Right. The NFPA doesn't have any authority in itself. It is a
private corporation. Local municipalities adopt the NEC at their own
discretion.

Exactly,
Another fine example of how the Code works. Anyone out there have
the definition of "special permission".
Any changes have to go back to the NFPA? Really the buck stops at
the quasi-judicial authority of the head of the building department.
Inspectors are the bearers of that authority. So it all comes downs
to anyone can do anything if they can get the AHJ to sign off on it.

Friends:
It is my understanding that local AHJs can implement more
stringent code requirements and can interpret ambiguous citations,
but they can not waive specific code requirements without special
permission. (NEC 90.4). I don't know what is required to obtain
"special permission," but I do doubt the wisdom of local official
attempting to rewrite the NEC.
The original question was a request for help interpreting a code
section. While it is unfortunate that the NEC is not perfect, we
are bound by it's provisions and need to understand the difference
between analyzing the NEC and adhering to it. I hope we have not
further confused the questioner by side tracking to discussions of
wishful thinking that we can convince a building official to
ignore sections of the NEC that we disagree with.
There are forums to express opinions on the validity of code
sections and to propose language, the Solar ABCs being one option
(http://www.solarabcs.org/).

PS: No one commented on the idea I presented of down-sizing the
feeder breaker. This idea requires analysis of the loads to prove
viability, of course, but is likely much less expensive than
pulling bigger wire.

Most of the inspectors I've dealt with are at least somewhat
reasonable. A few are fundamentalists for their own
interpretations. I'd at least show the inspector the email with
Bill Brook's statement and discuss the logic of the
situation. It is obvious that the intent was to protect a wire
that was double fed and could overload. The AHJ has the
responsibility for interpretation of the code, so can allow what s/he sees fit.
