I need to run a 30 amp, 120 volt service about 180 feet. What size and type cable do I need to carry the amps and distance?
The type of cable will depend on the work you intend to do. It will also depend on the load on the work you intend to do. Therefore, it is best that you contact and consult an electrician for more information on the best cables to use.
I'd go #8 direct burial. #10 is standard for 30amp
Is it residential or commercial? #10 or #12 should do depending on fla's.
