I have a small back yard and only two outlets. One by the refrigerated air unit on the side of the house and one on the back porch. My back wall is about 20-25 feet away and I would like an outlet on that back wall. The outside outlet is recessed into the stucco wall. Would I just find a.box to bring it out and get some conduit that would tie into the bottom of the box then run it to where I want an outlet?
