Where something is installed decides what you are allowed to install there, and "under cover" is not the same as "dry".
The three categories look like common sense and are not. A covered porch and a sealed indoor room are both "not in the rain", and they are not the same location classification.
The one people miss is the inside of a raceway. A conduit run outdoors is exposed to changing temperature, and moisture gets in and collects where nobody is looking at it. So the question is not just "is rain landing on this" -- it is what the conditions are inside the installation as well as around it.
Check yourself: A box is under a covered walkway, protected from direct rain. Is that a dry location?
Answer: No. Protected from direct rain does not automatically mean a dry location.
The classification is about the conditions the installation is actually subject to, not about whether rain is falling on it at this moment. Moisture reaches places that are covered.
