Is there a suggestion for what type of NM conduit to run in higher temperature environments like an attic, or do I need to stick with metallic conduit?
I’ve searched around, but can’t find a good solution for this. For background, I’m running CAT6 in a residential attic (2 story, single-family home). There’s a section of the attic that is a real pain to access, and additional LV cables will be pulled through there over time. So, the client wants a conduit to span the approximately 15’ leading from the 2nd story, into the attic, and to the more accessible area.
I’d like to stick with flexible NM conduit, but ENT and similar products can only be used up to ambient temperatures of 122F, and the attic might exceed that. LFNC is rated for higher temps, but it’s an odd use of it. I’d like to avoid FMC since it would require running a ground. The conduit can be properly secured along its length.
