I am building a small home form a pole barn. I am in the process of adding power and have a question about the wiring and code compliance. Usually wiring is run before insulation but due to the way the engineering required the framing to be set I will end up with an 1 1/2” gap between the framing and the final location of the sheet rock. I am going to fill the void with vertical 2x4’s so that I can then Sheetrock over the top of those. My question is can I run my wiring behind the vertical 2x4’s and over the insulation in that void space? I have attached a picture with some creative shapes attached to try and explain. In the picture the grey lines are the future 2x4’s and the black box is an outlet box and red being wiring.
Any help would be appreciated.
