Question by go redwings: Electrical ground service requirements?
I’m installing underground power to feed a 200A service. Line is running 250 feet. Electrician said 4/0 wire aluminum, but I don’t know if thats’ 2-4s and a 2, or 2-4s, 1-2 and a #4 ground.
Also, what depth does it need to be buried to? What size schedule 40 conduit do I use? And how far from my undergound water line does it need to be?
