Southwire Company has announced the introduction of a new four conductor non-metallic (NM-B) cable that will provide labor savings to contractors while meeting new code requirements. The Type NM-B 2/2/conductor cable, marketed by Southwire under the ROMEX®brand name, is designed for running two circuits to bedrooms in areas that require the new Arc Fault Circuit Interrupter (AFCI).
The new ROMEX® Extra Circuit NM-B, available in 14 and 12 gauge, contains four conductors-black, white, red, and white with red stripe- and a bare copper grounding conductor.
Nonmetallic-Sheathed Cable. 600 Volt. Copper Conductors. Color-Coded Jacket. Four Conductor Available With Two Neutrals. SIMpull® Jacket Designed for Easier Pulling.
Southwire® Romex® Brand SIMpull® NM-B (nonmetallic-sheathed) cable may be used for both exposed and concealed work in normally dry locations at temperatures not to exceed 90°C (with ampacity limited to that for 60°C conductors) as specified in the National Electrical Code. NM-B cable is primarily used in residential wiring as branch circuits for outlets, switches, and other loads. NM-B cable may be run in air voids of masonry block or tile walls where such walls are not wet or damp locations. Voltage rating for NM-B cable is 600 volts.
Southwire Romex® Brand SIMpull® NM-B cable is manufactured as 2, 3, or 4 conductor cable, with a bare ground wire. Copper conductors are annealed (soft)copper. Stranded conductors are compressed stranded. Conductor insulation is 90°C-rated polyvinyl chloride (PVC), nylon jacketed. Romex® Brand SIMpull® NM-B cable is designed for easier pulling, resulting in easier installation. The cable jacket is color-coded for quick size identification; White – 14 AWG, Yellow – 12 AWG, Orange – 10 AWG, and Black – 8 AWG and 6 AWG.
