Our take on the 10-3 W/G NM-B Wire Orange, 250ft, 500ft, or 1000ft Coil

This is 10-gauge, 3-conductor non-metallic sheathed cable with a bare ground, the standard branch-circuit wire for dry residential wiring. It is rated 600 volts, and although the conductors are rated 90°C, the NEC limits its ampacity to the 60°C column, so it is used for 30-amp circuits such as dryers, ranges and larger appliances. The sheath is color-coded orange, which is the usual code for 10-gauge NM-B. It is lead-free and RoHS compliant and meets UL 83, UL 719 and ASTM specs, making it a direct equivalent to Romex NM-B.

Pros
  • Standard 10-3 configuration with bare ground
  • 600-volt rating and UL 719 listing
  • Lead-free and RoHS compliant
  • Solid copper conductors per ASTM B3
  • Orange sheath makes 10-gauge easy to identify
Cons
  • Ampacity limited to the 60°C column, not the 90°C conductor rating
  • Not for wet or damp locations
  • Not for exposed outdoor use
  • Stiff solid conductors are harder to pull than stranded

About the 10-3 W/G NM-B Wire Orange, 250ft, 500ft, or 1000ft Coil

This is 10-3 with ground NM-B non-metallic sheathed cable in an orange jacket, equivalent to Romex NM-B. It is used in normally dry residential installations as branch circuit wiring for outlets, lighting and other residential loads. Its applications are outlined in NEC 2008 and NEC 2011 Article 334.

It has three 10 AWG conductors plus a 10 AWG bare copper ground. Each conductor has color-coded PVC insulation with a nylon covering, and a 30 mil color-coded PVC sheath covers the assembly. The cable can be fished through masonry or tile walls where it is not exposed or subject to excessive moisture or dampness.

The cable is rated at 600 volts and a 90°C conductor temperature when dry. Under NEC 2008 and NEC 2011, its ampacity is limited to the 60°C column. It is lead free and RoHS compliant.

Questions and answers

What is 10-3 NM-B wire used for?
It is used for 30-amp branch circuits in dry residential locations, typically dryers, ranges and larger appliances. It has three insulated conductors plus a bare ground.
Can it be used outdoors or in wet areas?
No. NM-B is for normally dry installations. It may be fished through masonry or tile walls only where it is not exposed or subject to excessive moisture.
What ampacity does 10-gauge NM-B carry?
The conductors are rated 90°C, but the NEC limits NM-B ampacity to the 60°C column. For 10 AWG copper that is 30 amps.
Is it the same as Romex?
It is described as equivalent to Romex NM-B and meets UL 719 and ASTM specifications. Treat it as a standard NM-B cable.
What is included in the coil?
The coil is the cable itself: three color-coded PVC/nylon-insulated copper conductors plus a bare copper ground under a 30 mil PVC sheath. Boxes and staples are not included.
Where is the 10-3 W/G NM-B Wire Orange, 250ft, 500ft, or 1000ft Coil cheapest?
At Global Cable and Wire, for $485.00, as of our latest check.
