Does anyone know where I can find table 48A? I am reading of its existence, but don't know where to find it.

    Would these be for mainland Europe where bathrooms may not have supplemental bonding?


    I personally would not rely on bonding alone in wet locations, in particular exterior sockets where earth mat is not practical for a user.




    Roughly harmonized across Europe, minor differences as socket-outlets are permitted in Zone 1 etc. - RCD protection gets you to 0.04 s, so OK. A slightly more cautious approach here in the UK, but there all the same.


    I don't really see an issue for "wet" or "humid" as we either apply bonding, or use RCD in the UK.



    Exterior locations are not classed as "wet" particularly in BS 7671. But your point is fair and definitely considered. RCD protection is used for outdoor socket-outlets and many items of outdoor equipment, so disconnection time is 0.04 s (Regulation 411.3.3). Larger circuits with Class I products, expect larger CPC and perhaps lower touch voltages ... and so on with that sort of thinking.
