Re: [PSES] 230V 3-phase in Europe

Hi John, I believe IT system in Norway is still in use since they declared national difference to new hazard based EN 62368-1 standard with below text: Norway: After the 3rd paragraph the following is added: Due to the IT power system used, capacitors are required to be rated for the

You don’t need to go to Wikipedia. Apparently, the laws of Australia are permitted to contradict the laws of mathematics. Australian Prime Minister Malcolm Turnbull has asked software companies to provide a backdoor into their operating systems for the Australian government to use. Security

“Somehow”, I think that will not happen – the “Scientific community “ would not permit it! To those who think otherwise I say “beware of what you wish for because it may then come true” (to the UK members - think “JC” and Venezuela, maybe?) John E Allen W. London, UK From: Doug Powell

You are quite right; the household supply is 230/400V. I suspect that the product description is wrong. 133/230 V isn’t used anywhere in the world, I think. With best wishes DESIGN IT IN! OOO – Own Opinions Only www.jmwa.demon.co.uk J M Woodgate and Associates

Re: [PSES] RED DoC and LVD

I do not think that the spirit has any legal value here. My experiences in these kind of cases is that judges read the letter and not the spirit. If the letter gives no clear legal solution, the spirit may help. But the letter is quite clear here. The only unclear part is the use of

[PSES] 230V 3-phase in Europe

Greetings. Sorry if this is a stupid question (I’ve asked more than I’m allowed, I’m sure), but in Europe, is there 230 volt 3-phase (230 volt line to line)? I thought 230 volt single phase was derived from 380V 3-phase (230V from Line to Neutral). I see a 230V 3-phase saw with a CE marking

I don’t think that is helpful. Agreed that the ‘Whereas’ are not legalistically part of the Directive, that doesn’t mean that they can be disregarded. They embody the reasoning underlying the Directive. In English legal idiom, they contain the ‘spirit’ of the Directive, while the Directive

The numbered Whereas clauses are NOT part of the directive. The actual text of the directive starts after the stipulation HAVE ADOPTED THIS DIRECTIVE: , just after consideration clause number (75) and just before article 1: The text before this phrase therefore cannot be part of it,
