Which of the following is an example of a raceway?

A raceway is a conduit system used to protect and route electrical wiring. It can come in various forms and materials, designed to serve different purposes within electrical installations.

Rigid Metal Conduit (RMC), for example, is a type of raceway that provides excellent physical protection for electrical conductors. It is robust and can be easily installed in both indoor and outdoor environments, making it ideal for applications that require durability and resistance to environmental factors.

Liquidtight Flexible Metal Conduit (LFMC) is another type of raceway that allows for flexibility in installations while offering protection from moisture and physical damage. It is often used when a rigid conduit is impractical due to the change in direction or in wet locations.

Additionally, AC cable, while not a traditional raceway like RMC or LFMC, often includes integrated raceway features (like armor or sheathing) that serve the purpose of protecting conductors inside.

Since all these options serve different functions related to wiring protection and installation, they collectively represent different aspects of raceway systems. Thus, the inclusion of AC cable alongside LFMC and RMC highlights the versatility and breadth of raceway functionalities in electrical applications.
