Energizer Sizing Recommendation

We Recommend the 1 Joule Per Mile Rule

When selecting an energizer, calculate the total miles of energized wire, not simply the distance around the pasture.

For example, a ½-mile fence with two energized wires equals approximately 1 mile of energized wire.

Vegetation touching the fence, poor connections, dry soil, and damaged insulators can increase the power requirements of the fence system.

Grounding Recommendation

Proper grounding is essential for reliable electric fence performance. We recommend approximately 3 feet of grounding per output joule as a practical starting point.

Dry, sandy, or rocky soils may require additional grounding.

Common Applications

• Rotational grazing
• Temporary electric fencing
• Cattle fencing
• Sheep and goat fencing
• Remote pastures
