I assume your sizing the 20 amp from the breaker? NEC 240.3 states minimum conductor size for the rated ampacity of the circuit breaker. In this case, minimum size for 20 amp breaker is 12 AWG. I assume you are wiring a motor? I suggest you size your over current in accordance with NEC, start reading around NEC 430.


When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?

When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
