[QUOTE="Andy™, post: 55729, member: 2012"] really need more info on this. even assuming PF of 1, i get 14.45A BUT: if it was 10KW and not 10 KVA, i get 16A so working on that 10/0.9 = 11.11KVA ......................................kVA X 1,000 Three-phase amps = ----------------------------------------- ........................................ 1.732 X Line to Line voltage so 11.11x1000 / 1.732 x 400 = 16A per phase or, the even easier way KVA / 0.692 = A per phase so 11.11 / 0.692 = 16A (the 0.692 is the 1000, 1.73 and 400 all into one number) or at least i think this is right [/QUOTE]
