What size conduit is needed to support 200A Mains supply?
(interested in the answer both for copper and aluminum)

Thanks

This is Turtle.

Copper would be a 2 inch and Al. would be 2 inch but for certain type wires and
could even get to the 2.5 inch with some Al. wire types. To know the exact wire
type yopu was going to use would be helpful. Yes I know service entrance cable
but other type can be used.
