Wires care only about amps. You can use 20 AWG wire for 220V. You can also use a 4/0 AWG wire for 220V. It all comes down to amps. Quick Example: For a 10 amp 220V circuit, you can use a 20 AWG copper wire (because it has 11A ampacity). For a 200 amp 220V circuit, you should use 3/0 AWG copper wire (because it has 200A ampacity).
