romex in conduit or not?

[Cmreschke]

U.F. Cable and Romex are not the same thing. Romex is actually just a trade nam for nm cable (nm stands for non metallic sheath)
Romex was/is a major manufacturer of nm cable. Nm and uf cable are recognized in two different articles in the code book.

People interchange direct bury romex and uf romex all the time!

Really? never heard it called direct bury romex. In Maine its UF

Done what? NM is an assembly, so when you strip the outer cover, you have no idea what type of conductor is left. While it is common to use it as a quick alternative to THHN when none is available, it is a violation. What is hard to believe, is that an electrical inspector would require an electrician (Eaglewolf?) to do this questionable violation to correct the use of NM in conduit, when there is no code reason to do so

We strip the sheathing from the part below the joists that will be inside the pipe,I normally leave between 6" and 1' of sheathing inside the pipe.
If its starting inside of a junction box and continuing through pipe to another box then its done in thhn of course,but youre talking about 2 different situations.

The only way to run romex in conduit is if you use white p v c and white plumbing fittings,seen this way too many times,wonder how long it took?

The Romex name was originally owned by the Rome Cable Co. for it's NM cable.

Now it owned by Southwire, and is copyrighted. Southwire actually issued a memo recently that demanded when the is referred to in a setting such as Forums it be referred to as: Romex®. (alt+0174), which went largely ignored.

NM's construction is completely different than UF cable. UF does not have a paper filler, which wicks water. NM has no protection against UV, and has a tendency for the jacket to degrade when exposed to the rays of the Sun. NM also is not mildew resistant, unlike UF.

It's called UF in California, too.

Actually as alfed pointed out, Romex is a type of nm-b cable made by southwire.

Really? never heard it called direct bury romex. In Maine its UF

Actually, its code name is uf-b but people usually drop the b just the same as with nm-b.

A google search reveals that others call it direct bury romex as well!

It was a joke but also kind of true. I saw some drop cords run through white pvc, probably 150'. The installer cut all the ends off the cords and wrapped the joints in electrical tape (no wire nuts). The pipes were strapped but drooping across the walls in U shapes. We came in, tore it all down, and ran EMT in its place.

Romex® was a brand of General Cable for many years until Southwire bought them they are still the owner of the trademark.



NM-B means it's has 90 degree rated conductors, this change occurred in the mid 1980's but ampacity is based on the 60 degree rating, NM is the earlier marking.

I did the Google search as well. Walmart, Sears, Home Inspector. and DIY Forums aren't really credible sources, much less experts.

Have to agree w/ that.

In the trades, it is common to refer to UF as direct bury and NM as romex, even though it is not correct. But you never hear "direct bury Romex" in these parts.
