Is 10/2 the right wire for a 30-amp circuit?

Yes. 10-gauge copper is rated for 30 amps, which covers water heaters, dryers, and similar 240V loads. Check your local code and the appliance's nameplate before you buy.

Can I use this outdoors or underground?

No. NMW/G is for dry indoor locations. Outdoors or buried, you need UF cable or conduit-rated wire.

Does it include a ground wire?

Yes. It has two insulated conductors plus a bare copper ground. The ground is not insulated, so keep it bonded at both ends.

Is 25 feet enough for my run?

Measure the path, not the straight-line distance, and add slack at both ends. If the run is close to 25 feet, buy a longer coil.

Is solid wire harder to work with than stranded?

It is stiffer and harder to pull through tight bends, but it terminates cleanly on screws and breakers. For long or conduit runs, stranded is easier.

Our take on the Southwire Romex 25 ft 10/2 Solid Orange NMW/G Electrical Wire

Southwire Romex 10/2 is 25 feet of solid copper, two-conductor cable with a bare ground, sheathed in orange PVC. The orange jacket marks it as 10-gauge, which is what 30-amp circuits call for: water heaters, dryers, and some EV chargers. It is UL listed and sold by the foot in a coil, so you buy only the run you need.
