Installing a grounding rod for an electric fence system is a crucial step in ensuring that your fence is functioning at its maximum potential. A properly grounded fence will contain livestock and keep predators out, while an improperly grounded fence will not shock animals when they come into contact with the fence.
When installing grounding rods, it's important to use a minimum of three rods spaced at least 10 feet apart. Use a fence-post digger to dig a hole, and then thoroughly and continually moisten the soil inside the hole to assist in driving the rod the rest of the way. For best results, drive the rods until they are flush with the soil.
It's important to use the right type of metal for grounding rods. The best ground rods are made from copper or galvanized metal and should be at least 4 feet long. Avoid using simple pipes or pieces of rebar as these are usually made of metals that will corrode after just a few years in the ground and cause your system to fail. Additionally, it's important to match metals when installing, clamping or connecting your ground rods to avoid electrolysis.
Checking your voltage periodically to ensure adequate grounding is important. Checking during the driest and wettest part of the year is highly recommended. To connect your ground rods to the fence charger, use a 10- to 14-guage insulated lead-out wire rated at 20,000 volts or better. If you aren't satisfied with the shock your fence is delivering, adding more ground rods can help.
Another option to create better ground in dry soil is by drilling a larger than normal hole and filling it with a bentonite after inserting your grounding rod. This gel-like substance will wick moisture, creating a stronger current. Lastly, it's important to place your ground rods away from utility poles or lines to avoid disruption of electrical or phone service.
By following these tips, you can ensure that your electric fence is properly grounded and functioning at its maximum potential. Keep your livestock and predators where they belong with a properly grounded electric fence system.
