Wire Gauge Selection for Electric Fencing
Electricity travels through and over the surface of wire. This is important to know when selecting a gauge of wire for your electric fencing system. If a wire is larger in diameter, it has more surface are over which the electricity can travel. The more surface area, the less resistance. Using the largest diameter of wire available will transmit the greatest amount of electricity.
Most electric fences use 14 or 17 gauge wire depending on how long the fence is and what animal is being contained or repelled. Keep in mind that the lower the gauge of wire, the thicker the wire will be.
There are different types of wire: steel, aluminum, high tensile, polywire, polyrope and polytape. Each wire type has it's own purpose. Your selection will depend on the type of fence you are installing, how long the fence will stay in place, and what type of animal you are containing.
