The generator circuit breaker or gcb is a circuit breaker which is connected with the generator . Whenever there is a fault in the generator the circuit breaker trips and disconnects the generator from operation thus it helps the place from a serious accident etc..
If it is a portable generator the breaker should be self contained within the generators panel. If the generator is a stationary standby unit a voltage has to be stated to calculate the conductor size and hence the breaker size to protect the conductor. Amps = Watts/Volts.
It won't supply any power.
The cable that is used to connect from the generator is based on the size in kW's of the generator and the generator's breaker size rated in amps. It usually is a flexible cab-tire 4 wire cable if the generator is a portable type. If it is a stationary generator is has to be wired with a flexible conduit so as not to transmit vibration from the generator to the conduit system.
You would size the generator to match the main breaker size rather than on the sum of all the breakers. The main breaker size depends on the specific model of the circuit breaker panel - 100 Amps is typical for a house. The main breaker protects the circuit panel's bus bars from overheating, and the bus bar size is what limits the maximum power through the panel. Power = Volts x Amps, so a 100 Amp panel at 240 Volts could be operated by a 24,000 Watt (24 kW) generator. That's a pretty big generator in household terms, so often only a subset of the circuits would be allocated to the generator. Or, you just be careful not to turn everything on when using the generator. The actual Watts used depends on what's turned on, not the generator size or total capacity of all the circuit breakers. If you turn on too much stuff with an undersized generator, the generator's overload protection will trip and cut it off. Or if you load all the circuit breakers to capacity the main breaker will trip. In addition to these basic considerations there are a considerable amount of electrical codes governing connecting a generator to your house. The major one is to have a switch that prevents connecting your generator to the utility input, which precludes you from inadvertently energizing the utility lines.
A breaker should never be fed from its load side to energize the bus in the breaker distribution panel. This question suggests that you are trying to connect a generator to back feed your electrical panel during a power failure. This setup as killed linemen trying to repair the downed primary lines. If the panels main breaker is not opened, the generator will back feed the pole transformer that the linemen are working on and bring the line potential up to 14,000 volts. There are proper change over switches in the market now that will allow you to run your generator and the switch will automatically disconnect the utility connection before making the connection to the house panel. If this is your line of thought, do a bit of research on the subject. The last thing people in the trade want to hear is another lineman getting electrocuted. If the load exceeds the rating of the breaker and the breaker is functioning properly, it will trip.
Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp breaker.
No.
Generator Breaker Status
The load conductor is connected to the load side of the generator breaker. Once the generator is up to speed the load breaker is closed and the voltage is then applied to the load.

If it is a portable generator the breaker should be self contained within the generators panel. If the generator is a stationary standby unit a voltage has to be stated to calculate the conductor size and hence the breaker size to protect the conductor. Amps = Watts/Volts.
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".

circuit breaker is break the electrical circuit .circuit gear is generator analyzer
start generator, plug in variable speed drill, set drill to forward, squeeze trigger, quickly spin drill in reverse by hand. be sure generator main breaker is on.
A 15 KVA - Generator operating at 380 Volts can cater to only 22.79 Amps. It cannot cater to a 60 Amps breaker
so that the incoming generator will not act as load but rather a source that can synch in less time
