What is a major function of electrical fittings?

The major function of electrical fittings is to connect and support wiring systems. This role is critical in ensuring that the electrical circuits are safely and securely linked, allowing electricity to flow through the infrastructure without interruption. Electrical fittings include a variety of components, such as connectors, junction boxes, and conduits, which play integral roles in maintaining the integrity of the electrical system. By providing physical support for wires and connections, electrical fittings help to prevent accidental disconnections and reduce the risk of damage due to environmental factors or mechanical stress.

While other choices mention aspects related to safety and efficiency, they do not capture the primary role of electrical fittings in terms of connectivity and structural support. For example, protecting against short circuits is a safety feature influenced by the overall design and installation practices rather than the sole purpose of electrical fittings. Similarly, while energy efficiency may be a desired outcome of a properly installed system, it is not a direct function of the fittings themselves. Lastly, while metallic conduits serve specific functions, they fall under the broader category of electrical fittings rather than defining their main purpose.
