Tnx for the reference. That led to a search and it's always interesting to
study the NEC. Some smart folks are behind it.
Aside from damage due to overfill, is the fill limit meant to insure no temp
derating is needed? I wonder if one would have to employ large diameter
conduit that would make the act cost prohibitive.
Wrong forum to discuss at length but a question - is NM covered with blown in
insulation required to be derated for ampacity? Off list reply ok.
Tnx

The NEC does not prohibit type NM from being installed in conduit (as long as
conduit fill limits are not exceeded) and, in fact, requires it (or other
protective means) in 334.15(B) for certain installation conditions

I believe the issue is conductor heating. Sheathed cable has to be in open-air

person I've ever encountered that would be even close, would be Mike Holt...

It would be much harder to pull than individual conductors and it would be a
waste of conduit fill capacity. > Running twisted separate conductors in
conduit would not be. Right. And if it's steel conduit, twisting is not
important. 73, Jim K9YC _______________________________________________ RFI
