10/2 air conditioner wiring - clarification


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, Dry. A location not normally subject to dampness or wetness. A location classified as dry may be temporarily subject to dampness or wetness, as in the case of a building under construction.

Location, Wet. Installations under ground or in concrete slabs or masonry in direct contact with the earth; in locations subject to saturation with water or other liquids, such as vehicle washing areas; and in unprotected locations exposed to weather.

So if the outside of the conduit is "exposed to weather" that make the inside a wet location?
Where can I find this in the code book? I am curious.

I can't give the citation, but every time someone asks about NM ran in conduit underground, everyone says the conduit is considered a wet location

Yep, and 300.5 (B) covers Underground locations as being wet.

Incorrect- refer to 300.9 and the definition of wet locations you posted earlier.

You're posting about enclosures now, which is a tangent from the current discussion.



For example, the LFMC in this pic is installed in a wet location, and the interior of the raceway is also a wet location.

Philly, I don't have my 2008 codebook with me. All my sections were from the 2011 edition. There is no 310.8 in 2011, so I'm not sure what you're referencing.
