The size wire you need to operate with a 40-amp breaker safely is an 8-AWG wire. It is possible to install a 40-amp circuit breaker on a larger gauge wire such as a 6-AWG wire, but installing it on a smaller gauge wire will violate the code.
What wire do I use for 220V?
A 30 Amp circuit is needed for most 220V tools. You will need to run a 10-2 to the outlet. 10-2 copper wire is usually good for up to 40 Amps on start loads and 35 Amps on constant load.
