Splicing the Cable

In most installations you will need to join sections of cable.  To do this, just strip half an inch of insulation off each wire.  Then use a waterproof wire nut to connect the two wires.  It is important that you use a waterproof wire nut since the wires will be buried outside.  If you don’t the system can short out every time the grounds gets wet. 

Try to place the join in a spot that does not get waterlogged, so stay away from gutter downspouts and the like.  This will help prevent the system shorting out every time it rains.

It is important that you use actual waterproof wire nuts.  The weatherproof wire nuts have a lid and are filled with gel to protect the spliced wire from water infiltration.  You can get waterproof wire nuts at most larger hardware or electrical supply stores.  For example Home Depot stocks the Ideal -WeatherProof Wire Connector” (available only instore).    Waterproof wire connectors are cheap and will set you back less than a dollar a piece.

 To join the two sections of wire, simply strip the half an inch of insulation off the end of each section or wire, and insert the stripped end into the wire nut.  Now gently twist the wirenut until the wires become firmly joined.  (you will feel gentle resistance)  Overtightening will snap the wire and undertightening will result in a poor join.

how do you hook up the wire to the box using the single wire

ADMIN – Hi Robert,

To connect the wire to the transmitter (control) box, you strip a bit of insulation off the end of each wire, then insert the wire into a little terminal block in the transmitter box. There are two holes, one for each wire.

Can you buy extra wire at Home depot that would work with the IUC-4100? See site for the wire specs on item # 100349920.

Thanks in advance!

ADMIN – Hi John,

Some Home Depot’s and Lowes sell PetSafe boundary wire, which is compatible with the Innotek systems. It costs about $25 for 500 feet. You can also get flags, which you will need to mark the boundary (they are in the plumbing section and usually used to mark utility lines), and you can also get waterproof wire nuts for splicing the wire.

Generally speaking, you can use any insulated single copper wire. It deos not matter if it is twisted or stranded. Preferably, get a wire that is rated for direct burial, it is going to hold up much better in the ground. (i.e. don’t use wire intended for wiring the interior of a house – you want something intended for outdoor burial)

hi, having trouble and need help ! someone hit my fence where all the wires come together, my question is , do i tie ALL of my wires together at this point ie; the 2 twisted from power source and the 2 ends around property ?

ADMIN – Hi Jim,

Each twisted wire should connect to only one of the boundary wires. When installing a dog fence, all splices should be 1-to-1, there are virtually no situations where you need to splice three or more wires together.
