i had a phone call off my mate today he had done cu change ,dual rcd as per 17th,he said alls fine until i turn on the landing light (2 way switch) and both the rcds keep tripping,turns out he had put up lights and down lights on different rcds as recomended,turns out when the council wired the house 10 years ago(now private)they had borrowed the neutral for the landing light,so he put both circuits on the one rcd and it worked no problem.he has now told the customer she needs a neutral running from down light circuit to landing light and she has agreed to the work.these new boards are gonna cause some headaches.lol
