Outdoor receptacles located in damp locations require enclosures that are...

• A. Weatherproof
• B. Weathertight
• C. Rainproof
• D. Raintight

Answer: (A)

Moisture protection is the key idea. Outdoor receptacles in damp locations must be enclosed in something that prevents water from entering. Weatherproof enclosures are designed with seals and proper covers to keep water out when used outdoors or in damp spaces, and they stay effective when paired with a listed weatherproof cover. That makes weatherproof the appropriate requirement for this scenario. Weathertight, rainproof, and raintight describe different levels or contexts and aren’t the standard term used here.
