Calculating load of a 3 phase generator

Hi All,

I have a 3phase 208/120 V generator with associated currents of 50A,
20A and 20A. How can I calculate each load in kW?

Many Thanks,
Kevin

You don't mention the power factor of each current leg.

But total power would be something like....

P = 120V*50A*pf1 + 120V*20A*pf2 + 120V*20A*pf3
