Is Your Multi-Wire Fence Too Much For Your Charger?

I've been asked a handful of times, "Is my multi wire set up too much stress for my fence charger?" Some manufactures rate their chargers in total linear length of wire, and some rate in single/multi wire, so it can be hard to figure out. So let's look at an example: Let's say you bought a fence charger rated up to 5 miles of single/multi wire of fence. You put up 5 strands of wire at 2 miles each, making 10 miles of of electric fence. So now you're thinking to yourself, "Crap, I've got too much fence for my fence charger, now what do I do?"  Do you take down 3 of the wires and stay with 4 miles of total fence? You could, but then you just wasted all that extra time running the other wire. So what do you do? You leave all 10 miles of fence wire up and then take a jumper wire and tie all 5 wires together from top to bottom. I usually do this at both ends. Now what happens is that these wires are now parallel and they divide the resistance by 5, in theory. So you still physically have 10 miles of fence, but to the fence charger, it only feels one BIG 2-mile run of electric fence. Also by having them tied together at both ends, you have a better chance of keeping the wire together. If an animal breaks a wire loose from one end, at least it's still tied together at the other end. Another thing you could do is have a ground return system. You could alternate 3 hot wires and 2 ground wires, or make the top 2 hot wires and the bottom 3 ground wires. Just choose

One thought on “Is Your Multi-Wire Fence Too Much For Your Charger?

  1. Very helpful article. My experience with an alternating hot/ ground system in lush green grass, however, can lead to shorting out the fence with the 80 % moisture grass touching the ground and the hot wires at the same time. This system works great for short grass or dryland grazing though. Thank you for the nice article.
