IEC 60364 Table 48A

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

    Right, where you would have a double insulated tool, which is not capable of becoming live ie made of plastic.

    Which is fine for indirect contact/fault protection, but 30mA RCDs also provide protection under direct contact situations - e.g. damage to the appliance's flex exposing the conductors.


    It's also hard to control loop impedances where long thin extension leads are in use - it doesn't take a huge amount of 0.75mm² orange flex running down the garden to get to the point where neither the MCB nor the plug fuse will reliably provide 0.4s (let alone 0.2s) disconnection.
