- What circuits is 10/2 NM-B used for?
- It is standard for 30-amp, 240-volt circuits such as electric dryers, water heaters, and ranges, and for some 30-amp subpanels. It has two insulated conductors plus a bare ground, so it cannot serve a circuit that needs a separate neutral.
- Can this cable be buried or used outdoors?
- No. NM-B is rated for dry, protected indoor locations. Direct burial needs UF cable, and wet or outdoor runs need a wet-location-rated wiring method.
- How many amps can 10 AWG carry?
- In typical NM-B residential use, 10 AWG copper is limited to 30 amps. In conduit or free air the allowable ampacity is higher, but the cable's 60°C rating caps it at 30 amps.
- Is 10/2 the same as 10/3?
- No. 10/2 has two insulated conductors plus ground; 10/3 has three insulated conductors plus ground. Use 10/3 when the circuit needs a neutral, such as a dryer with 120-volt controls.
- How much cable does a 1000-foot reel cover?
- It gives 1000 feet of continuous run, enough for several 30-amp circuits or one long feeder. Plan for waste at each end and check voltage drop on long runs.
- Does it come with connectors or a box?
- No. The reel is cable only; staples, connectors, and boxes are bought separately. Check local code for the clamps and supports your installation needs.
