Under 2023 NEC 410.10(A), which requirement applies to a luminaire in a wet location?
- A wet-location marking and installation preventing water from entering or accumulating in electrical parts
- BA 15-ampere circuit alone

Why A is correct
The required wet-location identification and water-control installation conditions both apply. Circuit rating, height or added sealant alone does not establish suitability. Follow the product’s mounting and sealing instructions; do not assume every wet-rated design requires drain holes.
