"Rated voltage" definition - in ETIM both as a numeric feature (EF000228) and range (EF003977)

Hello,

"Rated voltage" is a feature that has two codes whether it's a numeric feature (EF000228) or a range (EF003977). I was wondering about the definition of "Rated Voltage" and why is it sometimes a numeric feature or a range. 

I have found several definitions online, one is "The maximum voltage at which an electric component can operate for extended periods without undue degradation or safety hazard." (https://definedterm.com/rated_voltage) This would make sense for the numeric feature, is this correct? However, the fact that it can also be a range having the same description confuses me. 

A similar thing happens with "Nominal voltage". What would be the difference between the "nominal voltage" and the "rated voltage"? Is the differentiation they do in the following link correct? https://www.proz.com/kudoz/English/electronics_elect_eng/2201941-rated_voltage_nominal_voltage.html

Thanks very much,

Roberto

1) I am not an expert in this, but as far as I can see nominal and rated voltage are used alternately for the same kind of features. Also looking at other (source) translations like German and Dutch, it should be the same. 

Definitions in IEC's Elektropedia see http://www.electropedia.org/iev/iev.nsf/display?openform&ievref=482-03-31 and http://www.electropedia.org/iev/iev.nsf/display?openform&ievref=442-09-10. 

2) Numeric versus range is clear: sometimes the supported voltage is a fixed value like 220 Volt (numeric), sometimes equipment is suitable for example for 220-240 Volt, that would be a range feature then. By the way, also in a range feature you can express numeric values like 220-220 Volt.
