★ ★ ★ ★ ★ (47) Read reviews »

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.

Common Uses

A 110V electric fence energizer used for medium length fences. It will keep in cattle, sheep, goats, horses, poultry and guard dogs. Effective at protecting against coyotes, stray dogs, bear and fox. It also works to keep deer, raccoons and rabbits out of garden/orchard areas.


Specs

  Energizer Only Plug-in Kit*
Item # 115110 115111
Kube 4000 Energizer ✔ ✔
(1) Ground Rod (galvanized) 6 ft
(1) Ground Rod Clamp ✔
MaxiShock Insulated Cable 100' roll
Digital Tester ✔
*Kits include all the parts and pieces that folks new to electric fence normally need to make the fence operational.

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. Low-impedance circuitry produces a short, very strong electrical pulse designed to cope with moderate weed load.

Miscellaneous

  • Requires a grounding system. Inadequate grounding is the most common failure in an electric fence system. We recommend 6 ft. of grounding for this energizer, included in the kit.

Energizer Specifications

  • 2.30 released joules
  • 2.30 joules in moist soils
  • 1.24 joules in dry soils
  • Pulses per minute: 40
  • 110V draw is 4.5 watt per hour
  • Impedance type: wide – pulse type
  • Input: AC only
  • 6' cord
  • Modular. Very easy to repair.


Benefits

Wide-impedance units perform better over a wider range of fence conditions and conductors than standard low-impedance units. Areas where wide-impedance units excel are: high resistance conductors (stainless steel polywire/hot tape/electrified netting); minimal ground rods; livestock or wildlife with dry skin or hair (poultry, deer, goats); and very dry soils. Safe to use with all polywire, polyrope, tape and electrified netting.


Installation

The Kube 4000 can be mounted either inside or outside of a building, but not where there is risk of fire. The energizer must be mounted vertically. Protect the energizer from direct rainfall.

  1. Connect insulated cable (stripped back 1 - 2" on ends) to the fence terminal on energizer, run the cable to the fence line and connect.
  2. Then run a second length of cable from the ground terminal (with ends stripped again) on the energizer to the ground rod.
  3. Secure to ground rod with a clamp.
  4. 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.
  5. 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.


Precautions

Make sure the power is turned off before working on the fence or the energizer.

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.


Troubleshooting

You’ll need an electric fence tester (included with kit) to measure voltage.

Start by measuring the voltage at the end of the fence line. If the voltage is below 3000V, follow these steps to determine if the problem is with the fence, or the energizer.

Test the energizer first!

  1. Turn off the energizer.
  2. Disconnect the wires going to the fence and ground stake/rod.
  3. Turn the energizer back on.
  4. Measure the voltage on the energizer between the two terminals (positive and negative) with a digital voltmeter or other high-voltage tester. Touch one end to “-“ (earth terminal) and the other end to “+” (fence terminal). The reading tells you how well the energizer is working without any other variables.
  5. If the tester reads below 5000V, then the energizer (or possibly the battery) is the problem. If the voltage is above 5000V, then the trouble lies with your fence.

If the energizer is at fault:

Determine if the battery or the energizer is the problem.
  • Test the battery with a low-voltage tester; recharge if lower than 12.2 volts
  • Check the grounding system
LEARN MORE

If the fence is at fault:

Re-attach the fence and ground wires to the energizer and turn it on. Then, walk or drive along the fence looking for situations that are reducing the voltage:
  • Conductors touching another wire, steel post or the soil
  • Broken or damaged insulators

Tara F from New York

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.

Excellent energizer with no fancy bells and whistles but it will sure pop your tale. This energizer packs a punch and really works. We use it to keep our sheep and a ornery bull in their appropriate areas. We have had no issues at all, and we will probably be purchasing another in the near future.

Had a neighborhood bear attempt to get into my chicken yard last night. He go popped and headed for the hills. Perfect. I wish I could upload the photo of what he did to the containment fence inside of the electric fence perimeter.

About Conductivity

Conductivity measures the amount of electrical current a material can carry. The opposite measure is known as resistance.

Tinned Copper Superconductor

Many of Premier’s electric net fences feature a green and white superconductor that has both stainless steel and tinned copper filaments for optimal conductivity.

These “premium” nets are 10 times more conductive (38 ohms per 1000') than “basic” nets offered by our competitors. This enables the electric pulse to travel much farther and be less affected by weed contact.

Customers who are unhappy with netting are often those who’ve chosen nets from China or their farmstore equivalents.

Types of Line Posts

Line posts are built into the net. Three options are available.*

Line Posts Compared
  1. Single Spike (SS)
    The best choice, unless your soils are always soft or very hard.
  2. Double Spike (DS)
    Posts allow you to push in the spikes with your foot. When soil is hard or rocky, double spikes are more difficult to install and remove.
  3. Drivable Posts (DP)
    Allows use of a mallet or dead blow hammer for installing posts in dry, hard or rocky soil. Features a “spike stop” for extra support and internal fiberglass ribs for added strength.

Tip: To insert a line post into frozen or hard soil, use a power tool to drill pilot holes.

* Not all fences have all line post options.

About Positive/Negative (Pos/Neg) Nets

Is your area dry?

Conventional electrified fence systems rely on soil moisture to be effective. However, not all areas have the required moisture.

Dry soil increases resistance—a weaker, less effective pulse occurs that does not deter animals.

To overcome this, Pos/Neg nets* are wired to allow the use of every other horizontal strand as an extension of the ground terminal. Because half the strands are connected to the ground terminal or ground rod, reliance on soil moisture is reduced. A PowerLink must be purchased separately to make the secondary ground connection.

How it works…

In order to receive a shock, the animal must touch both a positive (hot) and negative (grounded) strand at the same time. This will deliver more pain to the animal than an all hot net (Pos/Pos) because moisture in the soil is not required to complete the circuit.

Pos/Neg fences can be converted to Pos/Pos in moist conditions. Remember, all fences must be kept free of vegetation.

* Not all fences have Pos/Neg options.

Line Post Spacing

“Plus” nets—6'8" spacings between built-in line posts*

Line Post Spacing

Standard nets—10' or 12' spacings between built-in line posts*

* Spacings are approximate.
Distance between built-in line posts may vary by product.

Essential Energizer Advice

  • Buy a larger energizer than necessary. When the fence pleases, most folks will buy more fence—and need additional output.
  • Use a low-impedance intermittent pulse energizer.
  • Use a fence tester to check the voltage often.
  • Use enough ground rod(s)—included with our energizer kits.
  • Don’t allow your lead acid battery to discharge below 40%.
  • Use insulated wire that is designed for electric fences.
  • Always connect the fence to an energizer, not an outlet.
  • Visit this link for answers to other common energizer questions.

Two Basic Types

  1. All-in-one Solar
    • Solar units are very portable.
    • Because they need a battery, these units are more costly to purchase and operate than plug-in units.
    • Batteries are less effective in cold temperatures (deplete faster).
    • Most farmstore solar units are too weak, in joules of output, to properly energize netting. That’s why we designed our own.
  2. Plug-in & Battery
    • Least cost to purchase and operate per joule of output.
    • Best for fences exposed to heavy vegetation.
    • Cold temperatures do not affect performance.
    • Recommended for whole-farm systems, but can be complex to install. Higher output requires more ground rods, underground cables, multiple output terminals, etc.

Braided vs. Twisted

Braiding instead of twisting the horizontals increases the frequency of metal filaments on the outside of the strand.

Braided vs. Twisted Electric Net Fences

What’s the benefit?

  1. More metal is exposed on the outside of the strand. This enables improved animal to conductor contact. The electric pulse is better able to travel from the fence and into the animal, resulting in a memorable shock.
  2. A tighter, braided weave results in fewer snags when carried or pulled through pastures, reducing frustration.
