    Now on a Delta you would tie an H1 on one tr to an H2 on the next and so on untill all the points are tied in series to form the triangle or delta.

    You can wire either of these primary conections to get a wye 120/208 or 240/ 477 four wire secondary depending on the secondary coils of the tubs.

    You can also wire the WYE or Delta banks to deliver delta 240 or 480 depending if the internal coils are wired in series for 480 or parallel for 240 (A to C and B to D for 240 - or B to C for 480)
    Maybe I should have stated that I was speaking of Wye primary and Delta on the secondary side, every closed Delta bank that I have ever built with Wye primary on the topside, the floating neutral will be tied across the 3 pots on the high side all together meaning all on H1 or all on H2,hopefully this helps clear up my original question.
