Hi Folks
My turn to ask a question! At the moment I am engaged on a contract where the above may have a significant impact! So, can anyone provide/point to any comparisons between the 2nd & 3rd editions of the standard? (and yes, I already know about many of the significant additions to the standard in Ed 3 in terms of the risk-assessment requirements - which could be quite significant in the current context, and of which I have done quite a lot over the last few years)? Any pointers would be most appreciated. Many Thanks in advance. John Allen Compliance With Experience Ltd.

As such, (virtually, again?) all of the national Wiring Rules/Regulations have the same basic documentation structures and contents along the lines of the IEC 60364 sections - but traditional national differences in wiring practices dictate that they don't always say exactly the same things. Therefore what we have are national Wiring Rules like the USA ANSI/NFPA C1 "National Electrical Code" model code of practice and the various State/City implementations into local laws and statutes - and in both the USA and European cases, backed up and explained by detailed implementation Guides prepared by the relevant official technical bodies responsible for drafting the national documents. In other words (mine at least!) "almost but not quite" European Harmonization" !! PS: As indicated above, I am sure someone in Europe can come up with a more detailed and erudite explanation of the situation.

Due to the current drawn, it sounds like the device is going to be Pluggable Type B and/or wiring terminals for final connection to supply so I would add a statement that "end installation must comply with local wiring regulations" or similar. Regards Charlie From: Peter Tarver [mailto:[email protected]] Sent: 16 May 2012 17:31 To: [email protected] Subject: Re: [PSES] Circuit breakers in Europe (Continuous vs. Non-Continuous Loads) Thank you all for your responses. I'll clarify: The current being carried is close to 16 A. Wiring is appropriately sized for this current and the length of the circuit conductors. Should the "branch circuit" overcurrent protection be rated anything other than 16A and why? Some have suggested 20 A is correct. Regards, Peter L.
