R48 allows Motor Controllers with "Up to 40A" Circuit Breakers. Thus a 30Amp breaker would be compliant when paired with a 30A rated slip ring.

The problem is a 30 amp breaker has much less margin when you get into a pushing match and are monetarily drawing high current. Same could happen running into an obstacle during autonomous. The stall current of a CIM Motor is rated at 131 Amps.

Might be fine depending on the game; but I have no experience running a CIM with anything but a 40A breaker.
