Reno, we could widen this thread to all the changes in the 2008 code but it wouldn't be a thread, it would be a rope. Do you disagree with all changes? If not, let's take one at a time. Also, as a matter of fact AHJs do make changes for individual cases. What is suitable for North Alaska may not be suitable for South Florida.
The NEC is not a mandate. What is mandated could be discussed with your AHJ and your engineers. Also, residential electrical service is only a small part of the NEC, Why not discuss cranes, welders, load transfer in hospitals? If we did in a single thread they would come and arrest us for making criminal demands on human attention span.
