VEVOR NM-B Electrical Wire Cable

Product Overview

The VEVOR NM-B wire is a high-quality electrical cable designed primarily for residential wiring applications. It is suitable for use in branch circuits for outlets, switches, and various other electrical loads. The cable is engineered for both exposed and concealed work in dry locations, providing a reliable solution for home improvement and electrical infrastructure projects.

Construction and Materials

The NM-B cable is built to rigorous standards to ensure safety and durability. The conductors are made of bare copper, adhering to ASTM B3 standards. Depending on the specific gauge, the conductors are either solid or Class B compressed stranded per ASTM B8. Each phase and neutral conductor is insulated with Polyvinyl Chloride (PVC) and protected by a Nylon Sheath. The outer jacket is also constructed from durable Polyvinyl Chloride (PVC). The color coding for the conductors is standardized: 2-conductor cables feature black and white wires, while 3-conductor cables include black, red, and white wires. A solid soft-drawn bare copper wire is included for grounding purposes.

Applications and Safety

NM-B cable is rated for a maximum voltage of 600 volts. It is intended for use in dry locations and can be installed in air voids of masonry block or tile walls, provided these areas are not wet or damp. While the individual conductor insulation is rated for 90 degrees Celsius, the ampacity of the cable is limited to that of 60 degrees Celsius conductors as specified by the National Electrical Code (NEC). It is important to note that these conductors are not listed as THHN and must not be installed apart from the complete NM-B cable assembly. Always ensure that the installation complies with local electrical codes and regulations. Users must read the manual carefully before beginning any electrical work to prevent injury and ensure the correct method of use.

Installation Guidelines

When routing conductors inside panelboards and boxes, the conductors are considered part of the complete Type NM-B cable assembly even when the outer jacket is removed for termination. Ensure all connections are secure and performed by qualified personnel if necessary. The product appearance may vary slightly based on the specific model received. Always keep this manual for future reference regarding maintenance and safety checks.
