Hi guys, I have an Eaton CH42B200 that was installed in 2009 before I bought the house. I've rewired and ran into difficulties placing breakers because the electrician who installed it left the main breaker at the top even though it's fed from the lower-left, directly through the wall from the meter. The 4/0 aluminum SE wires prevent AFCIs from fitting in the lower positions.
I have all the cables terminated and grounds neatly connected (the picture is a bit old) and would like to lay in the breakers and button this up before the weather gets colder. It would save me a lot of time if I could have the meter pulled for a short time and then flip the bus over, versus fighting with it as-is or replacing the entire thing which would take all day. I know in the 100-amp CH subpanel the whole panel must be rotated and not just the bus. But is that also the case with CH 200-amp panels? Is there an easier way out?
