I was told by my supervisor that all 3 phases are drawing the same current and the overload "should" be set exact to the current.

What I was told happens that when a log gets jammed in the canter, the breaker trips immediately. There is no delay of a few seconds before the breaker trips. I believe the breaker is 2000 Amps, and the current draw from the canter is close to that. To get over this tripped breaker situation, would it be safe to put in a slightly greater breaker size or will this burn out the motors too fast? I do not know the whole situation, but if a breakers job is to stop current flow when there's a problem, I don't want to tell my supervisor that this is the only option to fix this situation. I'm not sure if they can modify the intake to the canter either. I was wondering if anyone had any other ideas or options.
