DIY adding power outlet in ceiling or convert range to hardwire?
What aggravates this is that I put marble tiling all across the wall up to the ceiling, and it is now difficult to add a power outlet behind the flue pipe box. The exhaust is in the wall not the ceiling, so in theory I could add an outlet there. But I was wondering if I could, instead, add a power outlet in the ceiling? The flue/exhaust box reaches the ceiling so it'd be out of sight.
I've asked the seller (it was through Amazon) to let me return the hood, and thought to find a hood that uses hard wiring, but I can't find any at all! I found one single used one, but it's underpowered. Under the cabinet hoods do seem to use hardwiring often, but this is a wall mounted one, and all new ones I'm seeing everywhere all use an flexible cord and plug.
However, the seller came back telling me that I could just cut the cord and connect the wires together. Everywhere I read that you can't do that, because it'd void the UL listing. Perhaps, maybe, if the cord could be disconnected completely, and the romex cable might attach to the box that's inside the hood. I consider that still an option, but I'm sure people will tell me off on that.
So, the "proper" route, perhaps an acceptable one, might be:
1) Cut hole in ceiling.
2) Run romex wire behind the wall down into the basement.
3) Buy dedicated breaker box with proper rating (20A?) - its a 800 CFM hood.
4) Insert an old-work / re-work outlet box into the hole. This is the type that does not require it to screwed into a stud. I'm counting on a stud, of course, not being in the right place, because of Murphy as always.
5) Connect romex wire to outlet.
6) Check to see that everything might be in order. If something doesn't work out, cancel and undo the whole thing and noone would have known - and nothing has ever been hooked up, so no rules broken.
7) Apply for permit.
8) Make connections including installing the breaker.
9) Call for the inspection.
So what are the problems with the steps above to add the outlet, and alternatively, what are the problems with following the seller's suggestion to essentially convert the plug in type to a hard wire type?
