Southwire Romex NM-B non-metallic sheathed cable in 12/2 and 14/2 with ground, in 15, 25 and 50 ft lengths. Gauge follows the breaker: 14/2 on a 15 amp circuit, 12/2 on a 20 amp circuit, and undersizing it is a fire rather than a shortcut. NM-B is rated for dry interior locations only — not burial, not wet locations, and not exposed runs where it can take damage. Short coils like these suit repairs, device additions and small runs rather than wiring a whole house.
