Hi all I was wondering if anyone could shed some light on an issue I cant seem to get my head around, say we had a metal socket earthed and a water pipe with main bonding, I touched the both of them in fault condition on socket (live touching metal box) now i understand the bonding puts the pipe at the same earth potential so no difference between the box and the pipe so no current will flow and I wont receive a shock.
Now this confused me as when we have parallel earth paths in say a socket circuit via metal trunking and conduit, this reduces our zs reading as fault current flows down the paralle paths.
How are both these actions not the same surely me touching both the earthed box and bonded conductor creates a parallel earth path?
Any help appreciated the theory of this has been annoying me for days.
