The formula you are looking for is 460 divided by the square root of 3 (1.73).
277 volt
Check for a blown fuse in one of the phase legs.
Question is incorrect. in a 240 Volt single phase circuit, how can you have A phase and B phase?
The 208 volt configuration is one phase of a three phase source at 240 volts, where the 208 volt circuit is connected between the center tap of one 240 volt phase (usually a grounded neutral, in the style of a standard 120/240 split phase system) and the high delta connection on either of the other two phases. 208 circuit would consist of two phases of a 208 volt wye system or could be all three phases. The voltage between conductors would be 208 volts. The voltage to ground from any phase would be 120 volts. A 240 volt delta system would give you a high leg to ground, somewhere around 190 volts and the other two would be 120 volts to ground.
5000 volt
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, in the form of GFCI circuit breakers, not as a receptacle.

Yes, if the motor is rated 240 volts 3 phase.There is such a thing as 240 volt 3 phase power.However if you are asking if you can use 240 volts single phase on a three phase motor, then the answer is no.
yes <<>> No, the ground wire is never to be used as a neutral. In this case if you need a 120 volt circuit from the 220 volt circuit a three wire cable (3C #14) must be installed.
A volt can not be connected to a circuit.
5000 volt
Assuming you are using the correct meter with true RMS you most likely have a loose neutral somewhere in the circuit. Try to measure from hot to ground. If this measures 120V then you most likely have a loose neutral somewhere.

It is limited by the size of the fuse in the circuit.
