10/3 NM-B

IUSA Wire 10/3 NM-B Cable with Ground is heavy-duty, residential-grade building cable designed for indoor wiring when you need an extra conductor and the strength of 10 AWG. Built with three insulated copper conductors (black, red, and white) plus a bare copper ground, it’s ideal for multi-conductor branch circuits, upgrades, and applications that require heavier gauge wiring with an additional lead.

Made for clean pulls and solid terminations, IUSA Wire NM-B delivers consistent, reliable performance for new construction, remodels, and demanding residential installs.

Common uses

• Multi-conductor branch circuits requiring 10 AWG (application-dependent)
• Wiring scenarios needing an additional conductor (control/switching setups where applicable)
• Indoor residential upgrades where heavier wire is specified

Key features

• 10/3 configuration: black + red + white insulated conductors + bare ground
• Copper conductors
• For dry, indoor applications (per NM-B use guidelines)
• Built for electricians, contractors, and serious DIYers
