I scoured the code and couldn't find anything that imposed
*different* restrictions on CMP in "air handling spaces" vs.
*ductwork*.  But, I'm looking at an old code book -- I'll
have to make a run to the library tomorrow.

I'll probably either run the cables (CMR) down the *outside*
of the ductwork *or* omit them, entirely (see my reply to
Harry).  Though it would be good to know if there are tighter
constraints on "in ductwork" vs. in "air-handling plenums"!

Thx!
