@ieales - I disagree. I did testing with a double-run of 14awg romex (that's 2x14awg which makes an 11awg total). The result was just not as good as a standard 12awg or 10awg romex. The smaller 14awg just cannot respond to on-demand current as well as the larger awg romex.
High quality in-wall UL-C2 rated 10-gauge A/C wiring ?
I am looking to re-wire my listening area front-wall with a dedicated A/C circuit using 10-gauge UL-C2 rated in-wall wiring. I know Audience makes a high-quality one however I didn't want to pay $26/foot. I would need ~60-ft. I've already purchased two high-quality A/C receptacles and wanted to do 10-gauge to them from a dedicated breaker.
Anyone have any experience with this or know of other mfg's of 10-gauge A/C UL-C2 wiring ?
Thanks !

About 4 months ago I ran 2 runs (40' each) of the Audience Hidden Treasure in-wall AC cable to my system. I paid $18 per foot for it and used 2 Furutech GTX-D NCF (R) outlets. Audience is located in San Diego, Ca. and I live in Los Angeles, Ca. Big step up from the standard #12 wire I had replaced. Very expensive but if you don't have a long run it's worth considering. |
@ron17 Had you hired a reputable licensed electrician for the install he would have told you it does not meet the National Electrical Code for branch circuit wiring. CL2, Class 2 cable. CL2: This is a cable jacket fire resistance rating defined in Article 725 of the National Electric Code. It stands for "Class 2 Remote-Control, Signaling, and Power-Limited Circuits" cable, which indicates that the cable is suitable for in-wall installation and use for certain low-voltage applications. Examples of Class 2 circuits include burglar alarm cabling, intercom wiring, and speaker wire. The jacket is designed to protect against voltage surges of up to 150 volts.https://www.cablewholesale.com/support/technical_articles/confusing_cable_terms.php The jacket is designed to protect against voltage surges of up to 150 volts.The branch circuit wiring in your home has a 600V rating. NEC Article 725 https://www.ecmweb.com/cee-news-archive/classification-circuits-under-article-725 https://www.thecableco.com/power-ac-in-wall-power-cord-bulk.html
This cable meets the NEC. (Verify with your local AHJ for your area. Note the red outer jacket. Not required by the NEC to be orange in color because the conductors are #10awg.) Color coding of NM cable is a NEMA manufacturer thing. *** I am not recommending the cable one way or the other. *** Note: The maximum branch circuit breaker size is 20 amp for 2 or more 15 amp outlets or for a 20 amp outlet/s Jim . |
@jea48 - interesting read, but the problem I had did not relate to ground loop buzz / voltage inducement. I believe now it had to do with the voltage in the tiny 14awg wire being restricted by the high dielectric constant on the insulation (something I have definitely found on small gauge wires). On a larger 10/12awg conductor, there is less percentage of voltage restriction with more area/mass of conductor. My result of 2x14awg romex was weak bass/midbass punch. A single 12awg gave much better impact/sound. |
