I use Monster Cable S162 (16 awg 2)and S164 (16 awg 4) for all my own stuff it is UL RATED CL-3 and has a white jacket...Its expensive but if your going to do it charge for it and do it right, I have done a few setups and it works great. I always do home runs and try to keep in mind that for every connection you open the jacket thats a place to pick up noise. I solder and heat shrink all of my joints. Longer runs use S142 and S 144 (14 awg)

Hope this helps and again I have to say this is a great site!


The 16 is around 310.00 per 1000
The 14 is around 410.00 per 1000

to follow up... i asked my local e-inspector who said this cable wasn't acceptable siting the same code sections in 725 and 310 and referred me to an email conversation he had with a UL engineer about the same cable on another job...

"You are correct, the type designation as well as a number of additional markings (manufacturer ID, UL symbol, AWG size, Temp rating if other than 60C) should be visible on the cable surface. This marking may be in
the form of surface ink printing, indent or embossed printing. A marker tape may also be used providing it is readily visible through the jacket. If these marking are not present the cable is not listed."
"I would agree. If you are unable to confirm any of the marking I previously indicated, this particular cable is not listed for any of the applications described in article 725 of the NEC."

the cables that you guys have mentioned are the right types, some look just like the old zip cord but have the markings so they are ok. thanks
