Also 334.15 for exposed work.
(B) Protection from Physical Damage. Cable shall be
protected from physical damage where necessary by rigid·
metal conduit, intermediate metal conduit, electrical metallic
tubing, Schedule 80 PVC conduit, or other approved
means. Where passing through a floor, the cable shall be
enclosed in rigid metal conduit, intermediate metal conduit,
electrical metallic tubing, Schedule 80 PVC conduit, or
other approved means extending at least 150 mm (6 in.)

above the floor.

This is also NOT new for 2008.

So let me get this straight. NM can only be run in conduit in unfinished basements and crawl spaces or only with short sections of conduit to protect the wire. Is this correct? Scuba Dave said that you can use larger conduit to run NM in. Is he correct with this or not.

Its been a while since I have looked through the NEC handbook. I need to get a current edition.

Maybe not totally The 2008 also has a new rule about conduit installed in a wet location. The interior of a conduit in a wet location is to be considered a wet location. NM cable is not allowed in a damp or wet location, also an underground or underslab conduit is considered a wet location. NM (romex) would not be allowed in these conduits.

You could have misunderstood or forgotten one of the parts he told you. Then again maybe not.
Give him the benefit of the doubt or at least ask to clarifly.

Even though I still have more schooling to upgrade some of my inspection certifications (Electrical Im finished with I can go no higher with certifications and liscenses in that field my speciality) Im working on Building ,Plumbing, Mechanical, and Fire, We still have continuning ed and then there are the Code changes every year. You always can and have to learn if you want to continue to grow and not vegitate.

Well I've got a long way to go and try to learn everything i can from people with more know how than i. As i try to teach those with less knowledge. Absolutely right. Am a member of several forums to learn from others.
