Kube 4000 Energizer
The Kube 4000 plug-in unit is economic and wide-impedance. That means it produces unusually high pulse outputs in fences over dry soils. It performs better than standard low-impedance units during dry/snowy seasons and on fences for deer, poultry and goats.
It's proven, over the past 5 years, to offer reliability and excellent value.
To help simplify your purchasing decision, look to a Kube 400 Plug-in Kit.
- 3 stored joules
- 2.3 released joules
- 1.9 output joules in moist soils
- 1.24 output joules in dry soils
- Requires 6 ft. of ground rod in the ground
- 4.5 watts drawn per hour
- 48 pulses per minute
- 6' cord
- 2 prong plug
- Simple. No fancy "bells and whistles."
- Modular. Very easy to repair.
Should power... *
- 3 miles of 3 strand cattle fence.
- 1 mile of 5-7 strand sheep fence.
- 15 rolls of 164' sheep/goat nets and 7 rolls of 164' PoultryNet.
* All distances are dependent on amount of grass/weed load on the fence.
- Connect insulated cable (stripped back 1 - 2" on ends) to the fence terminal on energizer, run the cable to the fence line and connect.
- Then run a second length of cable from the ground terminal (with ends stripped again) on the energizer to the ground rod.
- Secure to ground rod with a clamp.
- Plug the energizer directly into an outlet and test fence. Do not use an extension cord as it may cause a decrease in voltage and expose the unit to the elements.
- Unit indicator light should flash and a tic-tac sound will be heard. If the indicator light doesn't flash, then the unit should be serviced.
To Reduce Risk & Liability
- Never place your head or upper spine near an electrified wire. Accidental head or neck contact can occur when pushing a voltage probe into the soil. Be careful when doing so to avoid head-to-wire contact!
- Never attempt to step over or climb through an energized fence of any kind.
- Never encourage anyone to touch an electric fence.
- To check—first turn off the energizer.
- Then disconnect the wires going to the fence and ground rod system.
- Turn the energizer back on.
- Then measure the voltage on the energizer between the 2 terminals (fence and earth) with a digital fence voltmeter or other fence testing device. Touch one end to “–” earth terminal and the other end to “+” fence terminal.
- If the tester reads under 4000v, the energizer (or possibly the battery if it’s a battery/solar energizer) is the problem.
- If the tester reads more than 4000 volts, the energizer is working properly and the fence is the problem.
- Check that the 110v outlet is "live" by using a plug-in drill or test light.
- If the test light works and the energizer does not, call Premier.
- Walk or drive along the fence looking for any point in which the energized wires touch the soil, a steel post or a steel wire. On HT wire fences, check the wires at braces to see if they are touching a hot wire. On netting, look for a hot wire touching the metal stake at the bottom of the plastic posts. Also look for damaged insulators.
- If the fence can be separated into several parts (by switches or by disconnecting parts of it), you can locate the problem by beginning at the far end and then progressively turn off or disconnect the sections of fence. When the voltage on the remaining fence rises sharply, you've located the section(s) that's causing the problems.
- The alternative to (2.) is to begin at the fencer and progressively turn on sections of the fence. When the voltage suddenly drops you can assume that the problem is in the section most recently connected.
Most energizers put out between 5000v and 8000v when there is no load (i.e. no fence hooked up).
If the energizer is faulty and it is a 110 volt plug-in unit…
If the fence is at fault, then you must find the fault(s) and fix them.
If you have a fault finder you can simply touch the fence with the fault finder at various points along the electric fence(s). The fault finder will tell you at each point which direction to go in to locate the problem. Move in that direction testing as you go and you will arrive at the problem.
If you lack a fault finder…

The Kube 4000 worked just fine last summer. This spring, on setup, it was not functioning. After several very helpful phone conversations with people at Premier 1, the decision was to purchase a new unit and ship the faulty one to Premier 1 for evaluation as to repair or replacement. After only a few days Premier 1 notified me of a refund of the price of the new unit, which is performing very well at this time. I want to compliment not only this product but especially the exemplary assistance and service from the staff of Premier 1.

We're small hobby farmers in Florida and have been using Kubes for about three years and have 4 currently. They’ve continued working perfectly despite being outside in the elements, including being halfway submerged for hours after our frequent thunderstorms.
We’ve never had any losses to predators while using a Kube - and once it killed an armadillo that got tangled in the netting!

I was using a low impedance fencer on my electric fence for my horses. It worked fine this summer but once we got snow and a great deal of ice this winter , it was sending a very weak pulse that had no shock value. We have sandy soil also. In researching the problem, I came across information that convinced me I needed a wide impedance energizer. The only one I could find was the Kube 4000 Energizer online. It had good reviews so I decided to give it a try. I am now receiving a 5500 v plus pulse through my fence. I am well satisfied with this energizer.

An excellent product. We’ve used one for ten years without a single problem and bought another for a new pasture across the road. Wouldn’t hesitate to buy a 3rd.

A great little energizer. It does a much better job of generating a charge to the fence no matter the ground moisture conditions. We use this on portable fencing to rotationally graze a small herd of sheep and it works wonderfully.
