Is the inside of conduit ran indoors a wet location?

But is the interior of a conduit installed in a damp location (e.g. some regions under a covered porch) itself a dry location? I didn't find anything in the NEC that contradicts that idea. : - )

Exactamundo, and well said.

I do have a bit of inside knowledge on 300.9....I wrote the proposal

I heard some guys arguing on another forum about it. Got me to thinking. The question is not about under the slab, we all know that's a wet location.

For example, If you have 2 inch or 3/4 EMT ran on racks above, inside a dry building. Is the inside of that conduit a wet location? Would you be required to pull THWN ?
Somebody said it is a wet location due to temperture changes and condensation.

What say you?

Wasn't much of an argument, only one was of the opinion that it was wet.
