Discuss RCD trips a few minutes after lights turned on in the UK Electrical Forum area at ElectriciansForums.net

The N-E 'fault' is most likely the N-E loop of a TN-C-S installation. If you're not an electrician, with TN-C-S you have a line conductor and a neutral conductor coming in to the service head. The earth is then linked to the neutral conductor. TN-C-S stands for Terra Neutral Combined Separate as in earth/neutral combined (in the cable) and then separate (at the service head).

On the consumer side, if the installation is not fully isolated you will get a continuity reading between earth and neutral which is why you should fully isolate circuits for this kind of fault finding.
Will happen on TN-S also as neutral and earth connected at the star point of the transformer :)
 
Thanks SparkyChick ... I drew the line when I have to open up my consumer unit.
Maybe later in the year (can't believe June is coming to an end !) I will enroll in a course ,perhaps in November,and by Christmas I'll officially be qualified as an electrician to better protect my house !

btw, I had the electrician test my RCD again to make sure it is all working and it is.
Corrected that for you to be more realistic with current training requirements.
