reason #214 why buried J boxes are bad

[ericsherman37]

Working on a remodel of a motel in town here... we're basically going from room to room relocating some light fixtures and adding some dimmer switches and such. The carpenters are going ahead of us cutting big squares out of the wall so we can rough in our fixture boxes and wiring.

I walked into one room and found this:

The box was buried in the wall and he ran his skilsaw right through it. Fortunately he was smart enough to have us turn the circuit off beforehand. I don't know who installed this thing (probably the hotel maintenance crew) but this is not good. I hope there's none elsewhere.

I would expect one in every room that is like that room. :smile:

Ye Gods! How deep are the carpenters setting their saws? 4"?????

If the wall is 5/8" thick, then they should set their saws to 3/4" and no more. Keep this up, and they'll hit water, drain and sprinkler lines........

The walls have 3 layers of 5/8" sheetrock plus a layer of sound-damping board. They're the shared walls between rooms.

I have no idea why there's so much sheetrock piled on there.

I did do some work in a hospital ER remodel a couple years ago, and they had their structural steel wrapped with 4 layers of sheetrock. Something related to 9/11 and the World Trade Center steel softening under heat.

If this rooms a rockin'......

If THIS room is rocking, it's a major earthquake! That's a lot of gypsum; almost 2".

Probably both for fire rating and sound.

If you cover the boxes it's easier to get by without a raceway

And there may be more. Why do people do the things that they do?
