Last few days/hours to comment on Amendment 2, BS7671 before the shutters close

mapj1
Just a reminder the deadline for comments on the latest draft for  comment is fast approaching - this Friday the 11th in fact. (Though it is not clear if that is midday or midnight, so probably best to log in and out again before the end of Thursday..)


If you wish to comment and have not yet done so you need to create an account on the BSI website

Click on login/register on the RHS of the BSI welcome page  and  give them an email you can read without needing to change machine, as you need to click a verify link they send you.

Once logged in  search for "BS 7671:2018" oddly searching for BS 7671 without the space between BS and 7671:2018 does not find it...

There are 4 links as the thing is a bit of a monster. PDFs of each part can be downloaded for perusal, but to finally comment you need the on-screen viewer (the Read Draft and comment button)

This is not quick so allow plenty of time.

    I can’t be bothered to comment on the AFDD proposal, it is such a stupid idea that I sort of assume it won’t go through, but who knows?


    It’s not really my problem if it does go through, but there is going to be some mighty ###### off potential customers.

    Reading through some of the comments on AFDDs is interesting. They're not all completely opposed (although probably 95-ish percent are). A number ask for a higher limit than 32A - some suggest limiting the requirement to new builds or new circuits or that lighting circuits be included.


    One comment about the wider than intended scope of the regulation got me thinking ... where will I find an AFDD for my 8V transformer driven door bell circuit? (After all, it is a single-phase AC final circuit supplying fixed current-using equipment with a rated current not exceeding 32A...)

    Rather than jump through all of THEIR hoops to comment, why not just send them links to Mr Savery's (and others) videos on youtube - His presentation is faultless!

    I have given up trying to access it, never mind find it.

    They don't make it easy to comment do they? I wonder why?

    Mike, thank you for the reminder. FWIW, I have suggested a much simpler determination as to whether SPD is required or not.

    Protection against transient overvoltages shall be provided where the consequence caused by the overvoltage could result in:

    (i) serious injury to, or loss of, human life; or

    (ii) any other intolerable risk of loss.



    Note: In order to determine whether a risk is intolerable, a discussion will need to take place between the designer, installer and any other relevant parties, such as the installation owner and/or end-user. The following factors should be taken into consideration:

    (i) the magnitude of financial loss including the loss of data or equipment;

    (ii) the chance of a transient overvoltage occurring; and

    (iii) the cost of providing protection.


    It really is quite simple: cost of protection < cost of loss x chance of loss. Anywhere!

    Does this make it any easier? https://standardsdevelopment.bsigroup.com/projects/2019-02917#/section

    Door bell transformers are bombproof Andy.

    I think I'll just adopt much greater use of the Deviations box. It's much cheaper for both me and the customer, and BSI will no doubt ignore the comments submitted thus far because they'll have had their arms twisted by the manufacturers eager to get their rubbish to market.

    You reach a point in your life whereby experience tells you that if something sounds too good to be true, then it most likely is, especially if it is reassuring expensive but next to useless.

    would it trip if a Sparky came calling?
