Trying to wrap my head around a possible issue.

How long can the screws for mounting/changing equipment in an MCC bucket be? I figured that the spacing requirements would be a NEMA standard or published by the manufacturers but this seems to be some obscure information I can't find anywhere.

Thinking of the "blind reaching" problem. There clearly has to be some kind of standard established for this but I can't find it anywhere and it may be simply that I haven't come up with the right terminology to find the answer. NEMA ICS clearly implies that there needs to be a 1" bus clearance including fasteners but I can't find anything on the fasteners themselves.

Hello My name is Soman, nice to meet you
