Anybody know how to change a 110v regulator to 220v

bought a new 220 air compressor, less tank and regulator.

have an old 110 unit that lost the pump hard. (it was an integral piece of crap) nice tank, though.

I'm pretty sure I can just rewire the box where the power disconnects, and wire it to go 22o...

any electricians here?

@Rockhead,
If the regulator is just a simple pressure switch when it should have no problem switching 220 instead of 110 however if it contain any other elements I would not try it.

@Rockhead,
If your new motor is single phase, I think you will be good.

@roger,
it is...

basically the regulator just acts as a switch to shut down the power at x pressure.

need to know what goes where to make 22o...

my electrician buddy was at the bar all night.

gonna try and catch him early tomorrow.

i've got to make a 15 foot cord, anyhow...

@Rockhead,
I'd tell you how, but if you electrocuted yourself then I might feel responsible.

220v - 2 hot lines - hook up a 2 pole breaker and run one line from each pole - will give you 220v. (Can't be 3 phase or you will get 208v.)

110v 1 hot line - 1 line goes to breaker, other line goes to neutral bus. (Now Chumley is going to yell at me because I used the term neutral.)

@Rockhead,
I once converted to 220 by accident. Popped a couple of bulbs in the process. I don't remember the process, but it can't be too hard if it can be done unintentionally, right? Somehow, it involved misconnecting the ground wire.

@roger,
i'm real good at oooops, that was wrong.

i was hoping to avoid that method here... (22o gets my attention)

I'm done structurally now, and have to get some copper tubing in the morning (around noon prolly)

mebbe an answer guy will pop up.

or my hardware store guy is pretty sharp, too...

@Rockhead,
Working for beer isn't the problem.

Expecting someone who's been at the bar all night to be up early... that's the problem.

@DrewDad,
you gotta understand country folk, dad...

anyways, I got it figgered out, i think.

its all hots. the grounds hit the case, and the terminals are hot hot on both sides.

until they're not. Shocked

he's gonna come double check me for a beer on his way to the bar before I plug it in...

@Rockhead,
As long as you can read 22ov across the 2 hots, you should be OK.

@parados,
ok.

it worked, but not without some drama.

a dumbass was to blame.

initially i suspected myself, as usually this is a good startng point.

after triple checking myself, i went for the electrician.

the motor would start and run, but kinda like gram runs. it didn't look comfortable at all, and was totally not really running...

the dumbass that had wired the shop had his wires crossed at the outlet.

hums right along now.

I owe him a 12 pack of crappy lite beer...


thanks to all who helped out.
