When pulled directly through without splices, what is the function of a conduit body in a conduit system?

A conduit body serves multiple functions within a conduit system, and one of its primary purposes is to provide access for maintenance. By creating an accessible point in the conduit run, it allows electricians or technicians to inspect, troubleshoot, and perform maintenance on the conductors within the system without needing to disassemble the entire conduit installation. This accessibility is crucial for ensuring the reliability and safety of the electrical system, particularly in systems that may require periodic checks or modifications.

The other options, while relevant to the overall functionality of conduit systems, do not fully capture the specific role of a conduit body when there are no splices in the conductors. Protecting conductors and supporting them are important functions in various contexts but are typically maintained by the conduit itself rather than the conduit body. Similarly, connecting multiple raceways is another significant role but pertains more to the nature of junction boxes or certain types of connectors rather than the specific contributions of a conduit body.
