Did my electrician run too small of wire?
Hello. I think my electrician didn’t run heavy enough wire for a long 20 amp circuit. From the breaker box he ran #10 Romex for the first leg of the circuit. The first leg runs into an underground 1 inch pvc conduit 122ft into a j-box. From there he ran #12 Romex back underground, in conduit, for another 129 ft into and outdoor GFCI outlet.
All the online calculators make it look like the circuit needs #6 wire for that long of a pull. A 15 amp breaker would probably take care of that circuit for me, but isn’t the #10 and #12 wire still way too small? Is the electrician way off base and should I raise a stink about it or am I wrong?
