should know this, maybe have asked this here before even, but i never use it and i'm not too sure, sooo...
i saw 16/2 speaker cable [clear zip cord with the copper wire visible thru the clear insulation], the UL sticker at the bottom of the reel on this job site says Power Limited Circuit Cable...
this cant be put in walls, right? 725.71? refers to listed labeled cable to protect against fire spread... labeled on the wire... it was run thruout this new house under construction for speakers... so what can you use for speaker cables? i have seen some zip cords with tiny writing that nobody can read. is that it?

They make speaker wire that has a twisted pair in a jacket like romex. I've also seen it in 2 pair for volume controls. Home Depot in my area sells it, but I get it from a buddy of mine who does low volt only. I've seen it in 16, 14, and 12 awg stranded.

it should be one of these: CM, CL2, or CL3, and should be visible on the cable, right? 725.71, 310.11

I have been using 16-2 shielded. Some stuff they use factories shielding keeps noise out. 8 cents a foot.

Zip-cord of any size is not rated for in-wall use regardless of use, correct?

Most seriously, 10/3-G NM-B cable is four #10s for stereo speakers. [Inspector may have a cow, but it's low loss and cheap! ..and not a Code violation.]

Pigtail smaller stranded stuff on the ends. Splice in 1-gang box with 1-hole plate {or drill for 5-way binding posts} as needed.

i find the use of that kind of speaker wire all the time in bc canada and it has been installed very recently when i ask the home owner about it they say that a new company is installing it as prewire and and after an inspector has left who can compete with this as i need apermit to install any wire for sound, satellite, data, etc i also find it recently installed in office pa systems by so called sound contractors found in the yellow pages in vancouver bc they require ft-6 ouch

Cindy,
I don't know about the cable you have, but General Cable makes one the fits that description under their Carol Brand. See it here: http://www.generalcable.com/North_America/NorthAMCat.html and do a search for C1558 or C1458

Although this is a zipcord, be advised, this stuff is NOT cheap. It is General's answer to Monster Cable. It even has vanilla embeded in the jacket to make it smell better than the monster cable.
