To wire a 480-volt three-phase transformer, first ensure the power is off and safety precautions are in place. Identify the primary and secondary terminals on the transformer. Connect the three-phase input lines (L1, L2, L3) to the primary terminals, ensuring correct phase alignment. For the secondary side, connect the output terminals to the load, following the appropriate voltage requirements. Use proper gauge wire and secure all connections to prevent arcing or overheating. Always consult the transformer’s wiring diagram for specific instructions.
