About the Dedicated AC line Romex 12 ga.
The Dedicated AC line Romex 12 gauge is a non-metallic sheathed (NM-B) cable primarily used for residential branch circuits requiring 20 amp capacity. It consists of two insulated copper conductors plus a bare ground wire, all enclosed in a yellow color-coded PVC jacket with a nylon covering for durability and ease of installation. The conductors are solid annealed soft copper rated for 90°C insulation temperature, with an ampacity limited to 20 amps per NEC standards. This cable is suitable for dry locations, can be fished through masonry or tile walls, and is rated for 600 volts. It is commonly used for dedicated audio or home theater AC lines to reduce electrical noise and ensure stable power delivery. The cable is compliant with ASTM, UL 83, UL 719, and NEC specifications, and is lead-free and RoHS compliant. Typical applications include dedicated circuits for high-end audio equipment, with recommendations often suggesting 12 gauge Romex for 20 amp dedicated lines with hospital-grade receptacles for optimal performance.
