AFDDs AMD 2

John Peckham
In response to the suggestion of separate threads for individual changes to the 18th I thought I would start this one for AFDDs.


So what are the forum members views on the new requirement for AFDDs?


What is the safety case for the change? E.g impact on public safety, fires etc.Evidence?


What is the impact on the installation industry? How easy to fit, cost advantages disadvantages etc?


Will you feedback to the BSI on the changes and what will you say?

    AFDDs

    Looking at changes in the new wiring regulations for Ireland  The NSAI published the 5th Edition National Rules for Electrical Installations, IS 10101:2020 on 6 March 2020. This replaced the 4th Edition, ET 101:2008.


    The say on AFDDs Clause 421.7

    Arc Fault Detection Devices (AFDDs) will now be recommended for circuits installed in locations with particular risk, such as;


    in premises with sleeping accommodation;

    in locations with risks of fire due to the nature of processed or stored materials, i.e. BE2 locations, (e.g. barns, wood-working shops, stores of combustible materials);

    in locations with combustible constructional materials, (example = wooden buildings);

    in fire propagating structures

    in locations with endangering of irreplaceable goods

    Question:

    In the UK. As most of the New domestic  Dwellings and social Housing going up now are wooden construction on a concrete base with a single brick wall on the outside, will these installations need AFDD?


    The now called Irish Regulations, also require Fireproof cables to be used in wellings.

    Also, frown on metal comsumer units being used, you can read for yourself.
