Need a little help with calculations: I've taken voltage, amperage, watt & PF measurements for each phase of a 440V 3 phase/ 4wire panel with an Extech power quality clamp meter. The measurements were made by measuring each line to neutral (not between the phases). Now that I have all the individual line readings, I want to calculate the total amount of watts and amperage being used on this panel by all 3 phases.

My measurements were:

L1: 260V, 60A, 12.20KW, PF-76

L3: 268V, 56A, 11.10KW, PF-74

L3: 263V, 52A, 10.80KW, PF-79

How can I calculate the total amount of amps & watts being used on this 3 phase panel?
