Is there a code-legal way to conceal a box?
I'm putting a small bathroom in the corner of a finished room. Where the back wall of the tiled shower will be is a receptacle box. It's in the middle of a run so whatever I do with it means I will have to worry about what's downstream from it. I know all about why you don't bury boxes, so I was prepared to take out some pretty big sections of drywall to rewire. However, I have a friend in the construction trade and he said that it is now legal to conceal a box under certain conditions as long as the wires in the box are connected with some new kind of splice/crimp.
Can someone please comment on whether this is in fact true/legal and, if so, where can I find some more info?
