Does is state in the 2008 NEC that you have to use UF cable to feed an outdoor fixture in a wet location? Thanks in advance, MR. S
Romex in a wet location???

Nowhere does it state you are required to use exclusively UF, as any wiring method approved for wet locations will suffice.
But NM cannot be used in a wet location. 334.12(B)(4).
I may learn the error in my ways, but, if you have a fixture installed outdoors in an unprotected area exposed to the weather, I think we all agree that is a wet location.
If that fixture is mounted to (or supplied from) a box mounted flush in the wall, then I see no problem NM supplyimg that box. Neither the box or the NM is exposed to the weather.
Whe I read the OP, this is what I pictured.
Does anyone look at the scenerio I mentioed in a different light ?

how can the we find out if the fixture box Augie mentioned is in a wet or damp location. It seems that if the fixture is under an overhang that it would be a damp location and exposed without an over hang to be wet; however I can't find any info other than to ask the AHJ to make the determination.

So if your basement is deemed a damp location, and you are into the 2008 NEC, all your wiring for the basement, and any feeds going thru the basement cannot be romex. $$$

As Augie has stated, the box mounted in an exterior wall of a building is "within" the building and not considered a wet location (How many boxes that serve the wall space inside the building are mounted in an exterior wall? Do we call that space within the exterior wall a wet location?). The fixture mounted to the box is located outside and is in a wet location.
NM cable would be permitted to supply the box mounted in the exterior wall as long as NM cable is permitted for the wiring method.

As usual, there is not enough information to determine an answer.

my question was answered, flush box romex, exterior box uf, or approved for wet location

We have had this situation before where a box was mounted on the outside and it was fed by NM cable which at no point was ever exposed to the outside. It went from the inside directly to the back of the exterior box.
That is OK but if any part of the NM cable was visible on the outside then we have a problem.
Your issue is still not clarified. Maybe to you but maybe you are wrong.
Example: Someone in a thread on another forum thought at as long as you connected to any exterior box you had to use UF cable even though no part of it was ever visible or exposed to the elements.
Just trying to help a fellow EC such as yourself.

never happened to me, but I would think a bldg. inspector can make that call.

Can you run uf in a pvc sleeve up the side of a house to the attic. Say 2 lbs and a stick of pipe? Just not nm.

If your basement is a damp location, NM cable is not permitted in '08, '05', '02, '99, '96, '93, '90 editions.........NMC, however is permitted in damp locations.

I think the question you are asking is Can you meet the requirements of 334.30 ( as refered to in 340.10(4) and run the UL up the wall outside.
Are you running the conduit for protection from physical damage or convience?
Answer that question and I guess it answers your question in my opinion.

We do alot or most of the time run NM in pipe. When you have a homerun coming from an outside panel and have nowhere to splice from NM to THHN, what do you do? I have an example in the picture below. It is hard to see in the picture, but the panel next to the meter has a short piece of 2" PvC coming from the top of the panel into the soffit. Now, this PvC was installed to accomidate all needed homeruns for this dwelling.
According to code or from what a read as interpetation <sp> of the code, I am not allowed to run NM through this short piece of PvC due to the fact it is a wet or damp location.

i agree, its not practical to do this...and ill contuinue running nm-b in conduit to the panel....but i see where it makes sense....had an outage the other day, i found that the wire in the emt(it was nm skinned back) had broken... i think they nicked the wire during the pull and years later it finally broke....i got a nice shock when i touched the pipe too(the moron for some reason skinned the nm back at the panel, he cuts the grounds off, and only pulls the current carrying conductors)
