Circuit for this Sanborn compressor?

[Nick_Wa]

Just picked this up tonight. Sanborn Magna force 20 gallon twin cyl. compressor.

Wondering what type of circuit to run to supply. Probably will stick to 240 volt but not sure if I should just do 15 amp or 20 amp.

Its a 2 HP , 3450 rpm with the spec plate showing 115 volt/230 volt, 22 amp/11 amp.

Also what size wiring. Thanks.

I would do #12 AWG with a 20 amp 2 pole Bkr. 240 volt.

I would use # 12 and 20a, 240v

Great buy. I have the twin to it. It is a great little unit and very quiet for what you get. If you stay with the 220/240 go with the 30 amp service. When I first moved into this house I only had a 15 amp 220 available. It didn't provide enough amps to support the compressor when I was using air tools. The electrician said I could have damaged the compressor motor. I think the electrician used #10/3 on the sub panel and plug.

I have a sanborn with a 3hp motor. I ran it with 12ga wire and 20a breaker and have never had an issue.

Your lucky!

So is there any issue with running 30A / 240V outlet with 10/2 even if it is a bit oversized? Assuming material cost is roughly the same...

Or is there really no need and I should just stick to 12/2 on a 20A / 240V outlet?

Edit: Faceplate says "Peak Amps: 26/13A" So 13A peak on 240V I suppose there shouldn't be 20A draw even on starting?

Ok, so I went to the store yesterday and decided to go a little overkill for now so that I can change the breaker in the future and use it as a welder outlet as well. I don't see any harm doing it the following way as I will be keeping with a 20A breaker for the compressor.

#6 wire (have some leftover)
Double pole 20 amp breaker
50A 250V Plug
50A 250V Receptacle

Here are the receptacle and plug:

Any objections or reasons not to do this?

Thanks!

My friend just grabbed this 20 gal for $40 off craigs, sure seems like a good little unit, its wired 110v.

Fwiw- My 5hp peak 30 Gallon Eagle V twin belt compressor is on 24/7 with 110v/20amp (plug). Has been since new in 2010, no issues. I run Grinders/Impacts/Ratchets/Cutting wheels on it so I use it. Starts/runs just fine, builds fast, Eagles are great compressors too.

FYI, it's not a 5hp motor, regardless of what the label says.

Peak not running hp. A 5hp Eagle won't run on long ext cords like 2 or 3hp rated units will. So its more hp than most have.
Most portable units don't have over 110v because buildings rarely ever have more than 110 outside which leaves one rather useless as a porty unit. A bigger motor limits its usage considerably.

If I were installing it for a customer, I would use a 20 amp 2 pole breaker, #12 wire and a 20 amp 250 volt receptacle and plug.

There's nothing wrong with 30 amp but it's overkill.
