Type-NM cable, commonly known as non-metallic sheathed cable, is widely used in residential wiring due to its ease of installation and versatility. This cable is flexible and lightweight, allowing electricians to handle and maneuver it easily in various environments. It typically consists of two or more insulated conductors and a ground wire, all encased in a moisture-resistant plastic sheath. This design not only simplifies the installation process but also reduces the risk of damage compared to harder and bulkier alternatives.

The use of Type-NM cable is also favored because it can be run through walls, ceilings, and floors with minimal effort, not requiring conduit for protection, which further streamlines the wiring process in residential settings. Additionally, it is cost-effective, making it a preferred choice for both professionals and DIY enthusiasts.

Other options may provide certain benefits in specific scenarios but are generally not as easy to work with for typical residential applications as Type-NM cable.
