Testing a Two-Wire Raccoon Fence Around Sweet Corn with a Voltage Tester: Wires at 5 and 12 Inches, 2,000 Volts at the Far Corner, and Splitting the Wires to Find the Short

Run two hot wires around the corn patch, one 5 inches and one 12 inches above the soil, and read both at the corner farthest from the energizer. Hold at least 2,000 volts there every evening the corn is near picking; if the number falls, unhook the low wire first, because grass under it causes most drops. How many volts does an electric fence need to keep raccoons out of sweet corn? Aim for at least 2,000 volts on both wires at the far corner of the patch. Raccoons sit in the nuisance-pest group that needs 1,000 to 2,000 volts, so the top of that range gives you a margin for dew, weeds, and a weakening battery before the ears ripen. Zareba's voltage minimums by animal list 1,000 to 2,000 volts on the fence line for nuisance pests and note that smaller animals need closer wire spacing. Predators such as coyotes sit much higher, at 4,0...
