This was an existing SE built with 200 amp (2/0 cu) line side and 100 amp SEC load side of the meter socket. The customer (I work for Alliant Energy in SE Iowa)wanted to upgrade to a 200 amp load panel and do it himself, since an electrician costs too much. Using a licensed electrician would have saved him money in the end. New meter sockets in our area now require horned bypass on residential, and a lever bypass on commercial.
