Question

Built-In (back) Oven Clearance for NM Cable?


I'm installing a new single built-in oven into our existing wall cabinet, while maintaining the required physical cabinet clearances, according to the manufacturer of the oven-- 24" front to back, etc.. I am concerned about the NM power cables feeding this oven. Will they be protected against the heat of the oven? They are now coming out of the wall about a foot higher than the base of the oven or oven support. What temperature can I expect to find at the back of the oven in the cabinet? There is a tight clearance for the NM cables (2) of only about an inch or less. Can the cables touch the metal plating on the back of the oven, or must I re-route these cables for preventing fires there (melting of cables)? Thanks in advance for your response!

They do get pretty hot in the back but they do have some clearance however follow the manufacter insturction where is the termation location and I will suggest that you reroute the cable to diffrent location AFAIK most will ask for bottom of the oven which genrally the safest spot for NM cable.

It the same methold with our European wall ovens.

Merci,
Marc

The installation instructions for the oven should show where the junction box should be. Besides the cable issue, putting it somewhere else might mean the oven won't slide in all the way.

Yes, thank you for your response. I went ahead and re-routed my NM cables to where the junction box is. I feel much better about it now. I had to remove a patch of dry wall to move this stiff cable, but not much trouble for me since we do much dry wall install anyway. The installation manual instructs me to locate the junction box below the oven support, so I did.
Thanks again for your suggestions!
