Okay, it is in a unfinished basements with bare concrete walls. The circuit i want to tap into feeds six lights ( 60 watt incandescent pull chain) and one smoke detector. All running into the basement, it feeds nothing else. I need to drill through the floor, the base of a built in, through the side of the cabinet, into a fake chimney( 2x 4 framing covered with particle board) then out the front of the particle board into a box for the receptacle. Approximately 12 feet, or 40 feet too the panel box. The circuit feeds a 60 flat screen tv only. Their is presently a receptacle in the cabinet wired from the ceiling so i can not get to that circuit. The tv will draw maybe an amp. I originally wanted to run from the panel but it is full. My electrician was the one that said to tap the light circuit. He retired a few years ago so I always double check him against someone with a current license.
