Hiya..
From the theory, to work out the amperage of a single phase system, you divide the power (P) by the voltage (V) as from the PVI triangle. Is this the case for a three phase calculation.

For example; 1 phase
3Kw motor = 3000w / 230v = 13.04 Amps

Does this same calculation apply to three phase??

example 3 phase;
1 - 3Kw motor = 3000w / 400v = 7.5 Amps or
2 - 3Kw motor = 3000w / 230v = 13.04 Amps

Which is the correct answer?

Thanks in advance..
