A ______, with an integral bushed opening shall be used at the end of a conduit or other raceway that terminates underground where the conductors or cables emerge as a direct burial wiring method.

The correct answer indicates that either a terminal fitting or a bushing is suitable for use at the end of a conduit or other raceway that terminates underground when conductors or cables emerge for direct burial.

A terminal fitting is designed to provide a secure connection for conductors as they transition from a raceway to the surrounding environment, ensuring that the conductors are safely connected without risk of exposure or damage. It often comes with integrated features that help maintain the integrity of the connection and provide strain relief.

A bushing, on the other hand, serves as a protective component that helps prevent abrasion and damage to the conductors as they exit the conduit. The integral bushed opening is essential for minimizing the risk of injury to the cables or conductors, as well as providing a smooth transition from the raceway to the surrounding soil, maintaining the code requirements for grounding and protection.

In essence, both terminal fittings and bushings fulfill important roles in ensuring safe and compliant installation practices at the point of transition from raceways to direct burial applications. This adaptability in using either option reflects the flexibility provided in wiring methods and materials to meet specific installation scenarios and standards.
