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

    Can you go into more detail on the EEBADS approach?

    You're making me feel old now!


    EEBADS = Earthed Equipotential Bonding and Automatic Disconnection of Supply - what ADS was referred to in years gone by (but long after the period where regs required some earthing, and perhaps a limit on the resistance between parts within an installation, but without any particular requirement for disconnection). The EEB bit got dropped from the name - possibly due to the fact that bonding doesn't really create a true equipotential zone (at least not where large fault currents are involved - Ohm's Law gets in the way), plus of course we sometimes don't even attempt to create an equipotential zone (outdoors for instance), but still have ADS.
