Hi Guys Rcd main switch on board so do you need sup bonding as all circuits are Rcd protected? I know realy need to upgrade board act customer reluctant. Cheers Haj
 
If all circuits in bath/shower room are 30ma rcd protected,required disconnection times are met AND you have a continuity reading of less than 1667 ohms between extraneous conductive parts and conductive parts in the bath/shower room,you dont need supplementary bonding.
