NEC Article 640: Audio Interconnects and Speaker Wires


Audio interconnect cables and speaker wires fall under Article 640, and so whether they can be installed in-wall or in other specific settings will depend on that article. Under NEC 640.21(C), these are in turn governed by Article 725, "Class 1, Class 2, and Class 3 Remote-Control, Signaling, and Power-Limited Circuits."

General installation of wiring, including installation inside of walls, is governed by 725.61(E), the principal features of which, for our purposes, are:

  • (1) CL2 and CL3 are always permitted;
  • (2) CL2X ("X" is a residential suffix, signifying a lower grade than plain CL2) or CL3X may be installed in raceways;
  • (3) CL2X or CL3X, if under 1/4 inch in diameter, may be installed in a 1 or 2 family residential dwelling without a raceway; if nonconcealed, it may also be installed in multifamily dwellings.

So, if a cable isn't marked CL2 or CL3, is it suitable for in-wall installation? It may be. The NEC allows cable of a higher rating to be substituted for a lower rating, and therefore, any of the following may be used: CM, CMP, CMR, CMG, CL2R, CL3R, CL2P, CL3P, PLTC. CMX also may be used where CL2X or CL3X is required.

In a plenum, 725.61(A) governs; CL2P or CL3P are required, and CMP is a permitted substitution.

A riser presents a bit different situation, governed by 725.61(B). If you're in a single or two-family dwelling, CL2, CL3, CL2X and CL3X may be used (and, of course, any of the substitutions listed above). In a commercial building or multifamily dwelling, any of those cables are permitted if they are installed in metal raceways or located in a fireproof shaft having firestops at each floor. In a commercial or multifamily building, without a raceway or shaft, if the vertical run of the cable penetrates more than one floor, CL2R or CL3R must be used (or any of these substitutes: CMR, CMP, CL2P, or CL3P).

Just what we needed to make the installation go quick and easy.  Bought the wire and speakers together so we had what we needed. Great service.

good quality, good price, good service November 5, 2015
Reviewer: Anonymous Person from Frederick, MD United States  
This cable was very expensive in the local big-box stores.  Inwall offered much better pricing and free 7 day delivery via UPS.  The cable was very easy to install in my ceiling and I can't wait to finish my remodel project so I can enjoy my new home theater!  I would definitely recommend Inwallstore.com as a reliable source.
