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.</div>
