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.
For a 4000-watt generator, you typically need a circuit breaker rated between 20 to 30 amps, depending on the voltage. If the generator operates at 120 volts, a 30-amp breaker would be appropriate, while for a 240-volt setup, a 20-amp breaker is often suitable. Always check the generator's manual for specific recommendations and local code requirements.
A 5500 watt gas powered generator typically requires a 30 amp breaker for a 240 volt connection. It is recommended to consult the manufacturer's specifications to ensure the correct breaker size for your specific generator model.
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.
For a 200 amp breaker box, it is recommended to get a generator that is at least 22,000 watts to provide enough power to cover the peak load. This size will ensure that your essential appliances and circuits can be powered during an outage without overloading the system. It is always best to consult with a professional to determine the specific needs of your home.
To determine the size of the breaker needed for a 78 amp range, you typically need to use a breaker that is the next size up from the amp rating. This means that you would need an 80 amp breaker to safely accommodate the 78 amp range. However, always consult with a qualified electrician to ensure the correct breaker size for your specific electrical setup.
Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp breaker.
For a 4000-watt generator, you typically need a circuit breaker rated between 20 to 30 amps, depending on the voltage. If the generator operates at 120 volts, a 30-amp breaker would be appropriate, while for a 240-volt setup, a 20-amp breaker is often suitable.

The question isn't the number of amps total on your branch circuits, but rather, what your MAIN breaker(s) are rated at. This will determine what size of generator you will need. And be certain that the generator is 3-phase. <<>> The formula you are looking for is Amps = kva x 1000/1.73 x voltage.
50amp but if considering the breaker cannot withstand starting current you need to size the breaker up.
For a 30 amp breaker, you will need a wire that is at least 10 gauge in size.

Prices vary for a Yamaha Generator depending on the size of the generator. The more wattage involved, the more you will need to pay. First you need to determine the size of generator you need then contact a local retailer.
For a 50 amp breaker, you will need a wire that is at least 6 gauge in size to safely handle the electrical load.
For a 50 amp breaker, you would typically need a 6-gauge wire.
Click the link. There you can figure the size generator you need.
if you have 200 kva so it's 160 KW then ,you need 400 A MCCB and setting at 0.9 and use cable 4c.185 mm2 if the SMDB is nearby and all this will be change according to the ambient temperature and the electrical code used in your area
