I have some long feeders to buildings that are single phase 240V. It shows on one line that the parallel feeds are maintained from meter to MCB at meter stack then long run on all in excess of 700' to Disconnect on building and from that to MLO on panel. My question is this if they are being run for voltage drop and nothing else, why can they not be one set from meter to MCB and from disconnect to panel MLO. The long distance is where the parallel wires should be taking care of the voltage drop.
