Wire size question for 220V run to garage

[jimmyfloyd]

Ok, I have an attached garage that i would like to run 220V power to for a pool Pump and air compressor.

First, what I have:

- I have 220V breaker space in the panel that was for a window AC unit that I will be repurposing. It's 20amp I believe.
- I have a 3/4 hp hayward Superpump in the garage currently running on 110V that I plan to switch to 220V
- I have a 20 gal craftsman oiled air compressor with a 20amp plug on it.


I would like to:

- Run a new power wire to the garage to power the pool and Air Compressor. - Ideally, I would have 2 outlets, one for each, and maybe a power switch for each.
- Alternately, I would have one plug, and would switch between them as needed, since I don't use the compressor often, and the pool pump is only on 4 months out of the year.


I have:
- 10-3 Romex I got on sale. I see this is good for 30 amps on 220V.
- 20 amp breaker, but can get a larger one.
- 40-60 feet between the main panel and the pump (farthest item) accounting for wire path.


Can I have 2 receptacles, or will I need to get a small box to put 2 breakers in, 1 for each?
Will 30 amps be enough for this?
Can I run the Romex in conduit once in the garage for protection?

I am not sure exactly where you are but it could be several thousand miles to the nearest 220.

Some countries in South America still use 220 volts. Sorry just had to laugh, but to to OP the current standard is 120/240 volts.

(i) You need to find out what the current draw is for each one of those two devices. Based upon that, you will know if a single 20 or 30 AMP breaker can service the two receptacles.
(ii) See above
(iii) NEC requires that the cable should be in conduit to be protected from physical damage

I would put in a small subpanel.

What is the HP rating for each motor?

Yet everyone knows what the OP is referring to....
