The company I work for has ordered a large machine from the USA. Its nameplate nomenclature specifies the voltage as 460 3Ø. Our supply voltage is 600 3Ø
My question is; when ordering the transformer I believe what we require is a 600-volt to 480-volt transformer. Based on the fact that I believe 480 volts is a nominal supply voltage in the US and the 460 specified on the "nameplate" is just taking voltage drop into consideration. Am I right in my way of thinking?

I'm fairly confident that I have this right but another electrician I was speaking with figures if the nameplate specifies 460 volts then I should order the transformer to match that voltage.....and for some reason unbeknownst to me the "boss" does not want to contact the manufacturer with this question.

Appreciate any advice
