I'm going to install an exterior receptacle by running a non-metallic (NM-B) cable from an interior receptacle. I will be installing it just on the outside wall right behind the interior receptacle. The cable will exit through a hole in the exterior stucco and into a metal box made for outdoors. Then I will install an exterior rated receptacle with a receptacle box.
I will use duct seal (kind of like a gray putty) to seal around where the stucco hole meets the exterior box hole. I will also take the proper precautions to caulk the perimeter where the exterior box meets the stucco.
Will I need an outdoor/exterior (UF-B) cable to run to the outdoor receptacle?
