What aspect of residential wiring does non-metallic sheathed cable (NM) primarily address?

• A. High-voltage applications
• B. Data transmission
• C. Low-voltage residential applications
• D. Industrial circuit systems

Answer: (C)

Non-metallic sheathed cable (NM) is specifically designed for residential wiring, particularly in low-voltage applications. This type of cable is composed of insulated conductors wrapped in a protective plastic sheath, which makes it ideal for residential environments where the electrical demands do not require the added robustness of metal sheathing. NM cable is commonly used in various residential circuits for lighting and receptacles, making it a standard choice for home construction and renovations. The design of NM cable allows it to be easily installed within walls, ceilings, and other structures, providing flexibility while maintaining safety standards. It is rated for use in typical household voltages, which typically do not exceed 600 volts, and this distinguishes it from other types of wiring that may be designed for more specialized applications such as high-voltage or industrial use. Moreover, NM cable contributes to simpler, cost-effective installations for standard electrical systems in homes, hence making it the most suitable option for low-voltage residential applications.
