Can I Use Rebar as a Grounding Rod? Considerations & TIPS

Can I use rebar as a grounding rod?

Rebar can be used as a grounding rod, but it risks corrosion, and therefore should be encased in a protective covering.

Concrete and tubing can be placed around the rebar to act as a protective casing.

Some materials and tools will work better and last longer as a grounding rod than rebar does, so we’ll explain some of these great alternatives in the continued article below.

Can I Use Rebar as a Grounding Rod

Can I Use Rebar as a Grounding Rod
Rebar used as a grounding rod is subject to corrosion so requires specialized encasing and enough contact with the ground to be effective. 

Rebar can be used as a grounding rod, but this material is prone to corrosion so it may not be the best option for an outdoor electric fence.

There are a variety of materials that can be used as grounding rods.

But, we recommend looking in the owner’s manual of the product that you purchased to verify there is not a specific material they recommend using. 

Grounding rod materials include:

  • Rebar
  • Copper
  • Steel (galvanized, stainless, or copper bonded)

When it comes to electric fencing, steel may be the best course of action for grounding.

Rebar and copper are easily erodible materials that will not last as long outside as steel would.

What is the Minimum Depth for a Grounding Rod?

A grounding rod needs to comply with the electrical coding regulation, which is 8 feet long.

For electric fences, the grounding rod should be no less than 4 feet long and buried in the ground accordingly.

You will want to drive the grounding rod all the way into the ground, which can be difficult at times if the soil is too dry and compacted.

Dampening the ground if this happens is a great way to make it a little easier to push the rod into the soil as needed.

What Happens if You Don’t Ground Electric Fences?

What Happens If You Don’t Ground Electric Fences
When an animal touches the electrically charged fence wire, the animal feels the electric current as the charge passes through the body.

Electric fences that are not grounded simply will not work.

Without a grounding rod, the fence will not shock or correct a pet when they attempt to cross the boundary.

If you have grounded your fence with the appropriate material and size, but your fence still is not working, you may need to add more grounding rods.

Keep in mind that the grounding rods should be evenly spaced with 10 feet in between each rod.

We recommend reading the operation manual for the fence system that you purchased to verify the correct amount of grounds needed for proper function.

Manuals can be found online by searching the product name + manual.

  • Install a battery in the computer collar receiver
  • Set the boundary on the transmitter
  • Walk the boundary with the collar in hand
