Can a earth fault on a lighting circuit effect another circuit , this being ring main , only two circuits in flat, After changing a light fitting i came across an earth fault on the lighting circuit , I thought i had sorted earth fault out but the other circuit in the flat started tripping , when the lighting circuit cpc is removed from earth bar , nothing trips both circuits power up. With lighting cpc in earth bar ring main trips, not on rcbos.
Well, if IR really is 200 Ohms, then the installation is leaking over 1 amp - which may well be lethal. Have you tried breaking the sections down to find out why so low (and as above a few continuity tests
What was the lighting circuit fault - what was the repair
