Dry or damp?

[bill1952]

Porch with roof (ply, ice and water, architectural shingles) and ceiling. LED down lights in ceiling. NM-B or UF?

Thanks.

Dry location.

My vote is for damp location NEC definitions
Location, Damp. Locations protected from weather and not subject to saturation with water or other liquids but subject to moderate degrees of moisture. Examples of such locations include partially protected locations under canopies, marquees, roofed open porches, and like locations, and interior locations subject to moderate degrees of moisture, such as some basements, some barns, and some cold-storage warehouses.

Location, Damp. . . . roofed open porches

I take that to refer to wiring exposed within the user portion of the roofed open porch, and so possibly directly exposed to moisture from the side. Whereas I understand the OP to be about wiring in the porch's "attic," which would not be so exposed, and hence would be a dry location. Like any other attic.

Cheers, Wayne

Is a porch with a ceiling - creating an attic as wwhitney suggests - and "open porch"? Clearly no exposed, just not conditioned.

I did find both damp and wet LED fixtures. Soffit lights being key term. Fewer choices than dry.

Thanks for the discussion. My preliminary search suggested it was clear cut.

I concede, I missed the ceiling.

What about the light fixture? I have not considered a light fixture in a porch ceiling to be in a wet location. The policy has been that unless it can be rained on, it is not a wet location and we just never paid much attention to a damp location. Every bathroom with a shower could be damp.
