@ Wtshymanski: Change [1] claims: "not true enough to be worth saying here" about the fact that three phase nominal voltages are by a factor of √3 larger than the corresponding single phase. I would say, that the difference between three phase voltages (phase to phase) and single phase (phase to neutral) is always sqrt(3), as this is a fact from geometry [2]. Basically the cosine of 30° is half of √3, and this ratio does not change whatever voltage level you choose. Therefore the relation between three phase voltage and corresponing single phase voltage is always √3 and obviously this is worth saying here at it is not known to everyone. "for instance, 480 V systems, 600 V systems" - I am not sure about these voltages but it seems (see IEC_60038) that 277 V / 480 V and 347 V / 600 V are the corresponding 1ph vs 3ph voltage pairs, thus the statement is perfectly right.

"Confirmed by looking at Aqualectric meter" is something like original research? Not a major editor so I'm not gonna actually go in and correct it, but like. Ellenor2000 ( talk) 14:57, 9 October 2023 (UTC)
Please help me with... Hello!
I came across the data in Wikipedia, today, for which I believe is wrong. It's about electricity in Slovenia. There is a table that says it is 230V, but in fact it is 220v. It's here:
/info/en/?search=Mains_electricity_by_country
I don't know how to edit it, so I decided to just write here. Couldn't find any other possibility.
Thanks in advance for correcting that data.
Best regards, Alja Žehelj (from Slovenia) 89.233.115.214 ( talk) 17:28, 14 March 2024 (UTC)
In the table section for Belgium, the three-phase table cell says 230/400 V. Although I can not verify, doesn't Belgium have similar systems like norway having both 230 V (three-phase without neutral) and 400 V (230 V/400 V star with neutral)? Although I don't think belgium commonly uses the IT grid, unlike norway. Now for japan, where is the source for the 415 V three-phase (either delta, or 240 V/415 V star) that is supposedly in use in Japan?
I'm new to the talk section, so I will do my best to follow guidelines on discussion boards. Additionally, I rarely edit wikipedia articles so I am not going to make edits yet.

Dear anonymous editor: Please stop reverting and find sources. The ones I have found did not agree with you:
These sources might be wrong, but you need to provide better ones in order to introduce these island into the table. Викидим ( talk) 20:35, 2 July 2024 (UTC)
