I installed a behind tv wall hole so i can plug my tv in. Now in trying to decide how to run power to it but I'm not an electrician. I know that you can wire an outlet off of an existing one, but is it safe to run the cable up to the attic and back down a stud over? The issue is that the closest existing outlet is one stud over from my new outlet. I figured if i could just run it up and over, i could easily supply power to this new outlet. Rather than running it to a junction or something (again, not an electrician).
