Splicing The Wire | We can show you how to fix a wire break properly

Splicing The Wire


Laying Out The Dog Fence Wire

Once you’ve installed your transmitter box and run the initial bits of wire from the box to the outside you should lay out your wire above ground and connect it to the transmitter box to ensure that everything is working as planned. Working from your layout design, run the wire above ground right where you plan to bury or mount it. Be sure to use twisted wire or boundary wire as per your plan. You’ll also want to allow extra wire (about 20% more) to leave yourself plenty of margin to work with.

Splicing The Wire

Once you’ve placed all of your wire, go back and splice together the sections. To do this simply strip off about a half inch of the insulation coating and insert the stripped wires into a waterproof wire nut (found at your local hardware store). Twist the wire nut to tightly join the wires but don’t over-tighten or you’ll risk snapping a wire.

Waterproof Wire Splices

Professional Invisible Fence®  Installers use a waterproof dog fence splice filled with dialectic grease and silicone.  The main reason for having a waterproof splice is to prevent corrosion and damage to the wire. Using the proper splices is also critical to protect the dog fence splice area from electrical surges, crimp splices create a choke at your connections and can cause a short in the spliced area. Dog Fence Wire Nuts/ Dog Fence Wire Tubes are available in our online store.

Avoid Crimp Splices & Solder Joints

We do not recommend crimp type splices. We also do not recommend using solder joints to make splices. This also creates a choke point in the spliced area where surge damage can cause the spliced area to disintegrate in the event of a lighting strike or ground spike.

 Wire Stippers

You will need a pair of wire strippers for splicing your twisted wire and perimeter loop wire at connection points. These are a common tool and can be purchased from just about any hardware or big box store.











 How To Splice An Electric Dog Fence Wire

Splicing dog fence wire is not only needed when you initially install your system but is also something you'll need to know how to do in case you ever have a wire break on your hands. Splicing wire is quick and easy as long as you have the right tools on hand.

1. Always leave at least 6 inches of slack wire on each end of the wire to be spliced.

2. Using the wire cutters strip about 1" of coating from each end of the two wires to be spliced.

3. Twist the exposed copper ends of the dog fence wires together as neatly as possible.

4. Shorten the 1" inch of exposed copper to approximately ½ of an inch by cutting the end.

5. Hand tighten a wire nut on the twisted exposed copper ends.

6. Insert the wire nut into the waterproof dog fence tube (wire splice connector).

7. Push the wire nut all the way to the bottom of the waterproof tube, to ensure no water will reach it.

8. Route one wire through the divot on either side of the waterproof connector and snap the lid closed sealing your splice inside. 



You'll use this splicing process to connect your twisted neutral wire to the main loop, connect section of the main loop where you needed to stop and start (like crossing a driveway or changing wire spools), and connecting twisted wire to a lake loop within the main perimeter.  

Tip from the pros: Always bury your splice points deep. This will prevent the bulkier dog fence connection tubes from working their way to the surface. 6 inches deep is a good rule of thumb.


Testing The System

Now that you have laid out all of your wiring and connected it to the transmitter box you’re ready to turn on the system and test it out. When you turn on the transmitter you should see a green light indicating that everything is connected and the signal is traveling around the loop. If you get an alarm or a flashing light you’ll need to look for a problem. Go back and check all of your splices and make sure that your wire forms a complete loop. Double-check your layout to make sure your twisted wire sections make sense.

Once your system seems to be working properly, turn on a collar and test the perimeter. As you approach the boundary you should hear an audible warning tone from the collar.

If you do encounter a problem be sure to disconnect your system before heading out to play with the wire.
