200 AMP direct burial wires ( 350 Ft Long runs) | Electrician Talk

300ft, 200amp feeder run. What size wire would you run
2021年5月4日 · 300ft from disconnect to panel. 200 amps. My calculations show 350 mcm Al for 3.46% vd. The client has a buddy that is a master electrician and is telling him to run 250/250/ (4/0). I'm suggesting 350/350/350 as it's a long run and I don't think derating the nuteral is worth the few bucks of cost saving.

SER Cable in Conduit - Electrician Talk
