Need a top-notch connection of ground wire to ground rod? We have the product for you!

The Fi-Shock® Ground Rod Clamp helps to make a superior connection of ground wire to ground rod. It's heavy duty construction ensures long usage. Packed 1 clamp per bag.


One Wire System

The one wire system means that there are only "hot" or charged wires running the perimeter of the fence. One wire systems are often used for smaller areas -- areas with only one or two strands of wire. Often a hot strain of wire is run along the top of a barbed or woven wire fence to keep the livestock from reaching over the fence.


Two Wire Systems

A two wire system is a great way to help the animal complete the circuit by touching the “hot” and a ground wire at the same time. The two strand system is used when there are multiple (3 or more) strands of wire and the wires alternate between charged and grounded wire. The idea is that the wire is alternated between “hot” and ground wire on the fence: one “hot,” the next ground, the next “hot,” etc.

This is most often used for large areas and has the benefit of increasing the chances of the animal touching a charge and a ground and thus completing the circuit. Additionally, the two wire system is ideal for areas with sandy or rocky soil. This system is also well-suited for animals with long hair or wool.

For these electric fence systems, the grounded wires will be connected directly to the grounding rod(s) or the grounding terminal on the fence charger, and the charged wires will connect directly to the fence terminal.

Proper Grounding

Completing the Circuit

For proper grounding, the electric fence charger will need to have one terminal connected securely to the wire and the other terminal connected securely and completely to the grounding rod(s).

If the grounding system is poor or insufficient, electricity cannot complete a path to the charger, and as a result, little or no shock is given. An animal completes this path when it touches the fence wire and the earth ground simultaneously.

The electrical charge passes through the animal into the earth and back to the grounding rods. The grounding rods are connected to the ground terminal of the charger. When this circuit has been completed, the animal will receive an electrical shock. Click on image to enlarge

For most electric fence systems with dirt or moist soil, one 6-8 foot grounding rod will be sufficient. However, rocky, sandy and dry soil may require multiple grounding rods placed 10 feet apart to completely create a circuit. Also, longer electric fences often need better grounding systems, so in these cases, multiple grounding rods may be needed as well.

For the smallest electric fence systems such as those used around a garden or flower bed, a two foot grounding rod is often sufficient to allow an animal to complete the circuit.
