I have recently moved a range, microwave combo and was looking to check my set-up for any errors.

We have removed the oven and cabinet and the old supply line (10G m3 wire) and pulled it back through to the basement. We have the cabinet in its new home and had plenty of the old supply wire to reconnect. We had to come up through the floor with the supply, and came up through the back inside of the cabinet. We stripped most of the outer insulation jacket and ran the bunch of wires through a 4-5ft section of flexible metal conduit 3/4" thick that extends from the floor opening all the way up through the inside back of the cabinet. This attached to the metal junction box that we removed from the old location that the whip remained attached to from the old layout. (the old supply line came through the wall and was just insulated wire connected to the range whip). The range wires were reconnected in the same fashion as before-red to red etc. The box was capped, and oven re-installed in the cabinet. The oven and micro work.

My questions:
1-Any concern with leaving the paper that separates the ground wire inside in the bunch, or with simply leaving them as a bunch? Should they have been separated? Did I need to remove the insulation to prevent overheating?

2-The old layout did not attach a ground to the metal box, and I left that out as well. Any problem with that?

3-Any way to check this out other than a tripped breaker?

I am interested to hear any other info I need to consider..

Thanks in advance

My questions

My responses are in red, following your questions:


1-Any concern with leaving the paper that separates the ground wire inside in the bunch, or with simply leaving them as a bunch? Should they have been separated? Did I need to remove the insulation to prevent overheating?

Leaving the paper wrap on the ground is not a safety issue of any kind, only a workmanship issue. An electrician would have removed it, just because it is not needed.


2-The old layout did not attach a ground to the metal box, and I left that out as well. Any problem with that?

All metal boxes. cable etc, need to be grounded.


3-Any way to check this out other than a tripped breaker?

I do not know what this question means.

I am a bit confused, did the #10 feed just an oven, and remains just feeding an oven? How is the micro and range fed?

All wire is contained in some sort of raceway and splices contained in covered junction boxes?

Wouldn't connecting the grounds together be enough grounding?


3-Any way to check this out other than a tripped breaker?

The #10 makes one connection to the back of the oven, I guess it distributes power to the micro and oven inside


All wire is contained in some sort of raceway and splices contained in covered junction boxes? Yes, the flexible conduit is my raceway, the splices are made in a junction box
