[QUOTE="Rob Timmerman, post: 64809, member: 172"] Re: Restaurant audio System Except that the wiring in use is UL listed as type CL3R, which is appropriate for the use at hand provided that it is not being run in a space used for environmental air (see Article 300.22(c) for locations that need plenum ratings. One such example is the space above drop ceilings that gets used as a return air plenum, but is not specifically constructed as such). It's certainly possible, and indeed likely, that this installation is using the cable appropriately. And given that the installation has been approved by the AHJ, I'm going to guess that's the case.
