compressor wiring part Two

[rpsurfr]

A few days ago I posted asking for help with my new compressor. Pics were not included so here are a few.
To recap- I sold my old unit which was on a 20amp breaker with a on off switch -magnetic maybe? I did not post a photo of it drat
Ok here is the new unit

Quincy
plate reads
230 volts
21 AMPS this makes me wonder - but smoke in the wires is not my thing...
3450 RPM
60 HZ
Phase 1
the motor is a Baldor brand

The photos are of the two boxes that came with it. This is what confused me
The prior owner had 2 instead of my one and I think a 30 AMP breaker. My fear is my line will not support a 30 amp breaker although I have two 220 lines on opposite sided of the shop

I have alum wire going into the shop but the main is back at the house 60 ft away. I have another going in with a box on the other end as I added on to the shop.

Any thoughts would be great so thanks

rp,

It's a std 220 setup. You need a double 30 amp breaker at a minimum with wiring sized for the distance from the box to the compressor. That can range from 10 GA to 8 GA. It looks like the prior owner wired a off/on switch as well as the pressure switch with the mag starter.

You need to let the electrical guys on this site know what size wire you have running from the house to the shop, the breaker size at the house and where this wire ends up in the shop (sub-panel, on/off switch). Looks like a nice compressor...
