Which type of conduit is known as Type MC?

Type MC conduit refers to Metal-Clad Cable. It is a type of wiring that consists of conductors enclosed in a flexible metal sheath. This sheath provides both protection against physical damage and a grounding path, making it suitable for various applications, especially in environments where some degree of flexibility is required, such as in industrial and commercial settings.

This type of conduit is valued for its durability and versatility, allowing it to be used in locations that may not be suitable for rigid conduits. The metal sheath also offers added safety against electrical stress, which is essential in ensuring compliance with the National Electrical Code (NEC) standards for electrical installations.

In contrast, other types mentioned, such as plastic conduit, rigid metal conduit, and intermediate metal conduit, serve different purposes and have distinct construction and application characteristics that do not align with the designation of Type MC.
