Buying Guide: Key Purchase Considerations And Comparisons
- Box type: Old work boxes are ideal for retrofit renovations where walls are already finished, while new work boxes are best for new walls or ceilings where studs are exposed.
- Capacity: Larger boxes accommodate more wiring and larger devices. Choose 14–25 cu in for single or two-gang configurations depending on device size and cable count.
- Material: PVC is lightweight and corrosion-resistant, suitable for most residential installations. Metal boxes offer rigidity but require grounding; PVC often simplifies installation in dry locations.
- Installation features: Look for captive screws, nails, removable tabs, and built-in clamps. These features speed up placement and improve wiring organization.
- Code compliance: ETL or UL listings indicate safety compliance with NEC standards for non-metallic sheathed cables. Verify compatibility with your local code requirements.
- Accessibility and future upgrades: Consider extra space for future wiring or device upgrades such as GFCI or dimmers. Deep boxes support larger modules without crowding wires.
- Color and visibility: Blue or bright-colored boxes can improve visibility in crowded wall cavities, aiding easier identification during installation.
- Compatibility with devices: Ensure the box size and knockouts align with switches, outlets, and brackets you plan to install, especially for 2-gang or 3-gang configurations.
