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

    The IET should investigate actual touch voltages during a fault for various scenerios.   

     




    What makes you think there's no information available? Commentary on the IET Wiring Regulations, but far more informative were presentations given by David Latimer entitled Earthing and bonding - what does it do?  presented as part of the IET Tutorial Workshop on Earthing and Bonding Techniques for Electrical Installations (presented at various locations in London, Manchester, Glasgow and Belfast, between March 2005 and September 2007). One seminar digest that contains his paper and slides is ISBN 078 0 863 418372, and he runs through the possible touch voltages (and how to estimate them with and without bonding), and how they relate to IEC 60479 as they stood at the time.


    Worth also remembering that, since 1992, it's no longer the IET alone who are responsible for BS 7671. It's joint IET / BSI and the standard is published by consensus. The organisations represented are listed in the front of BS 7671.
