NM cable (romex) in PVC

Sierra,

I can live with your Post.

( I pulled my post from info of a past thread,
where we hashed through this,
and I repeated the conclusion for the benefit of discussion. )

IMO,
Practically, most of us strip off some Romex to get at the conductors.
I had not observed a protective nylon jacket on the Romex I have,
and the insulation is thin enough to warrant extra care.

I live in the back woods of Kalifornia sometimes I think I live in scrapsville. I don't have enough digits to count on as to how many times I see Romex pulled in conduit. I am not talking about a stub-out. It's like nobody out here carries single roll wire. They sell is at all the local hardware stores and they even cut it.
Very strange and more expensive.

And by the way the paper is always wet.

Sierra,
The backwoods have enlivened your sense of humor !
Must be something good happening back there.

Around post #30, I got to thinking...My thread would have been closed (due to "argument") by now. Gotta love those MOD's. :grin:

From reading all the posts, would this meet the 2008 code?

Replace the LB with a WP box. Install conduit from the WP box to the disconnect. Run THWN wire in the conduit. Terminate the THWN to the NM conductors in the WP box.

I have no problem with it, some will argue your transition from NM to an outdoor rated wiring method would need to be located indoors.

It really is a can of worms. I find it funny that there must be a magical barrier that separates where the interior of the conduit (wet location) connects to the interior of the WP junction box (dry location). IMHO without some sort of WP barrier between the two, it should be considered a wet location also.

Steve,
Sounds compliant. Mix and Match.
IMO. I don't see where the RX to THHN switch involves a 'damp' consideration.
Only underground conduit, where condensation cannot escape or drip out.
