    Ammendment 2 AFDD BS7671

    AFDD are manditory from the 28th of March on fixed final circuits using current carrying equipment not exeeding 32a People opinions on this. Also if a house doesn't have an afdd what would you code this as on a condition report ? Basically every Circuit would have to be an rcbo afdd at £130 a...

    Considering adding SPD and AFDD to my 17th Edition compliant CU

    Am I on the right lines, I ask? I've just recently moved into this house which is nicely equipped with a large 15 circuit CU unit with a split load x2 RCD's but first, I think an EICR would be a good idea to give a starting point reference at least, before any work is done I'm considering having...

    FuseBox AFDD Combined RCBO

    Just seen that FuseBox are offering AFDD Combined RCBO but cost on-line is £115+VAT so not exactly affordable yet! https://www.expertelectrical.co.uk/fusebox-afdd-combined-rcbo

    UK RCD/ combined afdd breakers

    Hi can someone tell me whether I need to record the trip times on x1 or x5 on this combined device,as I'm getting trip times of 44/45 ms x1 and sometimes a lot lower ie 29 ms.This device is the sole means of isolation. Cheers

    Best AFDD board as of Nov 2020

    So if a customer really really wanted a board with AFDDs in... what's the best RCBO/AFDD solution out there right now ? I can only find Crabtree and Wylex, but I guess there must be others now too ?

    UK SPD and AFDD practical experience

    HI I am looking at a job where the CU needs an upgrade as its plastic and has no spare ways for the circuit I will be installing. Looking at giving customer options so will be quoting for metal CU, integral SPD and looking at combined RCBOs and AFDDs for each circuit, looking at the spec for...

    So AFDD then for all Landlords???

    I was just thinking if NAPIT are coding no RCD on lighting, to comply with the new LL law/S.I. as C2 then presumably we would also have to say absence of AFDD is likewise C2? And how about SPD as well. This surely can't be right, making regs retrospective.

    How does the overvoltage protection from AFDD works?

    So i know the arc detection is made by a MCU. The overload and overcurrent by a magnetic coil and bimetal. But what about Overvoltage ? I only know it works for >270V.

    AFDD requirement and smoke alarms 18th ed

    Am I correct in thinking under the 18th edition for a new build property an AFDD is compulsory or is this not the case if risk assessed? I am still yet to complete my 18th ed. Also for new build properties is it still ok to hard wire smoke and fire detectors off lighting circuits under 18th...

    AFDDs are a massive fraud

    Derailed another thread with AFDDs, so I am starting this one. I will simply say that UK RCDs and MCBs provide arc fault protection as is. UL not only knows that, but extensively researched UK power systems in an effort to emulate the very same concept 40 years. One the simply fact (growing...

    AFDD Covering Arse

    Hi guys just looking to see what everyone else does when not installing any AFDDs when the customer isn't interested in them (can't really blame them) I currently just put a note on the certificate saying that client was advised but refused them. If anyone has any information about what the...

    BS 7671 Regulation 532.6 AFDD

    Hi all, I know there have probably been posts on this already, but I can’t find it. The regulation above says “Where specified, Arc Fault Detection Devices shall be installed....” Where is it specified? I’ve been looking in the book, on line and on here. Even speaking to NICEIC and board...

    AFDD, Building Regs and Insurance

    Hello all. New here so i may get flamed if this is covered somewhere else, but I've been scouring google for ages without any conclusions. I'm of the understanding now that AFDDs need to be installed in certain locations, sleeping accommodation being the one I'm interested in as it constitutes a...

    Why does AFDD protection need to be per circuit?

    Hi again! Why does AFDD protection where provided need to be installed per circuit instead one AFDD covering several circuits, like for example RCDs in domestic split load CUs? Is there a technical reason or is it another manufacturers money making myth!? Thanks.

    Demonstration of an AFDD by wylex

    Saw this on youtube part of the GSH channel. Probably the best video to demonstrate an AFDD in use I have seen as of yet, It is a Wylex one and no doubt pricey, i could see the time in a few years where the AFDD and rcbo will all be incorporated into 2 modules and each circuit protected by one...
