All I have, is a disconnected milling machine, as I have mentioned in my initial message and four wires; but yes in order to give you a better clue, I can send you tomorrow a picture with the name plate of the electric motor that runs the machine, just let me know.

Thanks for the picture. If you have a single-phase panel, the red and black wire Will Go On a double pole breaker the green wire will go to the Ground Bar and the white wire will go to the neutral bar. Please let me know if you have any further questions thank you
