Hi Brian, Below is an extract from table F.2 of IEC 62368-1. Maybe it helps.

By the voltages, It's Europe, but it's best to be clear. In principle, the Product Standard is definitive, so what does it say? I have never seen the PE mentioned in this context, and it's best to keep the information as simple as is sufficient. I doubt that the order of the voltage and supply type statements is critical. Does the product need a neutral? If not, don't mention it; use 400V 3~ unless the Product Standard requires something different.

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.
