A rain-tight service head is also called a __________.

• A. Cap
• B. Weather head
• C. Weathercap
• D. Roof cap

Answer: (B)

The standard term for a rain-tight outdoor point where service conductors enter a building is weather head. It sits at the exterior entry and provides a weatherproof seal so water cannot enter the conduit or the building while allowing the conductors to pass through. That’s why it’s described as rain-tight—the hooded design channels any moisture away and keeps the interior protected. Other options don’t fit because they aren’t the recognized term for this component: a generic “cap” lacks the specific function and location, “weather cap” isn’t the standard terminology used in practice, and “roof cap” refers to vents or openings on a roof, not the service entrance head.
