In above contactor wiring diagram i shown 3 phase 440 volts 4 wire system. I take one phase and neutral wire for MC coil which 220V, but always wire your contactor coil regarding coil voltage /. For 120/240 Volt 3-wire: Connect X2 and X3 together and bond to equipment ground and building ground. 240V outputs are X1 and X4, neutral is the X2/X3 connection For 120 Volt 2-wire: Connect X2 and X4 together and bond to equipment ground and building ground.. This wiring should not be used on 240 volt circuits. 240 volt, 1 phase motors should use a 2 pole starter. L1 is Line 1 in and should be connected to one of the "hot" wires, L2 is Line 2 in and should be connected to the other "hot" wire..
