Title: Electric fence power
Post by: chickenwing654 on March 29, 2018, 12:42:50 AM
Hi,

My electric fence energizer got fried during a  power surge late 2017.  Before replacing very soon,  what is recommended for a output.  I've been told Joule is a big factor rather than just volts.  This is to keep black bears out of my hives.  I got hit two summers  ago and decimated my three hives in Maine.

Been toying with solar energizers but they are not as powerful as plug in (I am close enough to power to run extension cord to shed),  Wondering what is suggested.

Thanks
Tazz

Tazz,
If you are dealing with bears, I would get the highest rated one I could afford. I have 110 units and solar powered units. For bears I would the 110 units. I can touch my solar unit briefly and not get zapped because it has a very brief shock every second or so. The good side of these units is that they give you time to get off of it if you do get zapped. I once tried to go through mine after I thought I turned it off. It dropped me to the ground and all I could think was roll out of it and I did. If it was a standard 110 unit, I don?t think I would be writing this.

I have a 12V unit, made in New Zealand, designed to feed 40 Km (25 miles) of line and burn-off grass touching it over that length.  When I used to keep sheep, I kept a 12V vehicle battery in the shed on permanent trickle charge, and ran the unit from that.  Dunno if it would discourage bears - I only ever touched the wire once - and once was quite enough for me.

Hi Taz
These guys invented the electric fence back in the 30's. They are the go to guys re electric fencing. I am sure they would be able to advise you on the best solution for your bees/bears.

I have a 110volt unit that charges a 50 mile fence.
The discharge rate for it is 2.0 Joules.
I accidentally walked into it and it put me on the ground.

Parmac Magnum 12 is the gold standard.  I used a Gallagher too.

I had a feeding station with honey behind it and my bears just lay on their elbows and looked in from a safe distance.
