20 AMP power to motor controllers?

If you do decide to put a CIM on a 20A breaker, just remember that the breaker is there to protect the wire, but there's still a chance of the high current burning out the wire before the breaker trips if the motor stalls. The AWG requirement in table 4-3 is just a minimum, so feel free to go higher in this case.

As far as I know, there hasn't been a rule limiting certain motors to breaker sizes. The rules dictate the minimum wire gage that can be connected to a certain size breaker.
The CIM's stall current is 133A at 12V.
