How many joules per mile of 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. Click to see full answer.
What is the joule of a fence?
The joule is a mathematical equation of Voltage x Amps x Time. The longer the" on-time" of the pulse, the higher the joule rating will be and the longer the "on-time" the less safe the fencer is to use and the less effective. how big of a fence charger do I need?
How many volts does a fence line need?

Output joules are approximately 70% of the stored joules. Even the voltage at various resistance levels across the terminal (try 25 ohm or less on the bigger units) can be misleading because that does not take into account the on time of the pulse.
Why is the conductor of a fence so small?
If there is very little load on the fence, the conductor (wire) can be very small like the stainless-steel wires in twine because very little amperage is needed.
