What Size Wire for 60 Amps at 150 Feet?

At 150 ft, the default 60 A answer makes its first distance-driven jump: 4 AWG copper or 2 AWG aluminum, with voltage drop governing both materials.

What Size Wire for 60 Amps at 150 Feet? under common non-continuous defaults: THHN or XHHW-2 insulation, 75 C terminations, 86 F ambient, 240 V single-phase and no more than three current-carrying conductors.

What 150 ft ChangesAt 150 ft, the 60 A series crosses from termination-governed sizing into voltage-drop-governed sizing under the page defaults. The result moves from 6 AWG copper and 4 AWG aluminum at 100 ft to 4 AWG copper and 2 AWG aluminum here.

150 ft Is the First 60 A Upsize

Mid branch / light feeder context for 60 A at 150 ft.

A 150 ft 60 A route often appears after adding garage offsets, EVSE placement, spa location, equipment-pad routing, trench bends or a small shop feeder path. It is the point where the measured route can no longer borrow the 100 ft result.

Under the defaults, 100 ft still matches the short-run platform. At 150 ft, both copper and aluminum move larger for voltage drop, and the 200 ft page moves again.

What Changes This Long-Run Answer

Checks that matter for distance-governed sizing in this amp band.

  • Do not reuse the 100 ft result

    Under these defaults, 100 ft and 150 ft are different 60 A answers. Measure before ordering conductor.

  • Check 200 ft if the route can grow

    The 200 ft page is not a plateau. It moves again to 3 AWG copper and 1 AWG aluminum under the same assumptions.

  • Use actual operating current

    Voltage drop follows the current that flows. A configured EVSE or equipment load below the breaker handle can change the result.

  • Keep 120 V separate

    The displayed page defaults are 240 V single-phase. A 120 V circuit at 150 ft should be run in the calculator.

60 A at 150 ft FAQs

What size wire for 60 amps at 150 feet?
Under the defaults on this page, start with 4 AWG copper or 2 AWG aluminum. Voltage drop governs both distance-adjusted results.
Why does 150 ft change the 60 A wire size?
The 100 ft page stays on 6 AWG copper or 4 AWG aluminum, but at 150 ft the default voltage-drop check pushes both materials larger.
Can I use the 100 ft answer for a 150 ft route?
Not under these defaults. Use the measured one-way conductor path; 150 ft lands on larger conductors than 100 ft.
What happens if the route is closer to 200 ft?
Compare the 200 ft page or rerun the calculator. Under the same defaults, 200 ft moves again to 3 AWG copper or 1 AWG aluminum.
