Run residential 30-amp branch circuits with this 25-foot length of Southwire 10/3 NM-B non-metallic sheathed cable. The assembly carries three insulated 10 AWG solid copper conductors (black, red, white) plus a bare copper equipment ground inside a sunlight-resistant PVC outer jacket. Rated 600V and listed to UL Standard 719, this is the cable to pull when the job calls for a 30A 240V circuit like an electric dryer, cooktop, or subpanel feeder.

• 10 AWG (3 insulated conductors plus bare copper equipment ground)
• Solid annealed copper conductors per ASTM B3
• THHN/THWN-style PVC insulation on the current-carrying conductors
• Color-coded jackets: black, red, white, plus bare ground
• 30-amp ampacity at 60 deg C per NEC 334.80 / 240.4(D)
• 600V rated, sunlight-resistant PVC outer jacket
• For interior wiring in dry locations only (not for direct burial or outdoor use - see UF-B for those)
• Not approved for use inside conduit or raceway (NEC 334.15)
• UL Listed per Standard 719 for residential branch circuits per NEC Article 334
• Length: 25 Ft

Common Uses: 30-amp 240V branch circuits including electric clothes dryers (4-wire NEMA 14-30 receptacle), built-in electric cooktops and ovens, 240V well pumps, and small subpanel feeders inside the home.

Install Tip: Staple within 12 inches of the box and every 4-1/2 feet thereafter (NEC 334.30). When the cable passes through a stud bore less than 1-1/4 inch from the stud face, protect it with a 1/16 inch steel nail plate to prevent drywall screws from piercing the jacket.
