ECN Forum Forums General Topics of the Trade General Discussion Area 480 or 460 volt secondary ?

It is hard to provide reassurance for something that doesn't exist.

They do not make 480V motors. 460V is not a nominal supply voltage, yet the NEC (US for sure and the CNEC probably) says to make all calculations using nominal voltages.

Don't you have the same problem with 575V motors on a 600V system?
