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.
You need a 60 amp breaker.
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 1500 watt generator will do fine.
ranch style home - 1500 square foot with partial basement. What size generator would be needed?
Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp breaker.
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.

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.

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

You need a 5.5kw generator to run a 5.5kw motor.
A 1500 watt generator will do fine.
