Carl,
The reason that I don't think that the generator breaker will trip is that in many cases it cannot supply enough current to operate the OCPD in the short time trip part of the breaker curve so the generator will try to supply the load and the prime mover will likely stall.
A long time ago a mechanical engineer told me that his engines are smart and our motors are dumb. The motor will try to supply what ever mechanical energy that is required by the load or will die trying if the load is too much (assuming that it is not properly protected), but the engine when it is overloaded just says I quit and stalls out.
