    What do you mean by "bond the enclosure"? The incoming conduit will bond the metal box so nothing else needs doing to the box.

    it is probably somewhat lower by the time it gets to the bucket.

    I am not sure what you are asking.

    I do not see a code violation.

    I am not a huge fan of the "someone might do something in the future" reasoning.

    What do the contract plans and specifications state?

    I think it would be appropriate for the 600V side to not be grounded, or to remove the fuse in the grounded conductor.

    I do not believe there is a problem tapping off the load side of a MPCB to a branch CB that feeds the control xfmr. He can certainly tap off the line side of it just to be sure.

    I am not sure I like the idea of having a MCB. Even if it is well coordinated, there is still some chance that a downstream fault will trip the main before the feeder CB trips.
