Thanks to all who replied with code references. I think we have put up a good argument and refuse to re-locate the five separate combiner boxes down at eye level on the top parking area of a student parking deck. Just an accident waiting to happen. However, in researching this issue I noted that the 2008 code and the comments I am hearing about the 2011 code still are not clear about combiner box requirements. I agree with Bill Brooks that on single array residential systems it does not make sense to put the combiner box on top of the roof and require a ladder to access, but on large commercial systems where there are already multiple code required disconnects that are required to be accessible, I still think its best for the installer and for system maintenance to have a disconnect mounted in the cover or right beside the combiner box at each array on multiple array systems.
