IP2X inside enclosures

wallywombat
Generally these days everything live(*) inside an enclosure like a CU (accessible only with a tool yada yada) seems to be IP2X - e.g. recessed terminal screws on MCBs, busbar covers, etc.


Is there anything in BS 7671 which enforces this? Or product standards like BS EN 61439? Or is it just down to good practice by the manufacturers?


(*), well, line anyway.

    Are you trying to say that the busbars must be insulated


    I'm not saying anything, or expressing any opinion. I merely observed that some forms of enclosure (such as CUs) often seem to have IP2X-ish protection, and was wondering aloud whether this is due to any regulations, or whether it's at the whim of the manufacturer.
