The manufacturers had nothing to do with 300.9. 300.9 was a code change proposal of mine to clear up the question as to whether the inside of a raceway installed in a wet location is also a wet location. CMP-3 acted on my proposal and said that the inside of such a raceway is indeed a wet location.
In this case we now know it wasn't. In the field blaming the manufacturers for something that may not make initial sense is a common practice - probably rarely true in actuality.
Conceptually I still have issue with requiring the inside of a raceway, on the side of a building, with raintite fittings, all components installed to code, being called a wet location.
Perhaps being in a dry state like Colorado has affected my perception in comparison to moist southern and eastern states, but out here if you install a conduit on the side of a building with raintite fittings, there isn't any moisture inside the conduit unless you put it there or the installation failed in some way.
In practice this whole debate doesn't mean a whole lot for me, I don't like installing NM in a raceway anyway. Hard to pull, takes up way too much space, don't want to argue with inspectors as a general principle.
Thanks for contributing to my knowledge tool kit, thanks for helping to improve the code.
