Re: Experience With 6 Cim Drive train

I think the idea is it's harder to stall with lower CoF on the wheels. However if you do stall anyways, you have the same problem.

4476 ran a 6 CIM at a 13-14 ft/s theoretical. We never popped a breaker, and I suspect it was a combo of lower friction wheels, and we put a couple of breakers on the PD board for the drive CIMS at 30A instead of 40A. The idea being that the PD breaker would trip before the main breaker would.

I'm not really sure which made a difference as both were implemented prior to testing to make sure we never blew the main breaker, but it makes sense to me that both would have had a significant factor in preventing main breaker trips.
