Which term is used to describe the weather-tight cap installed on top of a service raceway?

• A. Cap
• B. Junction box
• C. Duct cap
• D. Weather head

Answer: (D)

The term describes a weatherproof fitting that seals the top of a service raceway to keep moisture out where the service conductors enter from outside. A weather head is designed to shed rain and protect the entrance point, forming the weatherproof transition from the exterior raceway to the interior equipment. A generic cap isn’t specific to the service-entry context, a junction box is a weather-tight enclosure for splices or terminations rather than the top-cap for a raceway, and a duct cap is used for air ducts, not for service raceways.
