I saw three robots with tripped main breakers at the Boilermaker regional. In each case, only one of the wires was warm. The apparent cause was not too much current, but simply too much heat from a poor connection caused by a loose nut where the wire connects to the breaker.

Loose main power connections -- on battery terminals, SB-50 connectors, main circuit breakers, and/or Power Distribution Board inputs -- were unfortunately very common. It'll be interesting to see if the logging feature of next year's PDB will help convince certain teams that their general animosity toward "the FMS" is misplaced, and that their loss of robot control on the field can usually be prevented with a bit more attention in the pits to checking and maintaining the robot's electrical system.
