[QUOTE="Tom Manchester, post: 98876, member: 82"] Re: UL listings for XLR & speaker cable? Well, the speaker cable could potentially carry voltages higher than standard wall current given modern amplifier output, however the concern is probably because of the lack of fire rating for standard SJ or similar cable. You wouldn't want the cable to overheat somehow and burst into flames in the wall, or serve as a "wick" to get fire into the wall if there was a fire in the room. Also in some cases I think it has to do with the noxious fumes released by burning cables. Install cable is generally rated for the application and if you are running it through a hole in the wall, you'll likely need to seal around that hole with an appropriate fire retardent material such as the one 3M makes. Your cables should probably be running through conduit as well. If they are going through a "plenum" space, you need plenum rated cables too. Of course this all varies by state and city, so ask your electrician or inspector what's up to code. [/QUOTE]
