Our take on the Wirenco 12/2 NM-B, Non-Metallic, Sheathed Cable, Residential Indoor Wire, Used for Wiring Swiches, Outlets and other Loads with Dry Applications (50Ft Cut)

Wirenco 12/2 NM-B is non-metallic sheathed cable for dry indoor branch circuits: outlets, switches and lighting on 20-amp circuits. It has two 12 AWG insulated conductors plus a 10 AWG ground, a 30-mil PVC sheath and a 600-volt rating, and it meets UL 83, UL 719 and ASTM specs. The 12-gauge copper makes it stiffer and harder to pull than 14/2, so it suits dedicated 20-amp runs rather than quick lighting taps. It is a commodity item, so it competes with Southwire and other NM-B brands on sheath quality and how cleanly it pulls, not on features.

Each conductor has color-coded PVC insulation with a nylon covering that meets the thickness required for Type THHN. A 30 mil color-coded PVC sheath is applied over the completed assembly. The cable is lead free and RoHS compliant.

The cable is rated at 600 volts. Its conductors are rated at 90°C dry, but ampacity is limited to 60°C under NEC 2008 and NEC 2011. Applications are outlined in NEC 2008 and NEC 2011 Article 334.

Questions and answers

Can I use this for a 20-amp outlet circuit?
Yes. Two 12 AWG conductors plus a 10 AWG ground suit a 20-amp, 120-volt branch circuit. The ampacity is limited to the 60°C column, which caps it at 20 amps.
Is it rated for outdoor or wet locations?
No. NM-B is for normally dry indoor installations. It can be fished through masonry or tile walls where it stays dry, but not where exposed to moisture.
What is the difference between 12/2 and 14/2?
12/2 has thicker copper and supports 20-amp circuits; 14/2 is limited to 15 amps. 12/2 is stiffer and harder to pull, so use 14/2 for lighting-only runs.
Does it include a ground wire?
Yes. The cable has two insulated 12 AWG conductors and one bare 10 AWG ground.
Can it be used in conduit?
NM-B is a sheathed cable meant to run without conduit in dry walls and ceilings. Where code requires conduit, individual THHN conductors are the usual choice.
Is it lead-free?
Yes. The cable is lead-free and RoHS compliant.
