Testa, your post was not visible to me yet when I posted last, so forgive me if I did not address any info in it.
The tap adjustments on the high side do not help me here, I believe, as the 100 percent taps give me the most I can get.
Since this is a 3 wire circuit and needs no neutral, do I care if it is wye or delta? This shop is 208/120 WYE, but I don't know about the motor.
If I seem a little short on knowledge it is because, like many electricians, I have worked at the trade for years (35) with little need to deal with transformers like this. Industrial and mill work have been a small percentage of my work which has been lots of commercial and residential stuff.
At times like these it is important to know what questions to ask, and other than this site there are really no resource people I can go to. The inside salesmen usually know only enough to order specifically and EXACTLY what YOU tell THEM. I threw a few questions at the guy at the salvage yard (tons of mill "take outs" and used mechanical and electrical equipment and the prices are RIGHT) and he looked at the logo on the side of my truck ("XXXX ELECTRIC, INC.") and said, "If you don't know, I don't know!".
The table saw in question is one of those which stops the blade instantly if you touch it (quite a finger saver) and thus has a circuit board in it which will have a power supply which uses 2 legs of the 460 to create its working voltage, so this variance in the voltage may actually be quite important.
I am always amazed the havoc customers can cause when they do not consult an electrician before ordering a piece of equipment.
