How To Properly Install 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.

The first step is to get the right equipment for the job. You may need a post hole digger, shovel, and post driving tool for this job since the rods are usually eight feet long. They are often copper. When you buy one, make sure it is approved material or it will not properly ground your home. This can lead to a very dangerous situation.

The next step is to dig the hole. Avoid rocky areas or any places that the utility company marked for other lines. The spot you pick should be between one and two feet from the building for it to work the best. If it is too close, it can reduce the effectiveness by putting the surge back into the building.

Once you have the spot selected, begin digging with the post hole digger. If you do not have one, a shovel will do the job just fine. You do not need to dig a wide hole, just as deep as you can.

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.

Once it is a few feet in the ground, grab the other tools to get it to go the rest of the way. The best is a pile driver. This is designed to fit over the pole and allow you to push it in with less effort by lifting and slamming it back down onto the pole. If you do not have one, you might use a two by four to make the surface easier to hit with a hammer or rubber mallet. Hammer the pole until it is either a couple of inches above or level with the hole.

At this point, you will need to attach the ground wire. Some might want to solder it, but the best option is to have a copper clamp designed for this job. The end of the ground wire should be exposed. Make sure to give it some slack so if the wire is hit or bumped it won't pop loose from the clamp.

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.
