yep, that's want as asked the electrician to do but they said the box would be fine. I guess I was right and now I am screwed. I was able to sort of pull the broken piece away from the box and was able to get glue in there and push it back into place. The paint did not break so you can't tell there is a fracture no. So should I trim the drywall beyond the edge of the box so when I put the outlet back on the box will not press into the unsupported edge? If this does not work I am totally screwed, we just had the drywall textured painted and this outlet is below the cabinets what a complete mess.
