Best electrical wire for home wiring
Researched by Deal.ai's shopping agent across stores on November 2, 2026. Prices below are today's.
Top pick: Southwire Romex SIMpull 12/2 NM-B (25 ft). For general household branch circuits, 12-gauge copper is the safe default — it carries 20 amps, so it handles kitchen, laundry and garage circuits as well as ordinary outlets, and it's the wire most inspectors expect to see. Solid copper conductors, grounded, indoor-rated.
Who the others suit:
- 14/2 NM-B (15-amp circuits): lighting runs, bedroom and living-room outlets, switch legs — cheaper and easier to pull through boxes.
- Longer coils (50 ft, 250 ft, 1,000 ft): whole-room or whole-house runs; short 15 ft coils for a single outlet or fixture.
- 12/2 in longer lengths: dedicated 20-amp circuits — microwave, dishwasher, bathroom, shop outlets.
Match the gauge to the breaker: 14 AWG on 15 A, 12 AWG on 20 A, and check local code before you buy.
