However, Gold Star for having been the first to notice this discrepancy in quite a while.

I noticed the "problem" when the team was trying to put the wrong size connectors onto the motor leads. If you use 12 wire from the controller, you need to use a yellow connector, with the blue connector for #14 wire from the motor. The alternative is a terminal board and spade connectors of the correct wire size. I do not think the thermal characteristics of the insulation is (or should be) a factor in determining the size of the circuit protector.
