WebMay 17, 2024 · The system I am working with is commonly 208V/120V 3 phase in wye configuration. 208V * 200A * 1.732 [sqrt (3)] gives me about 72,000 VA theoretical power output of the service. If I were to connect 200A of load on each leg to neutral (120V) I would be pulling 72,000 VA. 200A * 120V * 3 phases = 72,000. WebThe formula used to determine the capacity for a three-phase connection of 230 V or 400 V is identical, i.e.: √3 x U x I. So, for instance, if you have a 25A dispenser in place, the maximum capacity is to be calculated as follows*: 3 x 230: √3 x 230 V x 25 A = 9947.5 VA 3 x 400 + N (eutral wire): √3 x 400 V x 25 A = 17 300 VA 23品牌
