Notice the rusted out conduit, and the rusty strap on the LTFMC! This is located under the first level of a parking garage where exposed to the weather. Is this a wet, or damp location?
I think that leaking water from above on what was once a coupling, has rusted away entirely.
I would think it would be considered a wet location, sincce it is underground. When I see stuff like that, the old addage comes to mind, 'The trouble with electricity is it almost always works'.
Damp, It is not subject to a steady stream of water or rain.
Corrosive does not mean wet. Go open a few walls near the ocean where metallic conduit was installed...it not there anymore, but its not a wet location.
