Wirenco 12/3 NM-B Indoor Residential Wire (50Ft Cut)

Applications:

The non-metallic sheathed NM-B cable is primarily designed for use in residential wiring typically found in dry installations. It serves as a branch circuit for lighting, outlets, and various residential loads. Details regarding these applications can be found in the NEC 2008 and NEC 2011 under Article 334. The NM-B cable has a voltage rating of 600 volts and is capable of withstanding conductor temperatures up to 90°C when dry; however, according to the NEC standards, its ampacity is restricted to a maximum of 60°C. This cable can be installed through masonry or tiled walls, provided it is neither exposed to excessive moisture nor damp conditions. Notably, NM-B cables are free of lead and comply with RoHS directives. It is equivalent to Romex NM-B.

Standards:

The NM-B cable meets or surpasses all relevant ASTM specifications, including those detailed in UL Standard 83, which governs thermoplastic insulated wires and cables, and UL Standard 719, which pertains to non-metallic cables. Additionally, it adheres to the Federal Specification A-A-59544 and complies with NEC requirements.
