Landscape lightoing is being fed from a three phase feeder distribution. Each of the lights fixtures are alternately circuited from the three phase feeder and the lamps operate at 277v, single phase. At each light pole, one of the phases of the three phase feeder is tapped along with the neutral conductor. In performing the voltage drop calcs, do you perform them on a phase to neutal basis for each of the phase legs or treat it as a three phase system?
