Can a 230 460 volt 3 phase motor be connected to a 277 480 volt 3 phase circuit?
How can you run 415 volt 3 phase motor with 220 volt 3 phase?
Can you use 240 volt single phase to run a 208 volt single phase motor?
This is a 15% overvoltage to the motor, which is generally outside the specifications for a motor spec'd at 208v (typically up to 10% overvoltage is tolerable). Your 240 volt source may be as much as 105% of 240 / 252 volts at times. A buck/boost transformer should be used, unless the motor is designed to be used at 240 volts.

Can you convert 240 volt to 208 volt?
I'm sure you could, but it wouldn't be practical. The reason for this is because 208 volts between two phases comes from a three phase transformer, while 240 volts phase to phase comes from a single phase, center tapped transformer. If you're asking regarding a resistive load, such as a heater, the load should work with 240 volts or 208 volts. There will be a slight difference in performance, but it shouldn't be very noticeable. If you're asking because you have a motor load rated for 208v, you'll likely see that the motor requires three phase 208 volt power and you only have 'two phase' 240v power. You can however supply a three phase equipment or motor with a device called a phase converter.
How many Amps for 3 horsepower at 208 volts?
For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.
