Although your current electrical “box fill” may meet code, it’s not safe to jam a new device in if the box is already full of wires. You have two options: Add a plastic surface-mount extender box (like Leviton No. 6197-W; available through our affiliation with amazon.com; Photo 1), or remove the old 12.5-cu.-in. box and replace it with a flush-mount 20-cu.-in. box that’s 7/8 in. deeper (Photo 2).
Have the necessary tools for this DIY project lined up before you start—you’ll save time and frustration.
- 4-in-1 screwdriver
- Cordless drill
- Drywall saw
- Electrical tape
Avoid last-minute shopping trips by having all your materials ready ahead of time. Here's a list.
