I'm looking at a Voltage Drop calculation. In this case circuits 1, 3 and 5 (i.e. phases A, B and C) plus neutral (shared) and ground are ran together in 3/4" conduit to the LED's, which operate @ single phase, 120VAC and draw 48VA or .4A. I am treating each circuit as a single phase load even though all three phases are ganged together at the lighting panel board, three phase 4W, 120/208VAC. Is this correct?
