What are the benefits of using a coupling in conduit systems?

Using a coupling in conduit systems is essential because it serves the primary function of securely connecting two lengths of conduit together. This connection ensures that the electrical wiring within the conduit remains protected and that the system maintains its integrity. Couplings help facilitate the installation and maintenance of conduit runs by allowing for easy joining and alignment of different sections of conduit, which is crucial for electrical safety and compliance with regulations.

The secure connection provided by a coupling also helps prevent potential issues such as pull-out, which can occur if conduits are not properly joined. This ensures that the conduit system remains robust and can withstand physical stresses. Additionally, couplings can accommodate slight variations in alignment between conduit sections, making them a versatile choice in installations.

The other concepts don't align with the primary purpose of couplings. For example, while reducing total conduit length or eliminating the need for conduit entirely may seem like potential benefits, these are not functions of couplings. They are specifically designed to connect, not replace or eliminate conduit runs or their components. Similarly, while conduit boxes are important in electrical systems, they serve a different purpose.
