Hello. I just received a wall oven with a whip line that is made of 1/2" non-metallic sheathing with 4 separate conductors. The conductors appear to be no larger than 10 gauge and occupy less than half of the sheathing volume. I would like to route the line up and behind the oven within the cabinet, but the sheathing is a bit too thick. I have 8 gauge romex (correct number of conductors & NM-B) that would fit perfectly but wonder if there are temperature issues or other reasons to reject the idea. Thanks!

Yes there are temp issues.
That is the reason the wire is a smaller gauge then you have to use to feed the oven with.

The whip is made to connect to a junction box where the building wiring connects to it. The instructions will tell you where the box can be located.

Be sure to put a connector on the end of the flex.
