Installing a New JB for Range Hood
Hi folks. I ripped out my old range hood (original 1960's vintage, non-venting, VERY nasty). I am replacing it with a new ducted/non-ducted hood.
The power comes from an old 2 conductor cable with a copper ground wire, that just sticks out of a hole in the wall, located above the backsplash over the cooktop. The old power cable was terminated directly to a block inside the old range hood. I just cut the old range hood away at the the power cable. So now I have the exposed cable (capped with wire nuts) sticking out of a hole in the wall.
So, to do this right, I want to install an actual junction box to hold any extra cable and the wiring from the range hood. I plan to use wirenuts to connect the power to the leads on the range hood.
I've started trying to open up the wall around the hole where the cable sticks out. It was a real job because my house is all gypsum board with a plaster veneer or plaster on lath. Finally, I've got about a 3x4 rectangle cut out. The cable is stapled to a stud behind the wall. My plan is to remove the staples and mount a jb to the same stud and pull the old cable through it.
My question is, what is the appropriate type and material to select for my junction box? Are there any special criteria that come into play when selecting the right jb for this application? Steel or plastic?
