[QUOTE="Ardet R, post: 467931, member: 30040"] I think ProDave has probably covered it, you need to check the test results of the electricians who installed it (I am sure you have some available!) and see where they have been made up rather than measured. As an initial check on your installation for the lighting, without the power on check continuity from the top of the 63A MCB to the outgoing line terminals of each RCBO and check you have not got a terminal caught on the core insulation. For the socket circuit I would tend to do a continuity test (again with the power off) on the outgoing Line and Neutral terminals of the second power circuit to see what current it might be drawing (I=V/R). Then check line neutral continuity for each lighting feed to the first point, as nothing is working on the lights it must be the feeds, but overall I would expect you have had a rogue electrician to install the house wiring, so it will need a lot of checking to ensure safety. As far as I can tell you have this arrangement at present. Though I am just guessing at the purpose of the circuits) [ATTACH]9454._xfImport[/ATTACH] [/QUOTE]
