Can 6 AWG carry 60 amps?

For 60 ampere breakers, electricians and professionals suggest using a wire size gauge ranging from 6 AWG to 4 AWG. All household wires have a rating of at least 600V, so only amperage really matters when it comes to determining wire gauge. Therefore, the wire size for 60 amp 220v, for example, is still 6 to 4 AWG.

Can number 6 wire carry 60 amps?

This is the best size wire for 60 amps and 50 amps. However, with a 60 amp wire, you can go sometimes use a 6 gauge wire if it is only a short run. Use THHN or RHW type insulation.
