How many joules do you need on an electric fence?

75 joules and usually less. Therefore, they are only designed to power a maximum of a few miles of wire. Generally, you will need about 10 watts of solar panel for each output joule of the energizer. Example: a 6 joule charger will need a minimum of a 60 watt solar panel.

Similarly, it is asked, 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.

One may also ask, how much electricity does a electric fence 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.

Thereof, how many joules do you need for horses?

One joule is a minimum rating for fencing that encloses up to five acres, but I always recommend getting the most powerful charger you can afford. A higher joule rating doesn’t mean the fence’s jolt–which can’t injure horses or other animals–will be harder or more painful, but that it will be more consistent.

How many joules is dangerous?

Greater than 10 Joules is considered hazardous. Greater than 50 Joules is a lethal level.
