Does foil flex touching 12/2 or 10/2nm wiring constitute a violation of the electrical code?

i haven't been tagged on it yet, but I aways take pain to keep it two inches or more away. Electricians who come behind always run there wire against it.
A conversation with my son-in-law. He is a union electrician and a very good one at that. I didn't think to ask him at the time, but thought about "clearance to metallic objects" later. By the way, I like most of your postsYou seem very good.
Well thank you sir!
I would have thought that clearance to metal is related more toward metal framing, or things that could cut and tear the exterior PVC sheathing on the romex. Which is why I use MC on all commercial jobs.
What your son in law WILL run into, if he hasn't already, is physical touching of romex wire (or any other plastic), to Blazemaster (orange sprinker piping).
They (Code council, or whoever writes this junk) have decided that the plastic in blazemaster will deteriorate if it comes in contact will any type of other plastic related material.
We ran black plastic flex in that particular set of appartments, and we had to get a letter from the manufacturer of the flex, showing that they had done testing related to blazemaster, and that it was allowed to "touch".
A large project (the banks project here in cinci) actually saw deteriation of blazemaster, at the point of contact.

I wish we could still even run flex here! What a nightmare those changes caused for attic jobs.
I was thinking about shorts or induced voltage that might occur from nearby lightening strikes.I've seen where lightening has induced voltage in wiring and jumped to metal duct.

The only code provision that I can think of is that the wiring must be protected from damage. I doubt that contact with flex duct is likely to cause damage to NM cable.

I've seen an example of it. Just don't remember where.

I will be glad too. It seems it had something to do with lightening charging a gas line then duct work.

I don't remember, but it seems like we were talking about bonding and grounding csst. I'm trying to remember. I'll call my son-in-law tomorrow to see if he remembers. It may have been a csst booklet I read.
