In-wall, low voltage wiring requirements

In-wall, low voltage wiring requirements

In-wall, low voltage wiring requirements

(OP)
Is it necessary to use UL listed wiring when installing low voltage wiring (CAT5, Coax, speaker, etc.) in the walls of a home under construction? Can I just use the less expensive variety that is not UL listed?

RE: In-wall, low voltage wiring requirements

Check the NEC.

RE: In-wall, low voltage wiring requirements

Specifically check articles 800 through 830. There are other concerns besides voltage and ampacity such a flame spread.

RE: In-wall, low voltage wiring requirements

All Electrical equipment must be approved for the purpose.
See Article 100, 110, 110-3b. Approved for the purpose means acceptable to The Authority Having Jurisdiction.
Its your license!

RE: In-wall, low voltage wiring requirements

i was just called on this one by an overly nitpicky inspector.  he cited nec110-3b disallowing my removing of the sheathing of alarm wire too far away from the window.  not sure if he's right on this or not but he sure is a pain to work with.

RE: In-wall, low voltage wiring requirements

I would consider if there was a fire and you didn't have an approved wire, could the insurance company deny you a new home. I've heard it happen before from an inspector.
