    So you're asking about a single 15a receptacle on a 30a breaker?

    To me, that's worse than the same load shared by several receptacles on a 30a circuit.

    No, between several to two dozen 15/20 amp receptacles on a 30 amp circuit.

    I've got another theory.

    Because the screw terminals are not rated for the larger wire, and, scabbing on a piece of #12 to a #10 to make it happen would be a code violation.

    Are the terminals on a 15a device rated for #10?

    You don't create one rule to prevent the violation of another- at least I believe that is the intent of the NEC.

    Meaning the code would not limit receptacles to 20amp circuits because someone might violate 240.4 (D)

    Then my original answer stands.
