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

The function of a conduit body in a conduit system is primarily to allow access for maintenance. Conduit bodies are designed as junction points where conductors can be accessed, which is crucial during installation, troubleshooting, or repairs. They can help facilitate connections between different runs of conduit or provide a location to change directions of the wiring, making it easier to manage and maintain the electrical systems.

While conduit bodies may also provide some level of protection for conductors and help support them in certain situations, their key purpose is to ensure that access is available when maintenance is required. This makes it easier for electricians to work on the system without needing to dismantle significant portions of the conduit setup.
