5.3 All-Live Wire, Earth Return System
The Earth Return (also called Ground Return) configuration is the most common method of
configuration for electric fences, particularly smaller fence applications like strip grazing. The
fence live wire(s) are electrified and rely on the soil to complete the circuit back to the energizer
earth Terminal when an animal touches the fence.
The electrical circuit
is closed between
the fence and the ground
when the animal touches the fence
The circuit is closed
when the animal nudges
both the live and earth wires
of a fence
A good circuit requires adequate current flow through
the ground (through moist soil)
5.4 Live-/Earth-Wire Fence Return System
The live-/earth-wire fence return configuration for electric fences is used where the soil is too dry to
complete the circuit adequately, or the animals are likely to try to force their way through between
the fence wires. in this system earth wire(s) are also run along the fence with the live wire(s) to
provide a low resistance path for the current to return to the energizer. in this system if the soil is
moist enough it will also function as a return path for the current when the animal touches the live
wire, but if the soil is not moist or has poor conductance, this system will keep your fence effective
provided the animal touches both a live and the earth wire simultaneously.
