In wet locations, what cover is required for all 15- and 20-ampere receptacles?

• A. A listed outlet hood identified as 'extra-duty' with a weatherproof enclosure, whether or not an attachment plug is inserted
• B. A standard weatherproof cover plate
• C. A gasketed snap-on cover
• D. A hinged metal cover

Answer: (A)

In wet locations, receptacles must be protected by a weatherproof assembly that keeps moisture away from the contacts, even when a plug is inserted. The best choice specifies a listed outlet hood identified as extra-duty with a weatherproof enclosure. This combination is explicitly rated to withstand wet conditions and provides reliable protection for the receptacle whether or not a plug is inserted. The extra-duty rating is important because it denotes suitability for outdoor or harsh-wet environments, ensuring water shed, durability, and safety.

Other covers don’t meet that required protection in wet locations: a standard weatherproof cover plate alone isn’t enough to shield the receptacle after a plug is in place; gasketed snap-on or hinged metal covers may not be listed for the same level of protection or may not provide the full weatherproof enclosure required for 15- and 20-amp receptacles in wet areas.
