We’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 fence. Some put disclaimers of single wire clean fence and multi wire fence with some vegetation/grass on it.
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 earlier 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 as well. 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 keeping the wire together in case an animal breaks a wire loose from one end, at least it’s still tied together at the other end.
These other thing you could do is have a ground return system. You could alternate with the 5 wires, 3 hot wires and 2 ground wires or 2 hot wires and 3 ground wires, in any pattern you want. You’ll still jumper the hot wires together with each other from top to bottom and do the same with ground wires. You then take a single wire and jumper it from one of the ground wires and connect it to the last ground rod.
So now what happens is that you still have one BIG 2 mile run, but you now have a ground return system. If an animal comes in contact with both a hot wire and one of the ground wires, they’ll get the FULL BLAST from the charger. The animal could be floating in mid air, come across both wires and still get shock of a lifetime.
Both of these set ups would work well for any set up, big or small. This is a way to run more hot wire without stressing the fence charger out.
