Compressor Wiring
 
2 Attachment(s)

Greetings electrical gurus. I'm attempting to install my brand new Ingersoll Rand 220v compressor. The installation instructions are useless. They just point to the connection and say "to power supply" and of course tell you to hire a qualified electrician. I have a lot of DiY experience with 120v circuits but not 240v.

So here's what I got. The first picture is my nearby 220v wall outlet. The Black-Red wires have 240v, and the Black-White & Red-White have 120v. The 2nd picture show my compressors electrical box. It has a black, a white, and a ground. So I was going to buy a 220v extension cord but not sure how I wire it up.

Thanks

Just to make sure I'm doing this right I attached the motor plate for my compressor.

The existing feed wire (photo #1 of my 1st post) is 6 ga. with a 50 amp breaker. The wire I plan to attach to the compressor is 10 ga., which seems about the same size as the factory wires that are there (photo #2 of my 1st post). I then plan to swap my 50 amp fuse for a 30 amp because a 50 amp breaker for 10 ga. wire seems rather large.

Does this sound like a reasonable plan?

Thanks again.
