I have a customer that wants a 400-amp service for a house he is building. The 400amp service with meter has 2-200 amp breakers then 2-3? pvc conduits run 300 feet to his new home and then going to 2-200 amp disconnect switches outside the home and finely ending up in 2-200amp main lug panels inside the home.
My question is wire, I am planning to run 2-350 and 1-4/0 aluminum URD in each 3? from the main service to the disconnects on the home for voltage drop do I need to run a ground wire? Or can I use the concrete encased electrode at the disconnects? Any input would be appreciated.
