Can anyone help with this one?
After deciding to do a periodic test on my own house (five years after moving in) I have come acrossthe following problem
The neutral of the upstairs ring has continuity (less than 1 ohm)to the neutral of both the upstairs and downstairs lighting circuits also the earths of mentioned circuits have continuity between them.
I can understand continuity between earths of upstairs and downstairs lighting circuits as cpc's are joined at two gang two way switch at bottom of stairs. But as for the rest of it i'm baffled, I have done all the obvious things like disconnecting neutrals and earths at consumer unit, removing loads (allthough no lighting transformers yet) asked my fellow electricians at work but no-one has an answer!
I have started looking under floors and finding bad things like unused live cables taped up and left under the floor and a spur taken from the ring in 1.5mm, needless to say I have rectified these and am expecting to find more such problems. Due to dodgy wiring I have found so far I will not be suprised to find interconnections between circuits somewhere, got a day off tomorrow to get to the bottom of it, so any suggestions will be greatly appreciated.
