Works as described Derek below said you need to multiply by 1.73, which is incorrect assuming you enter phase to phase voltage (which is standard). He must have entered phase to ground voltage. This app works.
Doesn't tell you that you need to multiply by 1.732. Might want to know that too. App works though.
