The fence energizer must provide a high guard voltage on the charged wires to force the shock current to jump from the wire to the animal’s skin. the fur, hair, or wool of the animal insulates the wire from the animal’s skin. a guard voltage of 5000 volts will jump through about 1/8 inch (3mm) of hair. domestic cattle can usually be managed with a guard voltage of approximately 2000 volts (horses and pigs can be managed with slightly lower guard voltages).
