Luminaires located on the outside of an office building under a covered entryway may be marked as suitable for which locations?

• A. Dry locations only
• B. I or II only
• C. Wet
• D. Damp locations only

Answer: (B)

The locations concept is about moisture exposure ratings for luminaires. Luminaires can be listed for dry locations, damp locations, or wet locations, and some are marked for multiple categories. The terms Location I and Location II come from older labeling where Location I typically means dry locations and Location II means damp locations. A fixture marked as suitable for both I or II can be used in either dry or damp environments.

In this scenario, outdoor but under a covered entryway is not fully exposed to weather, so it’s considered a damp location. A luminaire that is marked as suitable for Location I or Location II is appropriate here because it can be used in damp locations (and also in dry locations if needed). It would not be restricted to dry only, and it would not be rated for wet exposure.
