Voltage Drop Calculator

This calculator uses K = 12.9 circular mil ohms per foot for copper or K = 21.2 circular mil ohms per foot for aluminum.

These values assume a conductor operating temperature of 75 degrees C. For other values of K based on conductor temperature use the advanced voltage drop calculator.
