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

As Long as you do not have more than a 10% voltage variance from nameplate values at the machine you will be fine.
As long as you keep it within that magic number there no noticeable loss in life expectancy or torque reduction.
Also it's better to be a little high rather than low.If you ask me 5% high is perfect since you will be shipping this machine out and you have no control over the customers supply voltage.It's all relative to the machines new home or in this case homes.
cheers
