Electric ground for electric fence outlet question (lemm.ee)

Hello, I bought an electric fence kit for some goats and horses for a plot of land which requires grounded power outlet.

I wonder if a TT ground connection for the outlet (or fuse circuit the outlet belongs to) would suffice or if I need to redo the whole barns electrics since it's all ungrounded at the moment except for a 3 phase outlet connected to the garages electrics.

I just want to know what I should ask an electrician about when I ask for quote and time. If I need to redo the whole wiring I need to hold until next springto so I really hope for a smaller job :)

If I use wrong terminology Im sorry since English is not my first language

I think you should be able to split off from the 3 phase outlet. Maybe you will need a small breaker box. It depends on which breakers are connected to the 3 phase outlet.

Thanks, that will give me a place to start :)

What's a TT ground?

I know this is a bit late, but a ground is a ground. Assuming the current draw of the electric fence is under 20 amps, a 12awg (or metric equivalent) tied to the grounded 3 phase outlet's ground and run to your new plug for the fence should be plenty sufficient. Or, drive a ground rod next to your outlet and punch it on there.

TT means that there is a ground connected directly to the equipment housing, so basically a rod in the soul connected to the box.

I solved it with a connector from the 3 phase outlet so it's no stress to get an electrician out to sort out a more permanent solution.

Even if it's a late reply I appreciate you taking the time!

Ah gotcha, here we just call that an equipment ground, it bonds all the housing, motor casings, conduit, junctions, etc. All good!
