## How many joules is a good electric fence?

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. Anything nearing 7,000 volts may cause induction.

## How many joules does a cattle electric 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 does joules mean on a fence charger?

Joules – A measure of energy that essentially tells you the relative power of each energizer. For comparison with other brands, we provide both the “stored” and “output” joules for each product. Remember that the best use of this number is to look at two chargers and determine which one is more powerful.

## What is the average electric fence voltage?

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.

## Is 1 joule a lot?

This is due to the fact that a joule is an extremely small amount of energy. To put how small a joule is into perspective, a liter of gasoline has 31,536,000 joules of energy in it. A kilowatt-hour is equal to 3,600,000 joules.

## How many joules is lethal?

An object which impacts a human is considered a 20% chance of being lethal with a head strike if its energy is greater than 80 Joules. It has a 90 percent chance of being lethal with a head strike.

## Can fence posts be 10 feet apart?

Typical spacing is right around 8 feet between each post however different circumstances may call for different measurements and it is not uncommon to have spacing between posts reach up to 10 feet. Once you have a rough idea of your post layout start by digging your first hole.

## Will a cattle electric fence hurt a dog?

Unlike the shock you feel when you touch a physical electric fence, the correction from a dog collar is generated by a battery. The wire in the ground sends a signal to the collar, but the electricity in the wire has nothing to do with the zap. But no matter how high you get, it can’t hurt your dog.

## How many joules is a fence charger?

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.

## How much power does a fence charger use?

The typical Zareba® fence charger uses about 33 watts per day. So, 33 watts multiplied by 31 days is 1,023. Divide that by 1,000 to get 1.023 kilowatt hours per month. The U.S. average cost of a kilowatt hour is 12 cents.

## What does joule output mean?

Output joules indicate the amount of energy sent through the fence. Stored joules are the amount of energy in an energizer’s capacitors – multiply stored joules by 0.7 to get an estimate of the output.

## Why is my electric fence losing voltage?

This can be caused by a broken underground cable, broken wire or insulator, a loose connection, or something touching the fence, such excessive vegetation. The Digital Voltmeter can help you locate the source of a short by measuring the voltage in the fence line.

## How many volts can a human sustain?

Liu survived more than 70,000 volts despite experts’ earlier warnings that the human body can tolerate a maximum of between 20,000 and 50,000 volts, which might prove to be lethal.
