[QUOTE="Murdoch, post: 456574, member: 24445"] This is why I won't fit dual RCD boards anymore ... Are you 100% sure that all the cables are in the right neutral bars? and that with everything disconnected the IR is over 2 meg ohms? Why did you recommend rewiring the immersion - 1.5 should be good for 17A, depending on the installation method. You've done well to do a comprehensive CU change, install bonding and all this fault finding in 1 day! Sounds like you only have 5 circuits, so I would add the radial to the "good" RCD which should leave you with just the sockets - them just be very methodical with your testing. Do you have a clamp meter? Its possible that leakage from 1 circuit can affect another on the other RCD. [/QUOTE]
