how to wire a 3 phase buck boost transformer?

To wire a 3-phase buck-boost transformer, first identify the primary and secondary windings. Connect the primary side to the 3-phase supply, ensuring correct phase alignment. For a buck configuration, connect the secondary winding in parallel with the load, while for a boost configuration, connect it in series. Ensure proper grounding and use appropriate fuses or circuit breakers for protection. Always follow local electrical codes and safety standards during installation.
