I don't have my 2014 code book yet. I have been told that table 310.15 (B) (7) is not in there any more. That's the single phase dwelling service and feeder size table. It allowed us to use 4/0 aluminum SER for a 200 amp breaker panel. Does this mean that we will be forced to use 250 SER for these dwellings now? My inspector said there is going to be an IAEI meeting next month and they will be addressing this issue. He did say that 4/0 would still be allowed except where it passes through insulation. What will be the article that address this issue, and how is it allowed or not allowed? He doesn't know how this will shake out yet. Am I missing something? Thanks.
