    Be honest. You don't want to do that with a ground bus. You want to do it with a lay-in lug because you forgot to pick up a ground bar that morning. Or maybe you want to use just a green screw.
    Actually true, I have did it when finishing up late night on a panel swap and wanted power on that night. Just gotta get back and fix it in morning before inspection.

    I did this exact thing during a panel change once. Made the old panel a j-box and mounted the new panel beside it. Split-bolt all the grounds together along with a #10 I ran to the new panel. Inspector failed it. I complained to his boss who said it was fine and voided the violation.

    ETA: It was a huge split bolt

    ETA2: Yes, I got away with murder.

    Inspector was correct, unless you can show that the split bolt was listed for that many and size of conductors. Doubtful IME.

    I wasn't smart enough at the time to know you were only allowed two wires in a split bolt.

    That is excusable, the inspector’s boss over riding the inspector is not. Boss was an idiot IMO.

    I'm talking about your basic wire nut, typically for a service upgrade where the EGCs are not long enough to reach the new panel's EGC bus.

    I have also paired circuits, combining two neutrals to a single white pigtail, effectively making MWBCs that split into two circuits before leaving the panel.

    I had done that in the past as well until they came up with the handle tie/2-pole CB rule for MWBC's.
