This type of electrical cable, commonly available at a large home improvement retailer, is a non-metallic sheathed cable used for residential wiring. The designation “14 3” indicates a 14-gauge wire containing three conductors plus a ground. An example of its use would be wiring a standard 15-amp circuit for outlets and lighting.
This cable’s prevalence is due to its suitability for many common household electrical circuits. Its availability at a major retailer provides convenient access for both professionals and homeowners undertaking electrical projects. Historically, this type of wiring replaced older methods, offering improved safety and ease of installation when adhering to electrical codes.
