WCW Voltage Drop Calculator

The Windy City Wire Voltage Drop Calculator is a user-friendly tool designed to help you quickly and accurately determine the voltage drop in your electrical circuits. By selecting the conductor material (copper or aluminum), choosing the appropriate wire size, and inputting the voltage, phase, circuit length in feet, and load in amperes, you can easily calculate the voltage drop, percentage voltage drop, and the voltage at the end of the circuit. This ensures your installations meet safety standards and perform efficiently.
