Talk:Extra-low voltage

From Wikipedia, the free encyclopedia

[edit] Should SELV be "Separated" or "Safety" Extra Low Voltage?

IEC refer to "Safety" exclusively. See the glossary definitions here: [1]

The IEE wiring regulations (BS7671) refer to "separated". Wheatpark 11:16, 29 June 2006 (UTC)

I got the impression that at least newer IEC standards no longer claim that SELV is an acronym of any particular sequence of words. The idea that "SELV" means just "SELV" has the advantage of working in any language. Markus Kuhn 11:29, 29 June 2006 (UTC)

[edit] Intro

The entire introduction is confusing and contradicts itself. The intro states that ELV is less than 50V AC and 120V DC and then in the next paragraph says that it's less 1000V AC and 1500V DC. I can't really comprehend why an organisation would consider 1000V "low". The statements about IEC terminology 'low voltage' and common usage are just confusing. Can someone rewrite the introduction? --121.210.246.157 (talk) 21:51, 14 January 2008 (UTC)

I've added a table that more clearly displays the three official and widely used voltage-range definitions for electrical safety on all three articles on the subject. Better now? Markus Kuhn (talk) 20:17, 15 January 2008 (UTC)
