Condulets max wire size

[tesi1]

If not making a junction in a condulet, such as a c-condulet,
is there a maximum wire size or fill, or is the maximum wire fill
limited only by the conduit size.

The conduit body is required to follow the same rule as boxes. For conductors larger than #6 that would be 6X and 8X the trade size of the conduit. The exception is when the conduit body contains the conductor fill information within the conduit body. Then the fill can exceed the 6X and 8X requirements.
