What Size Wire for 60 Amps at 200 Feet?

Answer
3 AWG copper

At 200 ft one way on a 240 V circuit, 3 AWG copper keeps voltage drop at 2.45%, under the recommended 3%. Ampacity alone would allow 6 AWG, but voltage drop decides the size at this distance. In aluminum, use 1 AWG.

    Voltage drop by wire size (60 A, 200 ft, 240 V)

    Voltage drop = 2 × 200 ft × 60 A × resistance ÷ 1000. Keeping it under 3% on branch circuits (5% total) is the NEC recommendation in the informational notes to 210.19 and 215.2.

    Frequently asked questions

    Is 6 AWG enough for 60 amps at 200 feet?

    It carries 60 A, but at 200 ft the voltage drop is 4.9%. That is over 3%, so the next size up is recommended.

    Does the distance include the return wire?

    No. Enter the one-way distance; the formula already counts both conductors.
