The rules require a minimum gauge for a given breaker size. However, gauge works the opposite way from what you might think; 14 AWG is smaller than 12 AWG.

So, yes, this will need changing. Either the breaker needs to go down a notch (and you really don't want to do that, something about wanting full power on drive) or the wire size needs to go to 12 AWG or larger.

Note that this does not apply to the stock motor leads.

You guys did well to make that catch now; you still have a few hours to start fixing it.
