High Leg Delta Transformer

You could still supply 120v loads if that floating neutral was extended with the line conductor(s), it just wouldn't be a grounded neutral (nor compliant).

I almost added more wording and probably should have to that post to indicate floating to mean only tie the three transformer windings together at the wye point but not to extend or bond that point. Sort of no different than a center tap of a winding that doesn't get extended for utilization.

But yes there is 120 volts available in the system, just was trying to point out a possibility of someone maybe making a crude replacement for a real corner ground system where they only leave the source with three phase three wire ability.

Crude is the word defining that procedure. I can’t think of any logical reason to do it.

Me neither, but only reason I can think of for OP to have ~ 208 instead of ~240 unless he has some voltage drop issues or POCO is having voltage regulation issues, I usually see POCO regulation fail leaving you on high side vs low side though.
