50 Feet 14/2 Type NM-B Copper Cable - Reliable Residential Wiring

Our review of the 50 ft 14/2 Type NM-B Copper cable finds it best suited for homeowners and electricians needing a straightforward, code-compliant solution for branch circuits. This cable's single biggest selling point is its combination of recognized standards compliance and everyday practicality: it is listed to UL and ASTM standards and intended for typical dry residential installations, making it a dependable choice for sockets, switches, and general lighting circuits. For anyone doing interior wiring where temperatures stay below 90C and ampacity follows 60C conductor limits, this cable delivers solid value.

Key Features

• UL and ASTM listed: Meets UL Standard 719 and UL 83 plus ASTM B-3 and B-8, providing confidence in conductor construction and materials.
• Code compliant: Conforms to the National Electrical Code, NFPA 70, so it is suitable for standard residential branch-circuit work.
• 600 V rating: Rated for up to 600 volts, offering ample voltage capacity for household circuits and typical fixtures.
• Nonmetallic sheathing: NM-B jacket in white allows discreet runs in visible and hidden dry locations and blends with common wall colors.
• 50 ft length: The 50 ft spool is practical for single-room runs or patching existing wiring without excess waste.
• RoHS/REACH compliant: Manufactured to modern environmental standards for restricted substances.

Who It's For

This cable is ideal for homeowners doing DIY electrical projects, remodelers, and electricians handling typical indoor wiring tasks like supplying outlets, switches, and light fixtures in dry areas. It is especially useful when a moderate, pre-cut length such as 50 ft matches the run between junction points without requiring multiple splices.

Those who need cable for wet locations, outdoor use, or high-temperature environments should look elsewhere; NM-B is intended for standard dry building interiors and its ampacity is tied to 60C conductor limits despite a 90C jacket rating. For commercial runs requiring armored or conduit-protected wiring, choose a product specified for that environment.

Pros & Cons

Pros

• Good build quality with copper conductors that customers note as reliable and consistent for residential wiring.
• Clear compliance with UL, ASTM, and NEC standards gives installers confidence when meeting code requirements.
• Practical 50 ft length reduces waste for many single-room jobs while the white NM-B jacket is unobtrusive in finished spaces.

Cons

• Limited to dry locations and subject to ampacity limits of 60C conductors, so it is not appropriate for damp or high-temperature installations.

Frequently Asked Questions

Can this cable be used outdoors?
No. This NM-B cable is intended for dry interior locations; for outdoor or wet locations choose cable rated for those environments.

What temperature limits apply?
The jacket is rated to 90C, but ampacity must be applied based on 60C conductor limits per the National Electrical Code.

Is this cable suitable for kitchen and bathroom circuits?
Yes for interior dry locations; however, circuits near sinks or wet areas must follow local code and placement rules to avoid exposure to moisture.
