Correct answer to question 7005
- C: One that stays weatherproof whether or not a plug is inserted (in-use type)
Explanation
Section 406.9(B)(1) requires an in-use type enclosure for 15 and 20 ampere receptacles in wet locations, so the receptacle stays protected while a cord is plugged in. The extra-duty listing applies only to outlet box hoods, not to every in-use product. A cover that seals only when closed and unplugged is not enough.
