Dumb question?

Please don't ridicule me for this question because i gotta ask it, OK? Is it in any way OK to pass NM cable perpendicularly through a central heat duct if i send it through a pvc conduit?

The only reason i can imagine this could be all right is that i know that my attic gets way hotter in the summer than heat duct ever will in the winter and I also know that you can do this across a cold air return duct. lil help here? anyone?


I'm gonna hurl myself against the wall
because I'd rather feel bad than not feel anything at all

No and No....

No, it's not a dumb question....and no you can't pass it through the duct....the hot air 'could' damage the wire...

Though I seem to recall a similar thread where it was ok under certain conditions....maybe it was the return duct....
Even if you are on the right track, you will still get run over if you just sit there.

Why not just run it beside it?
I would highly doubt the heat would be the issue, it's where it exits and enters the duct where there could be issues as well as the possiblity of a noise issue with the wires loose in the duct work.
