Like the medicine cabinet I paid for - it's a 14" X 19" hole on the bathroom
wall (I guess the shelves and door were additional options they forgot to

A guy I ran across once actually had this happen to him. the medicine
cabinet they left him was a mirror hanging inside a stud cavity with a shelf
under it made of drywall.

The code makes an exception to safety grounding switch based
upon no exposed conductive parts.

No - the only exception is for replacing a switch when
there is no grounding means available at the box. In new
construction you must ground the switch.

I don't have the copy.
