Wiring 8+ Motors

[fredexcels]

So 870 is bagged and tagged, but in one of our cleanup meetings, one team member had a good idea. Without getting into specifics, we need to put on another motor. We traditionally shy away from pneumatics, and so we already have 8 motors running, 4 CIMS, 2 Van Doors, and 2 Fisher Price. Most likely, we'd be adding another Fisher Price. We have the Van Doors running vacuums. It's all done through CAN. My question is can we run the jaguars/Van Doors through the lower current slots on the power distribution block and add the driving Fisher Price motor to a 40 Amp slot without losing too much performance on our vacuums. Thanks.

tl;dr: Can we run van door motors through smaller ports on power distribution with a 30 amp breaker.
