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:
-
Replace the cover plate with a 4-11/16" cover with openings for 2 duplex outlets and mount the outlets to that.
-
Add a 4-11/16" 2-device mud ring, mount the outlets to that, and reuse the existing cover plate.
-
Replace the box with a smaller 2-gang 4" box, mount the outlets to that, and reuse the existing cover plate.
-
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.
Best Answer
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.
