motor stall current vs Victor ratings

We're rookies to FIRST, but experienced with BattlebotsIQ. We've seen the 05 and 06 power diagrams and have a question or two. If the motors draw 80+ amps at stall, the main breaker is only 120 amps, and the Victor 884's only do 40 amp continuous, how do FIRST teams allow for stall conditions? Four motors at stall would exceed the main breaker, and any Victor 884.

In Battlebots we would use higher rated Victor 885's, in parallel if needed, because we had motors with theoretical (if the batteries could keep up with the load) stall currents of near 300 A @ 24v.

1. Are FIRST robots allowed more than one battery?
2. Can we have more than one main breaker in parallel off the battery (if only one is allowed)?
3. Are the circuit breakers provided in the KOP auto resetting? Main breaker auto resetting?

Any other ideas along these lines?
Nervous excitment.
Thanks,
Gooooooooooo Teams!!!
