Solve for Wire Size

Wire Size = #3 for 120V, 24A, 400 Feet

Solve for Voltage Drop

Software calculations are performed using nominal 120V

Voltage Drop = 19.2% for 120V 24A, 400Feet, #10Wire

This software package provides a Feeder Efficiency Tip as follows (Amperage used = 8A instead of the 24A shown above.)

Solve for Available Current – Amps at 5% Voltage drop)

This Software Voltage Drop Calculator indicates a maximum Current of 6.035A at 5% V Drop. Over 400 ft. Of #10 Wire.
