What is required anywhere a cable or cable assembly enters a panel or enclosure?

In any electrical installation where a cable or cable assembly enters a panel or enclosure, a connector is essential. Connectors serve as the means to secure and facilitate a proper electrical connection between the cable and the internal components of the panel. This not only ensures a reliable electrical flow but also helps prevent damage to the cable and potential hazards arising from loose or exposed connections.

Connectors can also help maintain the integrity of enclosures by providing strain relief, which protects the cables from mechanical stress. Moreover, they often play a role in ensuring that the connection is adequately insulated, thereby reducing the risk of short circuits or electrical failures.

The importance of having a connector is pivotal in meeting safety standards and regulations, ensuring that installations are up to code and function correctly, thereby enhancing overall system reliability.
