Hi Phil, IEC 60038 defines the standard nominal voltages, but that doesn’t necessarily reflect the reality on the ground. IEC operates the “World plugs” web page that gives the national standard voltages and plugs used by country: https://iectest.iec.ch/world-plugs, however, they only list single-phase voltages. There is a similar reference at https://www.worldstandards.eu/electricity/plug-voltage-by-country/.
I have not found an online reference for three-phase voltages, Doug Nix [email protected] +1 (519) 729-5704 > On May 6, 2023, at 05:09, Agar, Philip (Leonardo, UK) > <[email protected]> wrote: > > Please could someone advise me on what standard, if any, might compel a > manufacturer to rate the operating voltage of their equipment to at least > cover the utility supply tolerance of the region in which it is being sold? > For example, a DoC for an IT item sold in the UK claims conformance with the > requirements of LVD Directive 2014/35/EU and EN62368-1:2014+A11:2017 but it > is not clear to me that the specified voltage rating of 100 - 240 Vac > necessarily covers UK utility supply tolerance of up to 253 Vac, or even in > much of the EU at 243.8 Vac. > > Thanks, > Phil Agar > EMC Compliance > > > > > - > ---------------------------------------------------------------- > This message is from the IEEE Product Safety Engineering Society emc-pstc > discussion list.
