    This is best left to an electrician.

    Depends on the load etc.

    Before beginning any electrical work, read carefully through a series of detailed instructions. Ensure that you understand them all before starting. Inform other family members or those present of the sort of work you will be doing, and ask that they refrain from turning on any circuit breakers or switches until you've finished.

    Next, turn off the main breaker. Be sure that there is no power flowing to any of the wires you will be working with. Wearing rubber high-voltage gloves and using rubber-handled tools is also critical.

    To convert 3-phase to single-phase power, you can use a phase converter. This device can be wired to the motor you plan to run that requires single-phase power. Note that this will impact only the device wired to it, not an entire outlet because it is not hardwired into your electrical system.

    Run two wires from the motor to the converter. Then, run two wires from the converter to the power supply. With the ends of the wires stripped, connect the inputs to the outputs. Be sure to run a grounding wire from the power supply to the grounding screw of the converter, as well as to run another wire from the converter to the grounding screw of the motor. You can use a voltmeter to use the voltage of the wires. If you are unsure about any step of the process, you should request assistance from a professional.

    If you want to convert a 3 phase ac into 1 phase ac, then take one wire from any of the 3 phases ( R, Y, B) as the line and another neutral as the return wire. But if the ac system is delta connected, then you can first convert it to DC by the rectifier and then convert it back to 1 phase ac by inverter or transformer.
