Nonmetallic-Sheathed Cable includes which types?

Nonmetallic-Sheathed Cable encompasses a variety of cable types that are utilized for residential and certain commercial wiring applications. The correct answer, which includes NM (Nonmetallic Sheathed Cable), NMC (Nonmetallic Sheathed Cable for Marine Applications), and NMS (Nonmetallic Service Cable), correctly identifies the various formats under the nonmetallic sheathed category recognized by the National Electrical Code (NEC).

NM is commonly used for wiring inside buildings, providing insulation and protection for the conductors. NMC is specifically designed for use where there's a likelihood of exposure to moisture, typically found in marine environments. NMS is utilized where additional protection from moisture and other environmental conditions is necessary.

These cables are characterized by their flexible nonmetallic outer sheath, which provides excellent resistance to various environmental factors, helping to ensure safety and durability in electrical installations. Understanding these distinctions is vital for professionals in the field to select the appropriate cable type based on application and environmental conditions.
