So I finally got a buddy over with a big pickup and bought a new 60 gallon compressor at Lowe's the other day. Putting the plumbing was a non-event, but the electrical is stumping me...

My wall outlet is a 14-30R, which is a 4 prong plug with green, white, red, and black wires as seen on the 30A wall plug I bought for the compressor.

But the compressor only has two posts to connect, white and black - green is a no brainer chassis ground. Question is where do I put the red wire, which is apparently a "hot" wire and is carrying 120v like the black? Intuition tells me to stack the red and black on the black colored terminal, but I'm not one to guess and kill new equipment.

Any experts out there care to lend me some advice?
