___ cable shall be flame-retardant, moisture-resistant, fungus-resistant, and corrosion-resistant.

___ cable shall be flame-retardant, moisture-resistant, fungus-resistant, and corrosion-resistant.

• A. MC
• B. UF
• C. NMC
• D. NMS

Answer: (C)

The correct answer refers to Non-Metallic Sheathed Cable (NMC). This type of cable is specifically designed for use in residential and light commercial applications where protection against various environmental factors is essential. NMC cable is constructed with moisture-resistant and flame-retardant materials, which help to prevent fire hazards and protect the integrity of the electrical conductors in damp conditions. Additionally, it is resistant to fungi, ensuring longevity and reliability in various environments. The corrosion-resistant properties contribute to its durability, making it suitable for use in areas where it may be exposed to harsh conditions. Other cables listed, like MC (Metal-Clad), UF (Underground Feeder), and NMS (Non-Metallic Sheathed) cable, have specific applications that may not encompass all the attributes of flame-retardance, moisture resistance, fungus resistance, and corrosion resistance collectively in the same context as NMC. NMC’s combination of these attributes is vital for ensuring safety and functionality in a wide range of residential and commercial electrical installations.
