Re: Big watt home theater speaker wiring
Ok, I see the FPN for 640 does include residences.
Article 400 covers flexible cords which cannot be run conceiled or attached to wall surfaces. Are any of the usual speaker wire products listed? I know ever popular "zip cord" is
but that's a flexible cord now isn't it.
Since the wiring requirements are not designated in NEC terms of Class 1, 2, 3 then how do you know what your options are for conceiled wiring? Article 725 is absolutely no help here.
As I have said many times, this is an area of the NEC that needs work.
