Frequently Asked Engineering Questions
What size copper wire do I need for 60 amps at 200 feet (120V)?
To stay within the NEC recommended 3% maximum voltage drop for a 60A load over 200 feet one-way at 120V (1-Phase), you need 1/0 AWG copper wire. This produces a voltage drop of 2.93V (2.44%) and delivers 117.1V at the load.
What size aluminum wire is required for 60 amps at 200 feet?
Using aluminum conductors (75°C rating), you should use 3/0 AWG to maintain voltage drop at 3.04V (2.53%).
What breaker size is needed for a 60A continuous load?
Under NEC 210.20(A), continuous loads require a circuit breaker rated at 125% of the continuous current (60A × 1.25 = 75.0A), which corresponds to a standard 80A circuit breaker.
