What is the purpose of conduit fittings?

The purpose of conduit fittings is primarily to connect and secure sections of conduit. These fittings play a critical role in ensuring that conduit runs are properly assembled and that their alignment remains intact throughout their use. By securely fastening different sections of conduit together, these fittings help maintain the integrity of the wiring system and protect the wires from physical damage and environmental factors.

In additional context, while electrical connections can be made within conduit's ends, this is not the primary function of the fittings themselves. The insulation of electrical wiring and monitoring electrical load pertains to other components in the electrical system and does not relate to the design and functionality of conduit fittings. Thus, the selection confirms that their main role is structural rather than electrical.
