Electric fence advice

.15 joule doesn't seem like much . But if it works...... I guess mine is over kill @ 32 jouels

I totally agree and was concerned that it was so low. I don't know why it works to get me 9200 volts at the far end. I thought I would need at least 2 joules - and I read that a joule a mile is recommended. The units I checked out at TSC were mostly under a joule, one at 2.2, and another at 4 I think but it was over a thousand dollars. 32 joules would likely work at San Quentin.

The number of joules needed has a lot to do with the lack of resistance of the wire or tape. Heavier wire will work better, copper wire works a lot better, and stainless is ok. We use a braid of polyethylene, stainless and tinned copper. Copper is nearly a thousand times more conductive than steel.

All the best,

I don't know how a .15 would shock but I can tell you that 32 feels like you stuck your hand into 240 volts !

I was bent over close to the wire never thinking about it. I accidently raised up, touched the wire with my head, and it felt like someone hit me across the back of my neck with a ball bat ! And that was with rubber sole boots on.

I've seen my 2300 # bull touch, it and heard him scream ! Never heard a scream like that. He is grounded with four feet on the ground though .

They may not make a solar charger that large though
