Any electricians?

I should be receiving a decent compressor in the next few weeks.
It requires 240v single phase. Where I want it only has a 120v line.
Any electricians here that can run a dedicated 240 line?
Not sure if I need to add a new breaker, but I'm willing to pay for the service.

A lot of those motors will run on 120 with a little tweak but amperage doubles and voltage drop increases.

Wire size likely won’t be big enough in the existing 120v outlet if you try to do that. Always run it at the higher voltage (240v) on a dedicated circuit if you have the option. Your lights will probably dim every time that thing kicks on at 120v.
 
There are a few electricians here. Make sure the one you get has some experience (or at least competence) with compressors. With a dedicated compressor circuit, breaker size can be very different than you would normally use for a specified wire size. Depending on the size of your compressor, probably 10 or 12 ga wire and a 30 or 40A breaker. If you are pulling an electrical permit for this, you may be forced to do afci breaker for a ton of money.
 
Agreed, why I want it done properly.
It's a home use compressor, but I'll recheck the spec and post them.
 
A 240v upright compressor, hard wired does not require an AFCI breaker. A new 120v 15a or 20a receptacle will if it’s in an attached garage, if it’s a detached garage AFCI breakers are not required as it is not considered part of a “dwelling”. Typically for a 60 gallon 240v single stage, single phase compressor I would run a 10/2 wire on a 30a 2 pole breaker. Two stage compressors may be a little different.

what is the amps?
 
I sold compressors for a few years , brother still sells them . Our service guys said the number one problem with cooked motors and service calls for “hard start” when under load was undersized wiring . If it’s not in the primary circuit ,buddy loads it on his wagon and takes it out to the end of an extension cord ( he made himself) out of sixteen two and two twenty plug from Home Depot .

It's an upright 80g in a separate building

I have to hydrotest the big tank I picked up before I put it into service. To get more air on my existing system I sometimes run multiple compressors in parallel for jobs I want to speed up. Hopefully when I get the new (to me, it's old) compressor running, that won't have to happen as often.

If you can post a pic of the label on the motor that would be ideal; or at least horsepower...

Is there a sub panel in the building, or will it have to go back to the main panel? Distance matters as well.

Depending on what panel it is, some breakers are harder to get than others... or at least costlier.

Could be relatively simple to an absolutely nightmare, unfortunately.
 
I’m sure you know this but majority of the cost is running the cable.

Get the electrician in, find out what’s what and then run the appropriate cable yourself.

Once that’s done get them to connect it all and enjoy all that compressed air!

I want a small dedicated compressor also…but that’s a job for another time.
 
Not really relevant, but kind of , one of my friends in manufacturing that used compressed air for ever running sanders and grinders and drills has slowly swung to DC powered sanders and grinders for better control and consistent torque . Expensive as heck upfront and you can’t drop them like a Chicago pneumatic sander . The world changes .

DC as in battery powered or some fancy industrial equipment that runs DC to the tools?
