I made a power cable with a plug on one end that plugs into a 220 volt dryer outlet. What are the three wires, at the other end of the cable, connected to in my 3 phase, wye wound, 9 lead motor. It has wires 1 & 7 connected to wire L1, 2 & 8 connected to L2, 3 & 9 connected to L3 and 4,5,6 wired together. Thanks, henrylr
