What is the primary purpose of using rigid metal conduit?

The primary purpose of using rigid metal conduit is to provide protection against mechanical damage. Rigid metal conduit is a strong and durable option for housing electrical wiring, effectively safeguarding it from physical impacts, environmental conditions, and other potential hazards. This is particularly important in industrial and commercial settings where the risk of damage to electrical systems is higher due to machinery, heavy traffic, or exposure to harsh conditions.

While electrical insulation is essential for preventing short circuits, rigid metal conduit does not directly serve this purpose; instead, it provides a path for the wires while ensuring they remain protected. The reduction of electromagnetic interference is more relevant to specific types of cable and shielding techniques rather than the conduit itself. Increasing power factor typically relates to the efficiency of electrical systems and is not directly associated with the function of conduit. Thus, the primary role of rigid metal conduit focuses on its ability to protect wired systems effectively.
