I have a piece of equipment that says it needs 460Vac, 60Hz, 3-Phase. I have a 480Vac receptacle. What, besides 20 volts differentiates these two? Is 460V and 480V somewhat synonymous? Are they one in the same as far as the motor is concerned or do I need to add a resistor to try and get it down to 460? If anyone could enlighten me it would be a great help. Thanks in advance.
