This is the PetSafe brand boundary wire for making larger containment areas or mending broken wire. This kit comes with a 500 ft spool of 20 gauge solid copper wire and 50 boundary flags. You are suppose to space the flags at 10' intervals during the training sessions. You remove every other flag at the end of the training course over a period of 8 days to complete the training.The dog now responds to the auditory cues from the receiver (collar) and no longer needs the visual cues from the flags.
A 500 ft. spool is suppose to enclose up to 1/3 of an acre. You may end up using more wire for special areas. Places where you would like the wire to cancel itself out, you twist the outgoing and incoming wires together in a braid to make them cancel the signal. Or if you are not making a complete square containment area you will have to run a double loop. That is where you run the wire along let's say 3 sides of a square and then keeping the wire at least 3'-5' away from itself run the wire back along the same path to the transmitter (master unit). In this fashion you can contain an area that doesn't consist of four side. Like say for instance you have land that backs up to a lake and you would like to not run a fence along the water. You would create a double loop to accomplish that. The double loop would look something like an outline of the letter C or U for example.
According to the reference charts from PetSafe, for a: 1/4 acre you will need 415 ft of wire; 1/3 acre = 480 ft; 1/2 acre = 590 ft; 1 acre = 835 ft; 2 acre = 1180 ft; 5 acre = 1870 ft; 10 acre = 2800 ft; 20 acre = 3750 ft; 30 acre = 4600 ft; 40 acre = 5330 ft; 50 acre = 5900 ft; 60 acre = 6500 ft; 70 acre = 7000 ft; 80 acre = 7500 ft; 90 acre = 8000 ft; 100 acre = 8350 ft.
8350 ft is suppose to be the max length you can run with this PetSafe 20 gauge wire. I walked the area where I wanted to install my fence and counted my steps. I knew my stride on average covered 3 feet. So I multiplied my steps x3 to determine the amount of wire I would need. In my case it was 600 steps = 1800 ft or 4 spools total. PetSafe also recommends staying away from telephone, CATV and electrical lines that may be buried in ground as they may affect the signal. If you have to cross them you should do so at 90 degrees (perpendicular) to them.
You can splice the wire together using electrical wire nuts. The kit comes with them and waterproof grease caps like the kind that are often used with sprinkler irrigation wires. You simple install the wire nut and then insert it down into a cylindrical 3" tube filled with waterproof grease. Then you fold down the cap thats on the end of the tube that has wire exit slots around it, to seal the tube. You can also use waterproof scotch locks by 3M that are often used in the telephone and security industries. You can get these at most home improvement stores in the telephone tools section. You do need special pliers to crimp the scotch locks however, but I believe this is the sturdiest and easiest way to splice these wires. You don't even have to strip the wire to use the scotch locks.
I have seen prices range from $20 for the wire with no flags included to $50 for the kit here. If you need more than one roll it may pay off to price around by contacting different sellers. You can of course use any 20 gauge insulated solid copper wire. Just make sure it is burial rated if you are digging to install it because the labor is the most expensive part of putting in a system like this and you probably don't want to be replacing cheap wire that has failed any time soon. Also make sure it's UV resistant or else the sun will dry out and make the wire jacket brittle over time. I used a lawn edger to dig a trench 4" deep and used a wooden paint stir stick to gently push the wire into the trench. I used my shoe to fill in the trench and pack the earth back down. Good luck with yours! Take Care.
