I got a question i'm trying to solve. There is a 3 phase system with a delta motor load and three single phase loads. Part of the question asks to find the line current (so the line current of one of the phase motors plus the current from one of the single phase loads). To find the single phase load current (second wire connected to neutral) i know you would take the kW of the single phase load and divide by 277. But in the book they don't take into account a 30 degree phase shift from going from line-line to line-neutral voltage. Is that because this 30 degree phase shift is only for 3 phase loads? Even though each of these single phase loads are connected to one of the 3 phase system conductors?
