Lets say you have a 208v single phase source and are using a buck/boost transformer to change to a 240v single phase load. Would upping the voltage reduce the current draw from the source? Looking at basics ohms law it seems that way, but I'm not sure if that's right

No I meant from the source, I think I got it figured out it would only change the amperage between the transformer and the load where the voltage is changed

The amperage in the circuit is the sum of the transformer losses and the driven load.

The amperage in the driven load is dependent on voltage supplied.

If you reduce the supplied voltage by bucking it down, then it reduces the total circuit current. Kirchoff's law.

Assuming that the power draw remains constant,
then upping the voltage will reduce the current.
