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.
How many joules should an electric fence have?
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.
Will 12 joules electric fence hurt 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 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.
How many joules do I need for an electric fence for bears?
Bears are more likely to pay attention to an electrified fence that delivers a painful shock. For deterring bears in developed areas, your energizer will require a minimum joule rating of: 0.7-1.0 stored joules or 0.5-0.7 output joules.
How many joules does a pig fence need?
Pig Electric Fencing Charges and Voltages A 6 joule charge is ideal. This will keep in the most determined of escapee pigs. You might need multiple energizers if you are planning to cover a large amount of ground. If you fencing a large amount of land (20 acre or more) use a 15 joule energizer for every 20-30 acres.
How many ground rods are in a joule?
A general rule is to install a minimum of 3 feet of ground rod per joule of output capacity. A 15 joule fence charger will require a minimum of 45 feet of ground rod. These rods must be installed at least 10 feet apart from each other.
Can a dog jump over an electric fence?
Your dog cannot tunnel under or jump over the invisible fence. That’s why invisible dog fences can be useful.

Can you have too many joules?
Clamping voltage is the amount of voltage it takes to gets the surge protection to kick in. The lower the voltage, the better the protection. It doesn’t matter how many joules your surge protector has. You shouldn’t buy anything with a higher voltage than this.
How many joules can a human withstand?
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.
How many joules is in a Volt?

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.
Is .10 joules enough for pigs?
For hogs, a minimum of 10 joules will keep your hogs where they need to be. Before I did this, my fence chargers were purchased with the miles of fence in mind, have two chargers that state they are good for 50 miles.

Why do you need 3 ground rods for electric fence?
In fact, the majority of electrical fence systems will actually require at least three grounding rods. Grounding rods can actually interfere with phone service as well as electrical lines that may be located on the property. For this reason, it’s important to place grounding rods as far away as possible from utilities.
