Can anybody please help? i have a property which i rent out the letting agency which manage property just had a annual inspection done on the electrics. it has come back with no continuity on upstairs ring main on all three cables the property was rewired about a year ago before i purchased it. I have just just checked the fuseboard i disconnected one of the lives off the fuse thinking half the upstairs power points would go dead so i could record which ones went dead then do the same with the other live. so i could then check to see if any of the power points only had a single cable going to it on the seperate circuits then i planned to connect these with 2.5mm twin/earth to make the ring. But when i disconnectd the 1 live all of the upstairs p/points went dead. i found one power point in one of the bedrooms with only one cable going to it. so why has somebody taken 2 cables off the fuse with one not doing anything? any ideas please? and can i run a cable back from the power point with one cable going to it back to the fuseboard to complete the ring?
