Questions:
1) What amperage should I make the breaker in the main panel that leads to the subpanel? Minimum 40A, but the standard would be 50A
2) What gauge wiring should I use from the breaker in the main panel to the subpanel?
6 gauge
3) What amperage should I make the main breaker in the subpanel? I assume it should be the same as #1. Yes, 40AMP minimum, but 50A would be more normal. They should match
4) What amperage should I make the breaker for the 240v air compressor circuit? 2.5* the rated amps, rounded to next highest. This will be 20 Amps
5) What gauge should I make the wiring from the breaker for the air compressor circuit to the socket for the air compressor? At 240VAC/20 Amps you will need to run 4 wires, For a motor, 10 gauge would be recommended
6) What type of socket (and pigtail) should I use for the air compressor? There are many. A NEMA L14-20P & L1420R will probably work well
