AV code - speaker wire, cat 6 etc

[redcoat]

Hello!

We’re in Raleigh, NC and expanding an event space.

Where can I find the code for running speaker wire and cat 6? It’s a type 2B building and open ceiling 17’ to deck.

Many thanks!
David

What does "open ceiling" mean? No ceiling, exposed roof deck and framing?

Oh, my bad, yes exposed to metal beams and all the way to deck.

This is a snippet showing the poor job the hvac contractor did running thermostat wire! Hope it plays ok. Ceiling is about to be painted black.

Hi, would love some input here!

No ceiling ==> no plenum ==> no requirement for plenum-rated wiring.

Don't be insulted - this is a 101 fast overview. While I work on a lot of projects where all a/v working except 120 v is in conduit for protección and future changes, most is not required to be. Unless through a plenum, most a/v wire is fine. A plenum is an enclosed uninhabitable space used for air distribution. Most typical a space above a hung ceiling i'm some buildings. Through a plenum you need plenum rated cable - less flamable jacket.

Last - support it well but don't support it from sprinkler system. I see ir supported from other conduit but that to may be prohibited - I don't know.

No offense here, I appreciate the response.

I was under the impression that we didn’t need anything plenum-rated until electricians said they needed to use it for low voltage wire for lights with 0-10V dimmers. Figured I’d verify here!

I’ll try and find out why they said that.

But you asked about speaker wire and CAT6 data cable ...

Right - I figured low voltage was low voltage… guess I should have been clearer from the get go

It looks as sloppy as usual. The code doesn't say anything, except for what it's supported from, but the Owner or A/E might.
