By the way, I'm beginning to think the main breaker should be bumped up in rating from 120 to 150 or 180 amps. While I'm not the electrical expert that some on this forum are, I have a hard time seeing what could get damaged (that's not already protected by a breaker on the PDB or somewhere else) at 180 amps but not at 120 amps. Especially if the era of 6 CIM drives is to continue, teams should be able to compete without the specter of a main breaker reset hanging over their heads.
This is the same thought I had after watching the last finals match. At least two teams on the field were running 6 cim drivetrains because they've become the new high performance standard in FRC. I don't see how First can give us this many cims, and mini-cims, and banebots motors, and anymark motors, and then not expect us to start putting 6 cims on the drivetrain.

33 posted this thread http://www.chiefdelphi.com/forums/sh...d.php?t=125187 a while back that talks about this with far more knowledge than I posses on the subject. But the bottom line is that all the current on an FRC robot goes through a 50 amp connector and a 120 amp main breaker. Either we need to have less amperage available to us, or upgrade to a higher amperage standard on both these components. As it is we're seeing far too many main breaker trips in situations where the cims and the wires attached to them are in no real danger.
