This document discusses voltage drop calculations for electrical circuits. It notes that the total voltage drop is equal to the voltage drop in the heaviest loaded active conductor plus the voltage drop in the neutral conductor. The document also provides a reference to additional information on voltage drop calculations in the Electrical Trade Principles textbook by Hampson and Hanssen.

3. Vd = Voltage drop in the heaviest loaded active
+ voltage drop in the neutral
