Buying Guide
What should you consider when selecting a round ceiling box or outlet?
- Box type: Old-work boxes are ideal for retrofits; new-work boxes suit new construction. Choose based on installation context and retrofit goals.
- Wiring space: Check cubic inches and gauge capacity to ensure enough room for conductors, clamps, and the chosen device.
- Depth and mounting: Some boxes are shallow; ensure depth fits your ceiling thickness and fixture weight.
- Material: Plastic boxes are lightweight and easy to install; metal boxes offer durability and often better grounding paths.
- Grounding: Verify grounding provisions and screws; some boxes include grounding lugs or plates for safer installations.
- Device compatibility: Decide whether you need a simple receptacle, a cover plate, or a specialized fixture for ceiling fans or lights.
