12-2/2 W/GRND NM-B Romex

Allowable Ampacity for 12-2/2 W/GRND NM-B Romex: 20 Amps


Romex Type NM-B Copper Building Wire is commonly applied in residential building wiring as a branch circuit for switches and outlets. It can also be used for various building purposes, both inside and outside (the temperature should not exceed 90 °C). NM-B electrical wire can be used in air voids in tile walls. The voltage rating of the cable is 600 volts. The electrical wire is easily installed because it is specifically designed for easier pulling. 

Also Known As:

12-2/2 NM-B Wire, 12-2/2 NM-B Cable, 12-2/2 Non-Metallic Sheathed Cable, 12-2/2 Non-Metallic Sheathed Wire, 12-2/2 Romex Wire, 12-2/2 W Grnd NM-B Romex


  • ASTM B-3 and B-8
  • UL Standard 83
  • UL Standard 719
  • Federal Specification A-A-59544
  • National Electrical Code, NFPA 70. 2011 Edition



The cable has 2/2 conductors with a bare ground wire. The conductors are made of soft bare annealed copper.


The cable has a polyvinyl chloride (PVC) insulation, making it perfect for harsh conditions. 


PVC jacket comes in yellow, orange, white, and black colors.

Romex Type 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 2011 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.

    Romex Type 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 Type NM-B 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.
