I haven't done residential wiring in houses for a couple years. Someone told me that vaporproof boxes are required on exterior walls and on the last floor ceiling? I asked a electrician and he told me that is true per the 2011 code but only on the front and rear walls. I seem to get a different answer depending on who I ask. Does anyone know where they are required and also the section of the code book that its in?
