The Circuit Distance Calculator calculates the maximum circuit distance based on the maximum percent voltage drop. This calculator also calculates the voltage drop and the resulting voltage at the load.
Enter the information below to calculate the appropriate wire size.
To calculate voltage drop based on circuit distance, use the Voltage Drop Calculator.
To properly size wire for various applications, use the Wire Size Calculator to determine proper conductor sizing. Visit the Tables page to view reference tables such as Maximum Ampacity for Current-Carrying Conductors.
