Voltage Drop Calculator


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