Wow What a reply. Thanks for that, it really helps. I was told Rcd should be added for kitchen ring main ,cooker point, lighting and bathroom extractor. That would mean 4 Rcd's..Thanks Christine
Does there require an additional RCD for lighting circuit ( ceiling). I have had one added for ring main. Also if a cable is reduced to a cooker point and the socket moved does this also require an RCD. I DO NOT HAVE 17TH EDITION BOX.
