: Hi:
: I ordered the wrong voltage air compressor and was wondering of what are the problems that we can face. The power supply at the shop is three phase 208V and the air compressor motor is three phase 230V. they would have to charge me 25% for restocking fees plus I have to pay shipping twice for return and the new one.
: Can I use the wrong voltage air compressor? Is it possible that the motor may burn out due to wrong amperage draw?
: Thank you for the reply.
: Moe
No problem.
Standard motor voltages are 115, 230, 460, 575. North American manufactured motors are designed to accept voltages of + or - 15% of rated voltage.
Your motor should work on as little as 195.5 volts.
Many refrigeration compressors are rated at 230 volts, with a minimum voltage of 197 shown on the name plate.
It is standard practice to operate 230 volt 3 phase motors on 208 volts.
