the job of putting the rod all the way into the ground.

After you have the rod a couple of feet into the ground, start hammering. There will be a point where it just won't go in manually anymore. If you do not have a driver, which is placed over the top of the rod allowing you to easily drive it in, you can put a board over it to make a bigger surface to hit. Keep hammering and driving it until there is just an inch or two sticking above the top of 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.

Fill in the hole and finish the job. Some areas require the rod to be completely underground and others don't have a rule. It is best to keep it low enough that the lawn mower won't hit it. If it is in an area that will be mowed, it is a good idea to bury the connecting wire as well as the rod completely under the ground.
