*Note*

This Voltage Drop Calculator for Wire and Cables is for general use.

The actual ampacity and voltage drop for your particular application may differ from these results but in most cases will be very close to those shown here.

To determine the voltage drop for a Motor or Transformer Circuit and like equipment, see the Voltage Drop Circuit Analyzer Module (coming in fall 2023) found in EDM's subscription program.
