Designed for Small Properties

The Gallagher M20 is best suited to small, well-maintained electric fences. Typical applications include lifestyle blocks, horse yards, small livestock paddocks, garden protection and pet containment.

The unit provides continuous power when connected to a suitable 240V outlet, removing the need to recharge or replace batteries during normal operation.

Understanding the Fence Distance Rating

The advertised 2km rating represents a clean fence operating under ideal conditions. Gallagher’s more practical recommendation is approximately 0.5km of multiwire fencing, depending on the fence design and operating environment.

Vegetation touching the live wires, damaged insulators, poor connections and inadequate earthing can reduce the effective fence distance. Select a larger energiser if the fence is likely to experience significant vegetation or future expansion.

Safe Mains-Powered Installation

The Gallagher M20 must be installed in a dry, protected and well-ventilated location near a suitable 240V power outlet. Follow the supplied instructions and keep the power connection protected from rain and moisture.

Use high-voltage insulated cable between the energiser, fence and earth system. Position the electric fence earth away from household electrical earths, telecommunications equipment, water pipes and other utility earth systems.

Is the Gallagher M20 Right for Your Fence?

The M20 is a practical entry-level energiser for small properties with short, clean electric fences. It is suitable for customers who have access to mains power and require a simple unit for light-duty animal control or property protection.

For longer multiwire fences, heavier vegetation or expanding livestock systems, choose a larger energiser with additional stored energy. Correct earthing remains essential regardless of fence length.
