Our take on the Southwire/Coleman Cable Non-Metallic Romex Sheathed Cable With Ground, 10/3, 200 Ft.

Southwire 10/3 NM-B is non-metallic sheathed cable with three 10-gauge copper conductors plus a ground, sold on a 200 ft spool. It is the standard wiring for 30-amp circuits: electric dryers, ranges, water heaters and subpanels. The 90°C-rated insulation and copper conductors are what electricians expect from NM-B, and Southwire is the brand most often stocked. It is stiffer and harder to pull than 12/2 or 14/2, so runs with tight bends take more effort.

Questions and answers

What is 10/3 NM-B cable used for?
It carries two hots, a neutral and a ground for 30-amp, 240-volt circuits such as electric dryers, ranges, water heaters and subpanel feeders. It is not needed for ordinary 15- or 20-amp outlet and lighting circuits.
Is 10/3 the same as 10/2?
No. 10/2 has two insulated conductors plus ground and suits 240-volt loads that need no neutral. 10/3 adds a neutral, which dryer and range circuits with 120-volt controls require.
Can it be used outdoors or underground?
No. NM-B is for dry, indoor locations such as inside walls, ceilings and crawlspaces. Wet or buried runs need UF cable or conduit.
How many amps can 10-gauge copper carry?
In typical NM-B residential use it is rated for 30 amps. The 90°C insulation rating does not raise the ampacity of the circuit.
Does the spool include a ground wire?
Yes. The cable has a bare copper ground conductor along with the three insulated 10-gauge conductors.
