Basis rods are an important part of having a safe electrical system. They create a route for stray electricity, which occurs during a brusque or other malfunction, to have an efficient route out of a building. To begin installation, you need to find an appropriate location to install them then drive them into the ground. Once the rods are in the footing, and then you demand to ensure that they are continued to the electrical system they are grounding correctly. With a bit of planning and care, you can install grounding rods for a new electrical panel or for an existing panel in gild to minimize the threat of electrical burn and injury.^[1]

1
Install the rod in a location near the electrical panel. Ground rods need to be installed in the ground outside in a spot where they can be hammered 8 anxiety (2.4 m) into the ground. There is no requirement for how shut or far from a building they should go, but exist sure to pick a spot that is convenient to become to and where y'all will have space to utilise tools to drive the rod into the basis.^[2]
- If a grounding rod is as well close to a edifice foundation, information technology could interfere with it. Because of this, it'southward best to go on it at least ii feet (0.61 m) from the side of the building.
2
Plan the route for the grounding electrode conductor. In one case a ground rod is driven into the footing, information technology will need to exist connected to the electric console inside. This is washed with a wire called the grounding electrode usher. It's important to cistron its road in when picking a spot for the ground rod. Make sure the grounding cablevision can hands be routed to the panel from where the grounding rod is positioned.^[3]
- If you have an thought of where you lot would like to drill a hole in your building to get the conductor inside, selection a spot for the grounding rod nearby.

Avert locations where the footing is generally rock or heavily compacted. Because you have to drive the rod 8 anxiety (2.4 m) into the ground, yous desire to avert areas that are excessively rocky. While you wont always be able to avoid rocks or know they are there, avoid picking an area that you know is full of rocks.
4
Locate any wires or pipes in the path of the ground rod. Once you have picked a spot to put your ground rod, you lot need to brand certain you volition not damage annihilation in the ground when you install it. In many countries, in that location are hotlines y'all tin telephone call to have your utilities located free of charge. In the US, for example, there is a national hotline that you tin call in social club to notify your utilities that you need a locator.^[4]
- It usually takes about two-iii days for the utilities to come up and do the locating, so plan ahead.
- If in that location is no locating hotline in your areas, you tin call the utility companies directly that serve the building and ask them to locate their underground lines.

1
Buy an approved grounding rod. Grounding rods need to made of specific conductive metals and they need to made to a specific length and width. Considering of this, it's all-time to buy a rod that is specifically made for this use. Buying a listed rod, pregnant it has been verified past a certification group, will ensure that your grounding rod is the correct size and material. Virtually dwelling comeback and hardware stores stock approved grounding rods. ^[5]
- High quality grounding rods are typically made of high carbon steel for it'southward durability and electro-plated with copper for its conductivity and longevity.^[six]
- In the The states, ground rods demand to exist at to the lowest degree 8 feet (2.4 m) long. If they are listed, they demand to exist at least ¹⁄_two inch (one.3 cm) wide and they will have a marker that says they are listed. If they are not listed, they demand to be at least ⁵⁄₈ inch (one.6 cm) wide.^[7]
- A listed ground rod will have a marking near the top of information technology that states that it is approved. The marker allows an electrical inspector to immediately know you accept used a proper rod.
2
Start digging a hole with a shovel or post-pigsty digger. Because a basis rod is and then long, it can exist hard to get leverage on the top of information technology when y'all start installing it. To get the top down to a more manageable level, dig a pigsty 2–four feet (0.61–1.22 m) deep. By putting the cease of the footing rod in the hole, it will be easier to get-go hammering the acme of the rod.
- If you don't want to dig a hole or you can't for some reason, you volition need a ladder or stride stool to go upward loftier enough to start pounding in the acme of the ground rod.
3
Drive the rod into the ground. Using your hammer, drill, or driving tool, gradually drive the rod vertically into the basis. You need to drive your rod all the way into the ground. The electrical code states that it must have 8 feet (2.4 m) of contact with the ground, so you demand to drive information technology all the way down.^[8]
- Driving a ground rod into the footing can take a long fourth dimension and can exist difficult piece of work. If y'all can discover someone to take turns driving the rod, information technology will make for a much easier job.
- Some electrical inspectors will allow you to leave 1–2 inches (2.v–5.1 cm) sticking upwardly out of the footing. Withal, some desire the unabridged affair covered in earth.

Pull the grounding electrode conductor to the grounding rod. Once the grounding rod has been driven into the ground, you need to connect it to the electric organisation of the building. Pull the grounding electrode conductor up to the height of the grounding rod, making sure it is long plenty to make a permanent connectedness between them.^[9]
- Give the grounding electrode a footling bit of slack, and so it'southward not extremely tight where it connects with the grounding rod. This volition ensure that if it gets hit or pushed on, it won't get dislodged from the grounding rod.
- If the grounding electrode conductor has a sheath on it, the last ^ane⁄_two inch (1.3 cm) should be cut off, exposing the wire.
2
Clamp the grounding electrode usher to the grounding rod. In that location are specific clamps that are used to connect grounding electrode conductors to grounding rods. You will need one clamp. Put the end of the conductor and the end of the rod inside of the clench and turn the screw on the clamp to press them together securely.^[10]
- These clamps are sold in home improvement and hardware stores.
3
Connect the grounding electrode conductor to the ground bus. The footing bus is where all the ground and neutral wires are attached in the electric console. To brand the connection, slide the end of the grounding electrode conductor through one of the holes in the bus and tighten the screw in that hole until it holds the wire very tightly.^[11]
- In some cases, the basis wires volition exist connected to the footing bus and the neutral wires are connected to the neutral bus. These 2 bars are and so continued with a main bonding jumper. If this is the case, you can adhere your grounding electrode usher wherever information technology fits on either omnibus.^[12]
- You demand to be very careful when you are doing any piece of work in an electrical console. Brand sure that your fingers, tools, and the grounding electrode conductor don't brand contact with the energized confined in the panel, which are located behind the circuit breakers.
- If you are unsure about how to brand this connectedness safely, rent an electrician to do the work.
