I have the following example information how do I determine the watts required.
208Voltage, 3-phase PhaseA=14.8A, PhaseB=9.6A, PhaseC=14.7A the rated kVA for this cabinet is 4.71, can you show the formula you use as well -- I have some answers, but I am not sure I am doing the math correctly

I get 4695.5 Watts. But it's been a long time since I did these calcs. Do you agree?

P= 3sq rt. VI cosphi
where
P is power in watts
V is voltage
I is current in amps
cosphi is 0.8
root3 since it is in three phase
