What is the corresponding specification between the rated current of the charging connector and the conductor cross-section?

For AC charging connectors: 16A corresponds to 2.5mm², 32A to 6mm², 63A to 10mm². For DC charging connectors: 80A corresponds to 16mm², 125A to 25mm², 200A to 35mm², 250A to 50mm². The final specification shall be verified with derating based on cable material and ambient temperature.
