For a home generator, to supply voltage for devices that require 220 V or 240 V. An electric oven or clothes dryer are examples of such devices. The generator at the power plant actually generates electricity at a much higher voltage, for easier transmission (and those are 3-phase generators).
Also most homes run on 240 single phase. Power is split at the breaker box. To supply 120 loads and 240 loads. 240 single phase is a common voltage.
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
Yes it would work pretty well but it might not meet its accuracy specification.
The generator should be about ¾ hp.
Yes, but the motor's horsepower rating will not be reached.
You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
62.5 amps

Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.
You will need a 50 kW generator for a single phase 120/240 volt service.
No you need a Roto Phase
It depends upon the Generator system voltage. For 3 Phase, 600 Volt system, it will be 73 Amps For 3 Phase, 480 Volt system, it will be 90 Amps For 3 Phase, 208 Volt system, it will be 208 Amps
