Which of the following is the maximum allowable weight of a fixture directly attached to an outlet?

• A. 10 pounds
• B. 30 pounds
• C. 40 pounds
• D. 50 pounds

Answer: (D)

Weight rating for fixtures attached directly to an outlet box is the key idea. Outlet boxes and their mounting hardware are rated to support only a certain load, and that limit is 50 pounds for a fixture attached directly to the box. This ensures the box and screws won’t pull out or fail under the weight, which could cause the fixture to detach or damage the wiring. If a fixture weighs more than 50 pounds, assume heavier loads require additional structural support—such as a fan-rated box or a brace that attaches to the building framing—to safely bear the weight. This prevents safety hazards and keeps the electrical work secure.
