I am reading through IEC 61293:2020 and comparing it to what some of the Product Standards say and examples on the Web regarding the Voltage Rating that would go on a Nameplate or Label. I am really struggling with 3 phase voltage ratings. Industrial machines show this information as a table, but we want to just have a single line Rating. Our equipment is not a transformer or motor driven device, but it is powered by 3-phase. Let me know if this is correct or if there is a better way. Thank you. The Other Brian
Single Phase = 230V~ Three Phase (no neutral) = 400V 3~ or should it be 3~400V Three Phase with neutral = 230/400V 3/N~ or should it be 3/N~230/400V Is the PE conductor assumed or should it be included in the Rating, as in these examples? Three Phase without neutral and PE = 400V 3/PE~ or 3/PE~230/400V Three Phase with neutral and PE = 230/400V 3/N/PE~ or 3/N/PE~230/400V For a Three Phase device that uses the Neutral, do you always show the Phase Voltage in addition to the Line Voltage, or it is assumed? Does the "3~" go after the voltage or before? The IEC 61293:2020 shows it before, but I generally see it after. - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
