[QUOTE="binky, post: 510390, member: 490"] So what happened to 'nuisance tripping' that precludes the use of a single RCD ? As far as I can remember singe rcd main switch went out of favour around 20 years ago. So if I was inspecting an installation over 20 years old, then a single RCD could be deemed 'acceptable' in my opinion, but if someone has stuck an RCD in more recently, for instance, to meet the introduction of RCD protection for all ccts under the 18th edition, then surely this is bad practice?
