Hi All I have a regular old style Hager CU with a single RCD. Roughly half the circuits are RCD protected and the other half are not. I'd like to put my cooker circuit onto an RCBO and was wondering what an acceptable method would be for connecting the mains, cooker and RCBO neutrals. I obviously can't connect them on the RCD neutral bus bar, and not can they go on the nonRCD neutral bus bar, so they will have to be connected separately. Would a wago-style connector block be OK? Would the connector block need to be attached to the CU with a proper mounting? Are there any regulations about this? Anyone ever done this before?
