FRC motor controllers can easily deliver current well above 40 amps, which in short bursts wont trip the pdb breaker immediately, but if your cims are sitting stalled on the bridge, it is likely that this is your problem. This could be due to the gearing ratio also, and the motors not having enough torque to keep driving up the bridge. Maybe consider a change in your gearing ratio.
