How can I fix the mounting of these outlets in this box that is taller than the outlet?

Question

I have 4 outlets in my garage mounted in an exposed box where they do not seem to be centered. (This seems to be a 4-11/16" box.)

Removing the cover plate reveals that each pair of outlets is only mounted to the box by one corner, which seems pretty sketchy.

How should I fix this so that the outlets are mounted properly? It seems like I have a few different options:

1. Replace the cover plate with a 4-11/16" cover with openings for 2 duplex outlets and mount the outlets to that.

   

2. Add a 4-11/16" 2-device mud ring, mount the outlets to that, and reuse the existing cover plate.

   

3. Replace the box with a smaller 2-gang 4" box, mount the outlets to that, and reuse the existing cover plate.

   

4. Replace the box with a smaller 4" junction box, replace the cover with a 4" cover with openings for 2 duplex outlets, and mount the outlets to that.

   

Are all of these acceptable options? What are some reasons to prefer or avoid any of these approaches? I assume that replacing the box would be more work since I'd have to disconnect and reconnect the outlets. If it matters, each pair of outlets is on a separate breaker, and I am in the US.

Answer 1

Given that your box is surface mounted, #1 (domed cover) is the correct answer.

Converting to a 4x4 box is way too much work. Using a mud ring (even a flat one) with a cover plate will create sharp edges to snag things.

Noting that 4-11/16" boxes have plenty of room for GFCIs and such, if your garage is wanting for a GFCI on that circuit/those circuits, here's your opportunity!

While you're at it, fix the grounding defects. The installer has the grounds going to the receptacles. No. The grounds go to the metal box FIRST. Once that's done, the grounds get to the receptacles one of several ways. If you properly mount the receps in the domed cover, they will pick up ground via direct contact domed cover to box and direct contact yoke to domed cover. That takes care of it, and you don't need to run a ground wire to the receps.

Answer 2

All your listed options will work.

1. Folded edge covers always fit a bit wonky, unfortunately they don't make a crushed corner version for 4-11/16" boxes
2. Gap between faceplate and mud ring that looks incorrect, possible hazard
3. A lot of work, 4.5" face plate will extend past edge of box, less hazard
4. A lot of work, will look the best, possible damage to sheetrock that can be complicated to repair

5th option? Really option 2.1, maybe a flat device ring, a regular sized 4.5" faceplate will mount flush against device ring and be smaller than existing 4 11/16" box. Probably most expensive fix.

Answer 3

Good thing you found this it was not correct.

The first 2 methods are both ok and would depend on what look you want. Code actually requires more than 1 screw for the receptacles.

If you use option 1 you can put all 3 screws in if you like but NEC 110.14.A requires more than 1 for each (to anchor the receptacle).

You can use the 4-0 box and covers your the last 2 options but you don’t have to change the boxes, proper covers will be easier and meet code.

Answer 4

Ideal way to fix that is a tailor cover, the first one you've shown. The bottom one is also a tailor cover, but for a 4x4 box from the look.
