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: 10/2G - 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 - Orange for 10 AWG (white=14, yellow=12, orange=10, black=8/6)
• Ampacity: 30A maximum overcurrent protection on 240V circuits
• Use in dry interior locations only - inside walls, ceilings, and accessible attic spaces of one- and two-family dwellings
• Manufacturer Part No: 28829022

Circuit Use: 10/2G with ground is used for 30A 240V single-pole circuits - electric water heaters, baseboard heat zones, and other 240V loads where a neutral is not needed. The two insulated conductors carry the two hot legs; the bare copper wire is equipment ground only, not a current-carrying neutral.

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.
