Which of the following is a primary function of couplings in conduit systems?

Couplings serve a crucial role in conduit systems primarily by securely connecting two lengths of conduit. This function is essential for ensuring that the conduits remain aligned and properly housed to facilitate the safe passage of electrical wiring or other materials within them. By maintaining structural integrity at the joints, couplings help to prevent failures that could lead to disruptions in the electrical system, such as loose connections or potential damage to the wires housed within the conduit.

In conduit installation, the strength and reliability of these connections can greatly affect overall performance and safety. Proper coupling ensures that the conduit system can withstand environmental stresses, mechanical impacts, and vibrations without compromising the system’s functionality. This is why they are indispensable in the design and implementation of effective conduit systems, providing both stability and security to electrical installations.
