I'm trying to boost a 3 phase 208V/120Y to 240 V, 3 phase. The load needs a source capacity of 30 amps.
Square D has the following site which shows transformer model numbers, and wiring diagrams:

If that link doesn't work, its the first document here:

Anyhow, the two don't agree at all. I'm getting everything from needing 0.5KVA transformers, to 1.5 KVA transformers. Some show needing a 16/32V secondary winding, some show a 24/48V secondary.
Some show the two main windings in parallel, and some in series.
Does anyone know the equations that give the relationships between input voltage, output voltage, and KVA capacity? Or can anyone help me figure out the best configuration to use?
As an example, in the configuration, I select 3 phase, 208V input, and 13.3% boost to 236 volts. It gives me a wiring diagram #7, with a 500SV46B transformer. But there isn't anything in the other document that even remotely matches that.
