You need to know the amperage to size the wire. For 220 V at 20 A you would need 12 AWG. At 220 V at 30 A 10 AWG.
A #8 AWG copper conductor with an insulation factor of 90 degrees C will limit the voltage drop to 2.26% or less when supplying 30 amps for 120 feet on a 220 volt system.
A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire on a 40 amp breaker.
Three phases, one neutral and a GROUND
Depending on the configuration of the cord cap, the green wire is ground, the white wire is the neutral and red and black wires are the 220 volt source.
