Bob:
IMHO, I would ask the following questions regarding the lugs:
Did they come with the transformer? Probably not.
What documentation do you have, or could you obtain from the trans mfg regarding a "spec' on the lugs?
Does mfg want 'full lug to landing' contact, with ALL six (6) mounting holes utilized??
Also, looking at the full size pics, I may have a concern with the 'C' phase (secondary) buss and the bonding conductor. Please note that I am going by what I "see" in the pic; it looks like it's touching the buss???
