Class 2 wiring method for lighting

[FVC]

I'm installing several low voltage recessed LED lights that have remote mounted Hi-Lume Lutron drivers. I am having a difficult time trying to find the proper stranded conductor to run between the driver and the fixture. Would I be correct in assuming that if I use a in-wall rated class 2 (150v) or a in-wall class 3 (300v) speaker wire for these fixtures it would be done as per the code?

Is this a residential application?

Yes, multi family building.

My 2017 code change for TC cable addressed this application in which the committee stated "the proposed language does not add any addtional information" so my conclusion is that no change was needed to use TC cable is this application.

So you would not use speaker wire but you are recommending Tray Cable?

speaker wire is not compliant per 400.8 niether is exterior lo volt light ug cord.

So confusing because the wire says it's listed for Class 3. My Lutron driver is listed for class 2. Is the code book it says that all class 3 could be used for class 2.

See the link for the wire I'm referring to

The particular speaker wire you have presented will not be in the table of article 400 -- Is rated as a CL3 see Figure 725.154(A)

This is a non-plenum space. So, as per the figure on 725.154(G) this wire could be used for my application?

Have you considered installing the newer Type MC-PCS products that incorporate the Class 2 conductors and normal power conductors in a common Metal-Clad Cable?

I guess if you are not using Type MC in this project it would be a pain to do so.....but just in case.

That type of wire is for 0-10v dimming only. The lights I'm using are forward phase Lutron high lume drivers. I need to get my secondary conductors from the remote mount drivers to the LED drivers.

Ahhh..gotcha

It's fine. Any cable listed CL2 or CL3 can be run within structures (but not plenum or riser). Further, just because somebody is calling it "speaker wire" means nothing- except that you are probably getting ripped off on cost. Go ahead and use it but consider that there is other 14/2 CL2 wire out there that is probably cheaper. -Hal
