It sounds a little strange if these wires are where the power is to be
connected and goes to the switch. Is it possible that you have a 3 phase
motor?
You should see a 3 and a zero with a shash bar through it on the info
plate if it is. There may just be a line saying phase and a 3
stamped in it. These are standard colors for a 3 phase circuit and the
green would be ground. How big of a motor (HP) is it.
