I haven't been out to this job to look yet but anyone recognize this older GE 3R sub panel? I am trying to figure out if it will accept twins all the way to the top of the bus. Home owner says label is gone. Yes I am aware of the incorrect breaker for the AC.
I think you just answered my question....If there are 24 spaces, in order to limit the circuits to 40 only 16 of those spaces would permit twins leaving the remaining 8 spaces for full size breakers only, so I am almost certain that the top 8 spaces will not accept twins. Your reply got my brain into gear and I had a "Duh" moment.
