BS 7671 18th Edition AMD 2

John Peckham

The 18th Edition AMD 2 was signed off by the Chairman of JPEL 64 on Monday. So it can now go to the printers for publication on the 28th March.

The IET have issued a press release which gives some detail of the changes.

This can be found here. https://www.theiet.org/media/press-releases/press-releases-2022/24-january-2022-iet-and-bsi-publish-amendment-2-2022-to-bs-76712018-iet-wiring-regulations/

    I don't think Wolverhampton and the Black Country have progressed beyond the 13th edition as yet. 

    • I do wonder if the committee actually realise what the general standard of electrical installations is in this country.

    Thanks JP. Absolutely marvellous. I somehow think that AFDDs will not be appropriate for the majority of basic domestic installations, but it will be a jolly good money spinner for some company.

    Blimey, that takes me back a few decades! I am surprised to see that it is still available.

    Going to be interesting to see what they class as "higher risk residential buildings"

    I'm guessing that blocks of flats is what its alluding to. They struggle to give any data about their effectiveness in countries where they are commonly fitted, so I doubt it will be very forthcoming in this country either

    Defined in the Building Safety Bill as " high-rise residential buildings, care homes and hospitals which are 18 metres or more in height, or at least seven storeys."

    We made some changes yesterday so it looks like this may have been a result of that. Please let us know if you spot any other instances.

    The thing is; there is no regime in place to monitor the effectiveness of the things, which may mean that in the event of a follow-up post-future incident it will be impossible to prove that the incident would not have occurred had a AFDD been fitted.

    Personally, having read quite a lot of info thus far, it seems that it is nigh-on impossible to get accurate fire statistics about anything related directly to the cause in this country. Even the lazy fire brigade investigators just tick the "Caused by an electrical fault' box when all other avenues have been exhausted, and all of the easy low-hanging fruit has been picked over. They don't drill down any further to find whether or not the fault was on the DNO kit or the consumer's equipment.

    It's the same with SPDs - no one really knows how effective they really are, since nothing is being recorded about the service of these things. And what if they fail and do not prevent a surge from damaging kit? Who is to blame then? Same goes for AFDDs.
