Operating a breaker on a continuous current, close to the breaker's tripping point can cause this condition. Because the breaker is a thermal device the heat builds up over a time period. Check the breakers on either side of the faulting breaker. If these breakers are also warm from use they take away the heat sink effect and do not let the faulting breaker cool down. Check the current of the load to see how close you are operating to the breakers trip point. Over time the trip setting of the breaker can become lower to a point where it will not reset. Changing the breaker out should rectify this non resetting condition.
Breaker point contacts are made of silver plated copper.
The ambient temperature does have an effect on the tripping point of a breaker. If a breaker is operating at near capacity the additional ambient temperature will lower the breaker trip set point.
To scout
What power point? Is it a fuse or a breaker, they are not the same. What do you want to know?

I don't understand the question. <<>> If your generator's main breaker does not trip when an overload occurs on the generator's output the breaker's trip setting needs to be looked at. Usually the molded case breaker's face cover can be removed. This will allow you access to the trip settings. Set the overloads to the maximum generator's output. The short circuit setting should be set at 250% of the maximum generator output. If these parameters can not be met on the existing breaker there might be a chance that the breaker has been changed out at some point in time and the wrong breaker was installed at that time. This scenario happens quite frequently on remote operations where the service has to be maintained and the site doesn't have a second back up generator. The site supervisor usually says "just make it work".

The neutral is in contact with the ground at some point of the circuit.
