Buying Guide: outlet boxes

Frequently Asked Questions

AI
New work boxes are designed for fresh construction where walls are open, allowing direct mounting to studs. Old work boxes feature spring-loaded clips that grip the drywall from the front, making them ideal for retrofitting electrical outlets into existing walls without cutting large holes.
Plastic outlet boxes are generally safe for residential and commercial low-voltage and standard 120V applications. They are non-conductive and rust-proof. However, always verify that the box is UL listed and check local building codes, as some jurisdictions may require metal boxes for specific commercial uses or high-heat environments.
Box size is determined by the number of wires and devices you plan to install. Each wire and device takes up a specific volume. Most standard single-gang boxes hold up to nine 14-gauge wires. For more complex setups with multiple cables, you may need a larger 2-gang box or a deeper single-gang box to prevent overcrowding.
