    Calculate Watts
    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
