Based on the story you documented - I would agree entirely with Mr Mac. That is exactly how it is suppose to work to protect the rest of the system.

If you pull too much current, it will shut down the entire system. Not all fuses or circuit breakers require replacement, when they fail. It is best to know which ones do, and which ones don't.

Usually a single short circuit on an individual line will blow one of the fuses and the rest of the motor driven actuators will remain alive.

If you pull too much current, the main circuit breaker will shut down the entire machine - once the current draw is removed and either time or temperature requirements are met - it will reset itself automatically.
That is what sounds like happened when you were in a pushing match.
