BS 7671 18th Edition AMD 2

Thanks for the info and link.

From the press release:

Significant changes include:

• a new requirement for Arc Fault Detection Devices (AFDDs) in some AC final circuits for installations in some types of higher risk residential buildings;

• the requirement for the fire safety design of buildings to be documented where specific conditions of external influence exist, such as protected escape routes and locations with risk of fire;

• method for determining the requirement to provide overvoltage protection;

• changes to identification, labels and notices, such as for consumer units, affecting how safety information is provided to the user of the electrical installation;

• a chapter on Prosumer’s Low Voltage Electrical Installations, in a new part, Part 8.

as well as:

Further changes are included throughout all parts of BS 7671, including the incorporation of Amendment 1:2020 to BS 7671:2018 as part of the main document.

Indeed thanks for the link JP.

The bit that caught my eye was

"Members of the committee responsible for the technical content of BS 7671, JPEL/64, are not permitted to release any further information before the publication date"

I do not recall anything like that for previous AMDs - is it a new thing or did I just not realise it was the case last time? 

I  presume there will be the usual rash of wiring matters type articles to cover anything revolutionary or contentious in the days after publication.

It's always been the case. I've been involved with activities of JPEL/64 for almost 20 years, and it's always been the same, as with other BSI Committees.

Similarly, it's possible to communicate about the content of a draft only after the draft has been published for public comment, but not before.

Thanks for clarifying  - it seems fair enough, and thinking back we used to do that with the 3GPP stuff, so there was more or less a united front about when a new release came out (*), but it was more than a decade ago, and I  have no idea if it is still true  -it just read a  bit oddly seeing it like that in a press release - especially as that very  release seems to 'trailer' the contents.

Mike.

(*) though of course those companies who sent delegates to the meeting still had an in-house advantage as they provided the content and the research that supported it.
