I am trying to help an older lady that somebody did wrong while trying to wire a garage. They took and welded the main 100A breaker on her box to the aluminum bus bar. Anyway I am installing a new 200A service and it is in her basement. Do I have to hard pipe all of the romex coming out of the breaker box until it gets to the rafters in her house? The panel will be mounted on the basement wall. Thanks for the help.
