Hi, I'm Mike G and I'll be glad to assist you. It would be easier to give you the information if you told me how far you want to go.
You need to give me s specific distance from the pole to the house, not 200 ft more. More than what?
There is a program electricians use. Knowing the distance, type of wire and size of the required service it calculates the wire size. I need the distance you want.
You'll need 400MCM Aluminum for that distance. A 400A system would need 500MCM, so you can use what was speced for 250ft.
You're welcome. Let me suggest that you do the service in PVC conduit.to avoid a failure in the future. Cheap insurance.
