Decide on the length of each run, as well as the height and the number of wires necessary to complete the job. Price the wires per foot at your retailer to get the best deal possible. Different chargers are optimized for different lengths of wire. Check with your supplier to make sure that the charger you intend to get will work with the planned length of wire for your enclosure.

Don’t buy chargers with foot or mile power ratings, instead select a charger that’s rated by joules. A higher rating in terms of joules doesn’t mean that the charge will be stronger if an animal gets jolted, it just means that the electrical current will be more consistent, making a high-joule charger the smartest purchase. If you’ve got a five acre fence, you’ll need at least a joule at the minimum.

Making sure that the fencing is easy to see is one of the most important considerations. 1. 5- or 2-inch poly tape, braid, rope are perfectly effective for most purposes. Coated wire is likewise easy to see and to install. Half inch tape is probably too small for a more substantial fence, especially for horses or keeping deer out.

To keep the charger protected, hang the charger on a post or wall of an outbuilding. Do not turn the charger on until you’ve installed the fence.

Don’t use too many posts. A common mistake is to install posts too frequently, thinking this will result in a stronger and more secure fence. However, if you do plan to install your posts 40 feet (12. 2 m) or more apart, you should install stays along the wires to keep them evenly spaced and create greater stability.

Most common are are insulators that allow braided or rope style fencing enough space to slide through, helping to avoid rubbing.

Never just wrap the wire around the fence posts, because the cable will come loose more easily and corrosion can occur. Use the connector clamps provided by the manufacturer. The wires will need to be pulled taut at the anchor end. There are a variety of methods for doing this: you could install a self-locking ratchet-style wire tensioner, use a come-along cable puller, or install a turnbuckle cable tensioner. Tighten the wire as much as possible, but take care not to place so much tension on it that it breaks, as this can result in serious injury.
