Question: 1 / 400

What is the maximum weight a fixture can have if supported by an adequate outlet box?

25 pounds

40 pounds

50 pounds

The maximum weight that a fixture can have when supported by an adequate outlet box is determined by the type and design of the outlet box itself and its mounting method. A properly rated outlet box designed for supporting light fixtures can typically handle up to 50 pounds. This weight limit applies specifically to boxes that are securely mounted to structural elements of the building, such as joists or studs, which ensures stability and safety.

When installing fixtures, it's essential to check that the outlet box is appropriately rated for the fixture's weight and usage to prevent damage or accidents. Other weight limits may apply in different configurations, such as ceiling-mounted fixtures, but for standard electrical outlet boxes, the 50-pound limit is widely accepted. This is why 50 pounds is the correct answer in this context.
