The formula you are looking for is 460 divided by the square root of 3 (1.73).
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.

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.
In a 277-volt circuit, if you measure the voltage from Phase 1 to ground, you should read approximately 277 volts. This is because 277 volts is typically the line-to-ground voltage in a three-phase system where the phase voltage is 480 volts. Therefore, when measuring from the phase conductor to ground, the voltage remains the same at 277 volts.

No, a 2 pole breaker is designed for a 240-volt circuit or for two separate 120-volt circuits that are out of phase with each other. For a 120-volt single-phase circuit, you would typically use a single-pole breaker.
No, a single-phase oven cannot be wired to a three-phase circuit without a transformer. The electrical systems are incompatible and may result in damage to the oven or the circuit. It is recommended to use the appropriate circuit or consult with a licensed electrician for proper installation.
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.
Yes, GFCI devices are available for use on 240-volt, 480-volt, and 600-volt circuits. They come in different voltage ratings to suit various electrical systems and provide protection against electric shocks by quickly shutting off power if a ground fault is detected. It's important to ensure the GFCI device is rated for the specific voltage of the circuit it will be used on.
A zero volt rail is a rail that is connected to 0V... What do you think it is? The 0V rail is often used as a common ground, although obviously it relies on your ground voltage being 0V.
