# What should I look for in an electric fence?

Contents

To place an electric fence, you always need an energizer, a power conductor (ribbon, wire, etc.), fence posts, electric fence insulators and earthing equipment. What types of products you use for this depends on the type of animal, the size of the area and whether it concerns permanent fencing or a mobile variant.

## How many joules is a good electric fence?

Ratings range from 1 to 20 joules. Experience at the University of Missouri Forage Research Center has shown that allowing one mile of fence per joule output is satisfactory in most situations. To control most livestock, maintain fence line voltage of at least 3,000 volts.

## What should I look for in an electric fence energiser?

Key points:

• The most economical power source (hydro, batteries, or solar) depends on ease of access to fencer.
• Output voltage needs to be high enough to get the attention of the livestock being contained.
• Output joules rating must be capable of delivering the voltage along the length of wire in the fence.

## How strong should an electric fence be?

That said, most sources recommend a minimum of 4,000 volts for hard-to-control species, and a minimum of 2,000 volts for more docile animals. Anything greater than 8,000 volts is considered more than necessary (some sources say 6,000), and more likely to cause injury.

## What is the average voltage of an electric fence?

An electric fence will have a voltage range that can vary from 2,000 to 10,000 volts with 10,000 being the maximum permitted by international regulations. The amount of voltage chosen will depend on the distance that the fence can be shocked up to with the desired power of the shock.

## How big of a fence charger do I need?

Number of fence wire strands.

As a general rule for multi-wire fences, divide the charger’s distance rating by the number of strands, then select a charger with a mileage rating that meets those needs. Always increase power needs when adding additional wires.

## Are more joules better for electric fence?

A fence charger has to have enough joules to push the voltage down the fence line and through a load. … Typical recommendation is one joule per mile of fence. Keep in mind that bigger is better, until the point that induction occurs. Induction will power gates and neutral wire when voltage gets too high.

## How many volts are in a Joule?

Table of Joules to Volts for conversion, equivalence, transformation (Coulomb: 10):

How many Joules are: Equivalence in Volts:
1 Joule Equivalent to 0.1 Volts
2 Joule 0.2 Volts
3 Joule 0.3 Volts
4 Joule 0.4 Volts

## How many joules does a cattle fence need?

Gerrish recommends 1 joule of output per mile of fence, regardless of how many strands of wire. If there’s a total of six miles of fence, it requires a minimum of a 6-joule energizer.

## What is the most powerful electric fence charger?

The M10000i packs 100 joules of stored energy and will outperform any other electric fence energizer on the market powering 125 miles / 3,000 acres of multi-wire fencing.

## What does joules mean in fence chargers?

Joules are the most common means of comparing fence energizers. One joule is equal to an electrical. output of 1 watt per second. Comparison by joule output is only valid if the pulse lengths are similar. and if measured at comparable resistance levels.

## How good are solar electric fences?

Not only are they considered safe and effective, they’re among the least expensive fencing options. … You can potentially save even more money by investing in a solar fence charger. Getting a solar-powered unit allows you to go off the grid and harness the energy of the sun to power your fence.

## Why is my electric fence clicking?

Clicking is part of normal fence operation when a charger releases energy that travels along the fence. … Almost all radio noise generated by electric fences is caused by a spark or arcing of the electrical current across fence hardware.

## How many volts does a pig fence need?

To safely contain pigs, you need a Zareba® fence charger that maintains a minimum of 2,000 volts on the fence line. Voltage levels are impacted by vegetation on the fence line, length of fence, and type of wire.

## How bad is the shock from an electric fence?

The shock from an electric fence is more of a memorable discomfort than harmful pain. … Fence energizers produce low-amperage, high-voltage shocks, which are not harmful. Outlets produce high-amperage, low-voltage shocks, which can be dangerous to animals and people.
