Which code reference requires suitable marking on a luminaire used in damp locations such as under a canopy covering a walkway into a building?

• A. Article 100
• B. 410.10(A)
• C. 110.11
• D. 408.10(A)

Answer: (B)

Luminaires installed where moisture can be present must show that they’re suitable for damp locations. Under a canopy that covers a walkway into a building, the area is exposed to humidity, rain splash, and condensation, so it’s considered a damp location. The NEC requires the luminaire to be listed for damp locations and to carry a marking indicating that suitability. The specific code reference that sets this requirement is Article 410, section 410.10(A). This clause ensures that fixtures installed in damp locations have the appropriate marking or listing to verify they’re rated to withstand moisture, helping prevent electrical hazards and corrosion.
