The basic components of a cattle electric fence kit are a power energizer, an electrical wire and insulators. The power energizer converts battery or plug-in AC power into a brief high voltage pulse that travels along one terminal of a bare wire and is connected to a metal rod implanted in the ground, called a ground rod. If an animal touches both the energizer and ground rod during a pulse, the circuit is completed and the animal receives a shock. The amount of charge needed to cause the animal a shock depends upon the size and strength of the animal, and the voltage level of the pulse that is produced by the power energizer.

To connect the wire, unspool the strands of wire, and carefully hang it on T-posts or wooden corner posts at an equal height around your boundary. The wire should be parallel to the ground and at a minimum nose-level of your cattle (or horses). A higher fence height may be required for bulls or other aggressive animals, or for your own safety when you are working with them.

A good quality grounding system is critical for a safe and effective fence. Use a digital voltmeter such as the Dare #2411 and extend the lead wire from the meter to each ground rod. Check the voltage at these locations, and add more rods as necessary until you have a reading of 300 or less volts at the furthest point from the energizer.
