Shop build. HEAT!

Ok so wiring questions. Also air compressor placement.

I plan on getting a compressor or rebuilding one I already have. Either one would be a big heavy beasty.

I have been looking at new compressors. Some say they require an 80 amp breaker. I would need huge wire to do that. The compressor will be on the opposite side of the shop. So 9 ft up to the ceiling and 40 ft across.

So if a compressor requires an 80 amp breaker I need like 2gauge NM-B stuff or 4 gauge THHN wire?

That just seems excessively huge.

Also I think to make some use of wasted space I'm gonna build a platform and mount the compressor on the platform.

Just been thinking about that today cause my head has decided today is a good day to think about stuff and try not to move much

Build a platform near the power source. Reclaim that floor space and also reduce your copper costs. Win-win. :)

Yah I know but I'm trying to be as efficient as possible with space and across the shop puts it above the man door. Which is fairly useless space. The breaker box will be on the side of the shop where trucks are gonna be.

Or it might not be. Gotta see how much feeder wire my cousin dug up and then I can just trench across to the other side.

I think you need #3 wire THHN for a 50' run and wanting 80amps.
 
If you mount an aircompressor to a wooden floor you're probably going to end up bouncing that floor and will turn that into 1 big resonator - like a giant subwoofer. Not good for noise or longevity. You'd have to brace the crap out of any wood floor you used.
 
Most 60-80 gal dual stage compressors pull 40-50a on start up. That be one hell of a compressor to pull over 60. One thing I ran into Eric, is that code requires anything below 8 feet to be protected. Meaning if the walls are unfinished, you need to sleeve the romex in conduit. If you plan on finishing the walls no issues. Depends on if you plan on having an inspector show up .
 
The walls will be covered.

Already got 64 sheets of 7/16 OSB.

I am not getting a compressor as of now. I looked at pretty much the biggest one I thought I might someday buy. I have an old compressor that I'm hoping to restore.

But in all reality the small shed outside of the shop makes absolutely the most sense. Reduces the wire run, gets it out of the way, forces me to build some sort of air distribution system.
 
Shed out side would be my final destination for one that is insulated so as to not freeze the blasted thing. If it is out side it doesn't waste any floor space.
80 amp is a ton a lot more then one would need that I would get.

Schedule 40 PVC pipe is what I have seen a lot of shops run the air distribution systems with.

Nope not ever. I still have a scar from a PVC air distribution system. Probably just do sch 40 black pipe.

And yah I will insulate the little shed

Won't help much unless it also has access to heat. Maybe omit the insulation from the shared wall so the shop will leak heat into the shed? Or you could just run an air vent to allow circulation.

Either way it kinda defeats the noise deadening aspect a little bit.

Will run a vent. It gets cold enough here I will more than likely do the intake in the shop too. But there are other ways to defeat noise even though the air circulation will come from the shop. Air moves around obstacles. Sound really dislikes obstacles
 
I bought a compressor last year 5hp 2stage and it keeps up w/ all of my demands, a true 5hp motor and it only required a 45amp circuit. 80 is a pretty healthy compressor! Gotta be up close to a 10hp.

Garage doors got delayed will be here next week. Probably gonna end up working on a couple of his trucks for a free install.

Electric is 3 weeks out ish.

Another guy is seeing how much it's gonna be for the tin for the front wall and a to wrap around the garage door framing.

Got my electric layout decided.

So moving along just nothing super noteworthy
