Calculating Voltage Drop in Power Distribution Systems

When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code requirement. The first belief is false, but the second is only partly true. For sensitive electronic equipment, branch circuits can't have more than a 1.5% voltage drop, and the combined
