What is the primary function of conduit fittings in electrical installations?

The primary function of conduit fittings in electrical installations is to connect and terminate conduit runs while protecting the wiring. Conduit fittings are essential components that ensure the integrity and functionality of the electrical installation. They serve several key purposes:

1. Connection Points: Conduit fittings allow for the seamless connection of different sections of conduits, enabling the electrical wiring to be routed throughout a building. This is crucial for creating a safe and organized pathway for electrical conductors.

2. Protection: One of the main roles of conduit fittings is to protect the wiring inside the conduit from physical damage, moisture, and environmental conditions. This protection helps maintain the safety and reliability of the electrical system.

3. Secure Termination: Fittings provide a secure termination point for conduit runs. This is important for ensuring that the conduits are properly sealed and that the wiring remains contained within the protective casing.

While other choices cover aspects unrelated to the primary function of conduit fittings—as they refer to aesthetics, current capacity, and insulation—they do not address the critical roles of connection and protection that are foundational to safe electrical installations.
