What are metal conduit couplings primarily designed for?

Metal conduit couplings are essential components in electrical installations, specifically engineered to connect two pieces of conduit securely. This connection enables the continuous routing of electrical wiring through the conduit system, ensuring that the electrical circuit remains intact and provides protection from physical damage and environmental factors.

The design of couplings allows for flexibility and ease of installation, enabling electricians to extend or modify conduit runs as necessary while maintaining safety and compliance with electrical codes. By providing a reliable connection point, couplings play a fundamental role in the organization and efficiency of electrical wiring systems, thereby enhancing the overall effectiveness of the installation.
