My POCO has requested a single line diagram for the new 3 phase 400 amp service I intend to install.
I have never done one before.
In the past we just install using one of the methods outlined in their blue book.
What information are they looking for?
Just a block diagram showing the lateral, meter channel, building wall
and two 200amp parallel load centers?
