ROMEX GROUNDED NM-B BUILDING WIRE - 14/2G x 25 FtSouthwire 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: 14/2G - 2 insulated conductors plus bare copper equipment ground
- Length: 25 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 - White for 14 AWG (white=14, yellow=12, orange=10, black=8/6)
- Ampacity: 15A 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: 28827421
Circuit Use: 14 AWG is the standard for 15A general-lighting and general-purpose receptacle circuits in residential construction - bedrooms, living areas, hallways, and most ceiling lights. Not allowed for kitchen counter, bath, or laundry receptacle circuits, which require 20A per NEC 210.11.
Length Use Case: 25 feet handles a single device drop - one new receptacle or switch added to an existing branch, a dedicated over-stove microwave circuit, or a short fixture relocation. Leave a few feet of slack at both ends for service loops in the box and at the panel.
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.
