- What can I wire with 10-2 NM-B?
- It is for 30-amp, 240-volt circuits in dry indoor locations, such as an electric dryer, water heater or range hood. It has two insulated conductors plus a bare ground.
- Can I use it outdoors or underground?
- No. NM-B is rated for dry indoor locations only. For wet, outdoor or buried runs, use UF cable or conduit-rated wire instead.
- Can it go inside conduit?
- NM-B is not meant to be pulled through conduit as a wiring method. It is designed for running through studs, joists and attic or crawl spaces.
- Does it include a ground wire?
- Yes. It has a bare copper ground conductor along with the two insulated conductors. The ground is not insulated, so keep it clear of live terminals at boxes.
- Is 10-gauge overkill for a normal outlet?
- Yes for most 15- and 20-amp circuits, where 14- and 12-gauge are standard. Buy 10-2 only when the circuit is rated 30 amps.
