where to put outlet for over stove microwave

[smote]

I'm helping a friend rewire and old house. We've pretty much got everything redone except for the kitchen. He's wanting to put in an outlet for an over the range type microwave. We're do we put the plug in for this? Keep in mind we've stipped the house of all plaster so just the studs are showing right now.
Do I put the plug in the wall or do we leave it hanging for now and install it into the overhead cabinet when it's installed.

thanks in advance.

Well, it's really up to you whether you install a box, or leave a tail hang out of the wall. Guys do it both ways. To mount a box, you'll not only have to let the box stick out 1/2" for drywall, but also for the thickness of the cabinet back and any "dead space" between the wall surface and the finished back of the cabinet. That may have you leaving the box hang out up to an inch beyond the face of the stud. Lately, I've been hanging out a tail, and then putting a shallow wiremold box (V5747) in the back of the uppercupboard to accomodate the receptacle.

We have to put in a dedicated 20amp circuit for over the range microwave oven. We'll be using 12-2 copper wire with ground. Part of the circuit will be on an outside wall due to entire house being almost fully sheetrockd /finished.
We had planned to use romex thru the wall where the breaker box is and in an attic crawl space. Is it true that romex can't be used through plastic conduit on the outside wall, so for that portion, we must switch to single strand 12 guage wire?? :eek:

You'll have to use UF cable instead of NM (romex) because it is going to run outside and I am assuming it will be exposed to weather. The UF looks just like NM but is sealed inside and made for outside use. It costs some more but not that much and is not as flexible.
If the UF is placed high enough on the wall (around 8' and higher appox.) you don't need to run it through anything providing it cannot get damaged at that height (if your standing 2 X8's or 10's on that wall you'll have to protect it). If any part of it is lower on the exterior wall it is ok to place it in PVC to protect it as long as the PVC is used as 'sleeving' only. In other words, don't connect the PVC so that it makes a complete enclosed conduit run. The circuit for the MW has to be 20A dedicated (nothing else on it all the way back to the CB) using a 20A rated recpt.
If you're going to run a complete PVC conduit system, you can use the UF but the PVC has to be at least 3/4" for 1 UF wire. I suggest 1" PVC as the UF is stiff and harder to pull through pipe (you might want to use some lube depending on any bends, etc.).

This all depends on the cabinet location. Yet, the normal rule for me is 81" off the floor, to the top of the box. I leave the box out 1 inch from the wall to account for cabinet.

Just my input.
