I have many stud walls in basement remodel that stand in front of poured foundation basement wall faced with foil-faced fiberglas insulation. Rather than drill all the studs to run Romex horizntal from outlet to outlet, I would like to just run behnd the stud (between the stud/foil-faced insulation/wall gap) as there is plent of room. Can this be done and if so how to secure ? I was thinking of putting a loop ever < 4.5' and stapling it to the stud, or just drilling here. Or just space the outlets 4.5' and achor < 8" there. It will be a lot quicker, please advise.
