I want to install wall sconce fixtures on the outside of my bathroom cabinets. I have power inside from the wall already. Would it be to code if I cut a hole in the cabinet, mounted a metal box, and ran EMT from the wall to the box? See pictures.

    The main problem with your approach is that it will greatly reduce the usability of the cabinet.

  • Yeah, that is a problem. Any ideas of a better way at this point? Apr 30, 2020 at 16:41
  • I'd maybe use flat "raceway" rather than EMT. But that doesn't greatly reduce the size of the boxes.

  • And note that the better option might be to put an outlet in the back wall and run a standard rubber power cord from there to the fixture, with no box on the side wall.

  • You had me at EMT and metal box. No where on Earth is that not ok afaik. It's even in the code that there be an outlet just like that in the lower cabinet at the end of a peninsula. The only problem is when the cabinet isn't permanently affixed, and that's one of the only times I get to use BX (in Chicago; EMT-land).

Yes, when doing in-bench or in-cabinet work like that, I am very comfortable with EMT, provided it is anchored properly and not used as a hanger for other things.


Yes, you can extend the box in the back of the wall with a Raco 665.
