Wire return fence
Author: Lawrence

I have a 46 inches tall, low tension electrified seven strand fence. I have a big energizer, speedrite 12i and have 8000 volts average almost all the time. I have six, 6 foot ground rods for the energizer. I need to control goats and dogs.

My northern Minnesota soil is always moist and my ground is good but the soil freezes very deep up to six feet but not so deep this year. After recent snows the two bottom strands are covered with snow so I hooked them up to two six foot ground rods making it a wire return fence for the time the snow is on the ground at least.

I also grounded the sixth wire, second down from the top. I figure that I would want to have more hot wires than grounded ones anyway but am not absolutely confident on the detail of which wires to ground.

It is my understanding that the wire return may be more effective than a earth return when the ground is frozen especially for smaller animals with hooves. Is that your opinion?

Which of the other wires, if any, would you ground in my situation?

Lawrence,
Snow is the bigger problem when it comes to grounding. It acts as an insulator between the animals and the soil. Hooking some of your wires to ground rods during the winter months is a good idea. What you have done sounds good. The only other wire that I might recommend hooking to the ground rods would be the 4th wire from the bottom so that they are alternating. This way if you have an animal try to climb through the wires you are ensured a good ground contact.
