Shower with no RCD or supplementary bonding

MrJack96

I have been round to a relatives flat and seen he has an old Wylex board with MCBs. His bathroom has no supplementary bonding from what I can see and no RCD protection for his electric shower. how potentially dangerous is this? I know the circuits are fairly short and can see main bonding in place Can only really think if the R2 values are low enough touch voltages should end up being kept low?

    Thank you Andy. 

     

    so when it comes to the 50/ia rule this is between say the water pipe and the CPC of the shower what else should be considered is it simultaneously accessible parts? 

    when you say faults not involving the PE system do you mean water ingress that could end up in voltage tacking across it?
