I'm moving in a couple weeks and although the new shop has it's own 200 amp service, there's not a 220V outlet in the place. I'm not getting a hoist right away, but I'm planning for the future and putting in all the outlets before I move any equipment in.

How many amps does your 2 post lift take? I will probably buy a 10K lift if that matters.

The last one I wired was 16 or 18, cant remember exactly.

I'm guessing 30 amps. You could always run wire rated for 30 amps and change out the circuit breaker at a later time. 10 gauges is rated for 30 amps at 230 volts.

IIRC most units up to 10k don't exceed 20A. Accordingly I think I only ran #12 for mine when I get one.

Run 10 gauge wire then install the right breakers depending on the machine. A 5hp motor requires about a 30 amp circuit and there is a real chance you'll need it. Bigger air compressors have motors like that. In my shop I have woodworking equipment that require 30 amp circuits and welders too. Finally, I was surprised that my makita 110 volt chopsaw kept blowing 20 amp circuits too. I was able to upgrade just the outlet and breaker to 30 amps and solve the problem.

Run 10 gauge wire, you'll be happy you did and it's not much more expensive at all.

Thanks for all the answers. 30A is the minimum I would put in for a 220V circuit. I just wanted to know if I needed anything bigger for a (future) lift since I'm adding circuits in the near future.

where are you guys putting the plugs or running the wires? Up to the rafters or along the ground to the wall

The last two I installed were 2hp units. They run off a 2P 20A breaker at 208V. The Code has formulas for the max size breaker/fuse and min. wire size you should use for a given motor's full-load current draw. Please don't just plug it into your 40, 50, 60A welding circuit. :shaking:

Wiring from overhead seems to work best from my experience - or if the ceiling is very high, jump off a side wall above head-height. (Keeps the floor clear from rolling equipment, and minimizes wiring damage.)

Also, try to find a "thermally protected" model - then you don't have to get separate overload protection.
