Splicing the Wire

Laying Out the Dog Fence Wire

Now that you have installed your transmitter box and ran the first parts of wire from the box to the outside, it is time to lay out your wire. You will need to lay the wire above the ground and connect it to the transmitter box. This will help you to make sure everything is working properly. Look at the design that you wish to lay out. Run the wire above the ground in the location where you plan on burying or mounting it. Following your plan, be sure to use twisted wire or boundary wire. In order to leave yourself plenty of extra to work with, you will need to allow about 20% more extra wire. 

Splicing Your Dog Fence Wire

Now that you have placed all of your dog fence wire, you need to go back and splice together all of the sections. To do this, just strip off about ½ inch of the insulation covering. Insert the stripped wires into a waterproof wire nut, which you can purchase at your local hardware store. Twisting the wire nut will join the wires tightly. Be sure to not join them too tightly or you may risk snapping a wire.

Materials

Those who install Invisible Fences® professionally use a waterproof dog fence splice that is filled with dialectic grease and silicone. The reason you need a waterproof splice is so that you can prevent the wire from damage and corrosion. It is also important to use the right slices so that you can protect the dog fence splice area from electrical surges. Crimp splices create a choke at your connections and can cause the spliced area to short out.

Avoid Crimp Splices & Solder Joints

Using crimp type splices is not recommended. Solder joints are also not recommended to make the splices. This is because it creates a choke point in the spliced area. Surge damage can then cause the spliced area to disintegrate if lightning strikes or if there is a ground spike.

Wire Strippers

A pair of wire strippers is needed to splice your twisted wire and perimeter loop wire at connection points. A common tool, these can be purchased at any hardware store.

How to Splice Electric Dog Fence Wire

You will need to know how to splice dog fence wire when you initially install your system. It is also something you will need to know in case your wire ever breaks on you. It is quick and easy to splice wire as long as you have the right tools.

  1. There should always be at least 6 inches of slack wire on each end of the wires you are splicing.
  2. Take the wire cutters and strip about 1” of the covering from each end of the two wires being spliced.
  3. Take the two exposed copper wire ends and twist them together.
  4. Cut part of the end of the exposed copper off, leaving only about ½ of an inch. 
  5. Take a wire and hand tighten it on the exposed copper ends.
  6. Take the wire nut and insert it into the wire splice connector. 
  7. The wire nut should be pushed all the way to the bottom of the waterproof tube to make sure that no water can reach it.
  8. Take one wire through the divots on each side of the connector. Snap the lid closed in order to seal your splice inside. 

There are three instances where you will need to use this splicing process. The first is to connect your twisted neutral wire to the main loop. The next is to connect a section of the main loop where you need to stop and start, such as crossing a driveway or changing wire spools. The third is to connect the twisted wire to a lake loop within the main perimeter.

Professional Recommendation: Be sure to always bury your splice points deeply. About 6 inches deep will suffice. This will prevent the connection tubes from working their way to the surface. 

Testing the System

Now that all of the wiring has been laid out and it is connected to the transmitter box, it is time to turn on the system and test it out. When the transmitter is turned on, you should see a green light, indicating that everything is connected and the signal is traveling around the loop. Should there be an alarm or a flashing light, you will need to investigate the problem. Go back and check all of your splices to make sure that a complete loop is formed by the wire. You will need to double check your layout to make sure the twisted wire sections make logical sense. 

After your system appears to be working correctly, turn on the collar and test the perimeter. When you approach the boundary, you should hear an audible warning tone from the collar.
