Is there any requirement (Energy, International, NEC Code, etc.) that requires us to air-seal switch and receptacle junction boxes when installed on an outside wall ? This came up in a discussion at one of my contractors' meetings and someone mentioned that one EI is requiring it but didn't site a Code reference. I'm wondering if he just found some obscure Code section that he is not sharing with other EI's or EC's or if there really is a requirement. Also, if there is such a requirement, is there a product out on the market that is ready-made and can be installed without any other means of air-sealing ? Thanks
