Buying Guide
- Box size and capacity: Choose a volume that accommodates your fixture’s wires, connectors, and any canopy or mounting hardware. Pendants often require more space than standard outlets.
- Old-work suitability: For retrofit projects, select boxes labeled for old-work installation to minimize wall damage and ensure secure mounting.
- Material and listing: PVC boxes are lightweight and corrosion-resistant; metal boxes offer higher strength. Ensure ETL or UL listing for code compliance.
- Grounding: If your fixture requires grounding, prefer boxes with ground lugs or robust grounding paths to meet safety standards.
- Installation ease: Consider models designed for one-person installation and those with built-in cable clamps or multiple knockouts for flexible wiring.
- Depth and clearance: Low-profile or shallow boxes save space in tight ceilings but may limit wire routing; verify fixture canopy and wire length.
- Compatibility: Check compatibility with fixture type (pendant, fan, or light) and with non-metallic-sheathed cables as specified by code.
