how to wire a 480v to 240v 3 phase transformer?

To wire a 480V to 240V three-phase transformer, first ensure the transformer is rated for the correct voltage and phase. Connect the primary side to the 480V supply by wiring each of the three phases (L1, L2, L3) to the corresponding primary terminals. For the secondary side, connect the output terminals to your 240V load. Ensure proper grounding and follow local electrical codes for safety. Always verify connections with a multimeter before energizing the system.
