Which type of conduit is described as Type FMC?

Type FMC refers to Flexible Metal Conduit, which is specifically designed to provide protection for electrical conductors while allowing for flexibility during installation. This type of conduit is commonly used in areas where there may be movement, vibration, or the need for changes in direction without the necessity for fittings.

Flexible Metal Conduit is made of metal and is typically utilized for both indoor and outdoor applications where exposure to moisture is not excessive. Its flexible nature allows installers to navigate around obstacles and install wiring in a way that more rigid conduit types do not allow. Additionally, the metallic construction provides grounding and can improve the overall safety and reliability of the electrical system.

In contrast, the other options pertain to different types of conduits or cable. Intermediate Metal Conduit, for instance, is heavier and more rigid compared to FMC and is used in different applications. Rigid Metal Conduit also offers protection but is not designed to flex, limiting its usage in certain scenarios. Nonmetallic-Sheathed Cable applies to a different category entirely, being an insulated cable rather than a conduit system. Thus, the correct identification of FMC as Flexible Metal Conduit distinguishes its unique qualities and applications within the framework of electrical installations.
