I upgraded my house from 100A to 200A 5 years ago. I buried 3" conduit from the pole to the house. I was told the 3" would support 400A. At the time I did not have the money to install 400A, so I just thought I could find a 400A panel later. I do not think they make a residential 400A panel, and from what I have seen it uses two 200A panels.
I am still wanting to put 400A service to my house, to try to cut on my electric bill. ($565.00 last month).
In the 3" conduit, do they use 6 wires for the 400A to a two 200A meter pan, or use larger wires to a 400A meter pan?
I probably will get the call an electrician, but I feel as though I can do the install, just wanted some info on how it is done.
Thanks.
