Most Common Fence Questions

Kencove-sign_blogHere at Kencove, our product specialists answer a lot of questions each and every day. And when they say you learn something new each day, believe me it’s true! In fact, I think it’s safe to say I learn something new about fencing, energizers, insulators, or posts each and every day I am here. The top three most popular questions that we are asked are about post spacing, the correct size of energizer, and the life span of our posts. You asked, so here are the answers.

How Far Apart Do My Posts Need To Be?

Although every situation is slightly different, there are some guidelines to keep in mind when helping customers select the proper amount, size, and type of post to install on their property. Typically on flat, even terrain, we recommend spacing wood posts at 20’ apart for cattle or 12’ spacing for horses. You may opt to add fiberglass rods or t-posts in between to allow 50’-100’ spacing between wooden  posts. You would drive fiberglass rods or t-posts every 25’ for cattle. We recommend spacing your posts 12’ apart for horses due to their poor eyesight. By keeping your posts aposts-blogt 12’ intervals, you are adding to the visual barrier of your fence and safely containing your equine friends.  If your terrain is slightly to moderately rough, we recommend spacing your posts a little closer together at 15’ for cattle and 8’ for horses. If your pasture isn’t very square or runs through a wooded area, we recommend 8’ spacing for your posts with braces at every turn. When working with polywire, polyrope, or polytape, you can use fiberglass rods or t-posts every 12’ with bracing using wooden posts. We would also recommend having wood posts installed every 100’ to support the polywire, polytape, or polyrope. When working with PasturePro Posts, we recommend a spacing of 20’-25’ depending on your terrain and type of animal you are containing. You will still need to use wood posts for bracing.

Will My Energizer Be Powerful Enough?

ek9hThere are a million and one different sayings associated with energizers and the length of the fence they will effectively energize. The most accurate, however, is a minimum of  one joule per one linear mile of multi-strand perimeter fence. As with every other product and situation, this is just a general rule of thumb. For high-tensile fence, we recommend one joule per one mile regardless of the number of hot strands on your fence (please refer to the diagram for proper installation of wire to achieve the one joule per one mile ratio). eks-5hIf at any time you are wondering if an energizer is too large, remember it’s better to go big or go home in this case. Some of our larger energizers come with a half-power option, which allows for expansion on your fence line without purchasing a larger energizer. Polytape, polyrope, and polywire are all more resistant than high-tensile and will require slightly more energy per mile to energize the fence efficiently. When working with our electric netting, it is recommended to use 0.25 joules-per-net, meaning you can hook up four nets with a one-joule energizer. You can use a larger energizer without harming the net, however, having too large an energizer, for instance, two joules on one net (8x the joules), could be fatal to small animals or poultry. We always recommend using a low-impedance energizer. The days of the “weed burner” energizers are done and over with. Low-impedance energizers last longer, are safer for you, your animals, and your property, and put less stress on your fence. If you have a high-impedance energizer you CANNOT use it on electric netting, polytape, or polywire!

A.) Each wire is added individually into the energizer sucking out more power, meaning each line receives less energy. B) One wire is ran out of the energizer, each wire is connected together at your starting point allowing for optimum power on the lines

Not all questions are equal, but here are a few questions that our product specialists still vividly remember.


Carla: “How can I fence out snakes?” Yes, you can successfully fence out snakes!





Bonita: “Where are the cookies?” In case you didn’t know, Bonita has world-famous cookies that make an appearance at all the shows she attends.


Lacy: “Can I put electric fence all the way around and over top my orchard trees to keep out squirrels?” This would be very expensive and difficult to create without grounding issues!


John: “How can we electrify our fence to keep the bears in and zoo visitors safe?” A California zoo purchased an energizer and fence supplies.zoo-bear





Ric: “A few years ago, I got a phone call from a golf course manager in New Jersey. He wanted to use goats to help clear up brush around an undeveloped golf course. I sold him electric nets, energizers, and all the other fencing necessities. When I called to check back in, he said the nets worked great and they were able to move the goats around the course to help clean it up and get it ready for development.”
