    Connect the primary of transformer across the phase A and B legs. If you want you can connect the primary to phase A and C legs, or even phase B to C legs of the three phase power system..

    For 208/120 volt three phase power use a 208 to 120 volt step down transformer to get you 120 volt power on the secondary, and use a 208 to 240 volt step up transformer to get 240 volt output on the secondary

    In a 208/ 120 volt 3 phase system the phase to phase voltage is 208 and the phase to neutral voltage is 120 volts
