- What is 8/2 NM-B cable used for?
- It feeds 40 A, 240 V loads that need two hots and a ground, such as electric ranges, cooktops and subpanel feeders. It is for dry indoor locations only.

- No. It has two insulated conductors plus a bare ground. Appliances that need a neutral, such as some ranges with 120 V controls, require 8/3 instead.
- Can 8/2 NM-B be used outdoors or underground?
- No. NM-B is rated for dry, protected indoor spaces. Use UF cable for underground or wet locations.

- The cable is rated 40 A, so it pairs with a 40 A breaker for typical branch circuits. Confirm the load and local code before sizing.
