There is no need for an exception. Even in the 2008 NEC, 690.31(E) is
clearly about the dc wiring. The proposed informational note adds
nothing except to explain that ac isn't dc.

There is an proposal in the pipeline for NEC 2014 that makes an
exception for AC PV modules after the wiring enters the building. See:

FWIW: In the 2011 Code, Section 690.31(D) is changed to include
the following:
"Where dc photovoltaic source or output circuits...are run inside
a building or restructure, they shall be contained in metal
raceways,/Type MC metal-clad cable that complies with
250.118(10/), or metal enclosures..."

Hello wrenches,
wondering if any of you are running into inspectors wanting EMT
in the attics, or allowing flex only if there is a fusible
disconnect on the roof. We have heard this a few time lately and
havent yet seen a code reference, (except 690.31e saying metal
raceways are fine- not specifying EMT only). I am wondering if
this is a new wave of inspectors wanting the future now as
informed by an expert seminar, or if there is something I am not
aware of. Any comments are very appreciated.
Thank you,
Nick Vida
