Southwire Romex Type NM-B nonmetallic-sheathed cable in a cut length, ready for indoor branch-circuit wiring. Solid copper conductors with 90C THHN/THWN-2 thermoplastic insulation inside a flame-retardant, moisture-resistant PVC jacket - the standard wiring method for residential dry-location branch circuits per NEC Article 334.

• Gauge / Conductors: 12/2G - 2 insulated conductors plus bare copper equipment ground
• Length: 50 Ft cut piece, individually boxed for shelf service
• Insulation: 600V THHN/THWN-2 rated 90C; ampacity used at the 60C column per NEC 334.80
• Jacket: color-coded NEMA convention - Yellow for 12 AWG (white=14, yellow=12, orange=10, black=8/6)
• Ampacity: 20A maximum overcurrent protection on 120V circuits
• Use in dry interior locations only - inside walls, ceilings, and accessible attic spaces of one- and two-family dwellings
• Manufacturer Part No: 28828222

Circuit Use: 12 AWG handles the 20A small-appliance branch circuits the NEC requires for kitchen counter receptacles, bathroom receptacles, laundry receptacles, and garage outlets. Also used for individual 20A 120V circuits feeding microwaves, dishwashers, garbage disposals, and dedicated workshop outlets.

Length Use Case: 50 feet covers a typical room-scale run - a new branch circuit extended from the panel to a single room, a small basement workshop subfeed, or a garage outlet add. Allow extra length for routing around joists, plates, and through bored studs rather than running tight.

NM-B vs UF vs MC: Type NM-B is for indoor dry-location use only. Switch to UF cable for direct burial or damp/wet locations, and to MC (metal-clad) cable for installations exposed to physical damage or where local code requires an armored sheath. Do not use NM-B in conduit fills, embedded in concrete, or anywhere exposed to moisture.

Tip: Pull the cable, do not push it - kinks in NM-B are permanent and stress the insulation at the bend. Strip the outer jacket with the built-in rip cord (pull the inner cord 6-8 inches back from the cut, then split the jacket lengthwise) rather than scoring with a knife, which risks nicking the conductor insulation underneath.
