I need to fish the electrical wire in for a plug to be located above the fireplace in our den for our TV. Since this is an exterior wall, behind the gyproc is a vapour barrier and insulation.
My plan was to cut a hole in the gyproc without penetrating the vapour barrier, then use a renovation box (the kind with the ears that snug up against the gyproc to hold it in place) pushed into the hole against the vapour barrier - in other words, the box would push against the vapour barrier and insulation, not go through the vapour barrier.
To fish the wire to the box, I plan to cut another access hole through the gyproc inside the framing for my new fireplace. The wiring would be fished between the two holes, sliding between the vapour barrier and the gyproc. Once inside the framing for the fireplace, I will drill a hole through the floor within the fireplace framing so the line can be dropped down into the ceiling of the garage and on to a power source.
I'm trying to install this in such a way that I don't have extra penetrations through the vapour barrier (since, in my mind, they can be more difficult to repair) and so I don't have to try to drill up into the lower plate of the wall from the garage ceiling (since its 15' in the air and gyproc'd in to keep the floor in the room above warm).
Anyone see any code issues (or other logistical issues) with what I'm trying to do?
