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).
There's nothing wrong with this
It's A-OK to run a cable up through the top plate to the attic and back down to the next stud bay as long as the cable is run properly (1.5" setback from the edge of the studs, and run stapled to the top plate in the attic).
