Understanding voltage drop: the voltage available at the load can differ from the source voltage because conductors have resistance. Voltage drop is the reduction in electrical voltage as current travels through conductors. A common US electrical design guideline recommends keeping voltage drop around 3% on a branch circuit and 5% across the feeder and branch
