Can you put 480 volts on motor wired for 230 volts?

It depends on the device, if for instances the machine is a pc, laptop mobile phone charger or anything that has a modern switch mode power supply built into it then you can use it on anything between 110 and 240, it will auto select, i don't recommend attaching a machine that is rated at 240v to a 460v supply, you will need to contact the manufacture to determine operating parameter's.
