421.1.201

lyledunn
I note that this U.K. only regulation is now included in the new Irish standard IS10101:2020 as sub-clause 421.2. I am not sure if this is the U.K. committee persuading the Irish committee of the merits of non-combustible consumer units or if the U.K. committee has persuaded CENELEC such that the regulation will be included in future amendments to HD60364-4-42. Anyone know?

By the way, unlike the U.K. regulation the Irish equivalent does not seem to allow for the alternative of placing a plastic unit in an enclosure constructed of non-combustible material.

    I can't answer the direct question, but I note that a recent review of domestic electrical fire origins in Sweden puts CUs high in the list, leaving me wondering how long before someone thinks of doing something about it. For places with combustible surroundings the principle of fire-safe CUs strikes me as very sensible, and I've several times pointed to the UK's change.  

    Some things haven't got better over time, like the move from diazed fuses in brass/steel/porcelain housings, over to plastic MCBs in light plastic boxes without backs, mounted on plasterboard or worse. Perhaps the "TT countries" would be more bothered than others about making a change. Or the countries where CUs are as tall as a person (well - several rows of din-rails).
