Which of the following is a common type of electrical wiring used in residential settings?

Non-Metallic Sheathed Cable is commonly used in residential settings primarily due to its versatility and ease of installation. This type of wiring is often referred to as NM cable, and it typically consists of two or more insulated conductors and a bare ground wire all encased in a non-metallic sheath. The non-metallic covering makes it lightweight and easy to handle, which is advantageous during the installation process.

Furthermore, NM cable is approved for use in both dry and damp locations, making it suitable for a variety of residential applications. It provides good insulation and is also resistant to corrosion, which is crucial for maintaining safety standards over time. Because of these properties, it has become the standard type of wiring for electrical circuits in homes, accommodating everything from lighting fixtures to outlets.

While coaxial cables are primarily used for television and internet connections, fiber optic cables are used for high-speed data transmission and twisted pair cables are more common in telecommunications, non-metallic sheathed cables are specifically designed and accepted for residential electrical wiring, fulfilling the codes and standards required for safe electrical work in homes.
