Twisted wire is nothing more than two regular boundary wires twisted together. When you have two wires this close together, it creates a dead zone, allowing the dog to safely cross over without getting any correction. However, twisted wire can only be used in specific situations. Twisted wire can only be used as a connector. You use it to connect the boundary loop to the transmitter. In addition to this, you can use twisted wire to connect one loop to another.
*You absolutely cannot use twisted wire as part of your main loop!
Sample Layouts
Imagine that you had a boundary circling your entire property, with the transmitter located inside of your home. You have everything connected and you test to make sure that everything works, but your layout is not ideal.
This means that you would have 2 strands of wire coming into the transmitter. This would not be ideal because the dog could not cross this section of the wire. Twisted wire would solve that problem.
Cut the boundary wire where it turns in from the boundary towards the house and disconnect the wire from the transmitter. (If you have pre-twisted wire, you would replace this section with it. Skip straight to step 5 where the twisted wire is connected up.) If you don’t have twisted wire, you will need to twist it yourself.
Begin twisting the 2 wires together, about 1 twist per inch. It is better to have more twists than less. Many people find it easier to attach them to an electric drill and let it twist the wires for you.
Next, splice the twisted wire back into the boundary loop on one side, and splice the other side of the twisted wire on the other side of the boundary loop. Reconnect each side of the twisted wire to the transmitter in your house.
Very good! Now your dog can safely cross over the twisted wire without hearing any beep or getting any correction.
Note: Do you need to cut your wires and splice in your twisted wire? The answer is no, you don’t have to. You can simply twist together your two boundary wires going into your transmitter, if you want to avoid splicing your wires together.
