Does 352.46 require bell ends and/or bushings to be installed in conduit runs traversing through underground concrete pull boxes and vaults? Is it the intent that "other enclosures" are to be construed as encompassing these pull boxes?

Typically, bell ends are used with concrete product or underground installs.connectors and bushings are ok but bell end are better.Other enclosures would be boxes with threaded hubs imo.
