Look at 334.10(3).
"THWN coating". . . that's a new one on me. Do you have a link, possibly?
NEC 2014, Article 334.10(3) says permitted types III, IV and V. However I am confused with scenario in my original poster in mind 334.10(5) says types I and II is ok as well?
Yeah, if you want to install conduit and then pull cable. Kinda defeats the whole purpose of using cable. The raceway/conduit has to be a type permitted for the type construction also.
(5) Types I and II construction where installed within raceways permitted to be installed in Types I and II construction.
No, no link allowed. All we need to know is that NM-B has 90C conductors. No one ever should know what is really inside. Like the recipe for Coca Cola...it’s a secret....
Exactly what kind of raceways would be permitted with NM cables Types I and II? Also, does the article still apply if it has type II and then B at end same as type II?
This is how conspiracy theories begin. . .
I think it would be a scary thing to go looking for what's buried in back yards in Tennessee.
I think it began with something about GFCIs inside PVC boxes being buried in backyards somewhere in Tennessee...:angel:
