Neutral to earth fault on ring cuircit.

[phase]

I was IR testing ring cuircuit. One end of the cuircuit was OK but the other one showed neutral to earth fault. I checked before the continuityof the earth, line and neutral and was ok. Please any ideas of why do I get neutral to earth fault only on one of the ends.

I think we need more information, what are your readings on your continuity L-L, N-N, E-E and your IR tests? I suspect you are misinterpreting something somewhere.

L-L 0.32, N-N 0.32, E-E 0.53. I can't

recal the IR

I'm probarly missing something. It was quite late yestarday... I am going back later

You say you have ring continuity then the short should show no matter which end you are testing from. I would suspect you do not really have ring continuity on one or more of the conductors and its using another to get around the ring via a short (or shorts).

Thanks Ian. That might be the case.

Actually it cant be that simple either as any fault should still show up since both ends are still connected.

Don't forget to disconnect all loads on the circuit. Any load connected could give a low N/E reading from inside an appliance or plugtop. I agree with the above though, it wouldn't be on only one half if you had a ring.

Did you do the continuity tests then go and do the IR tests later ???

did that today on a lighting cct removed wrong neutral 2nd time around

scratched me 'ead for a while....

Hi.Just for update. It was trapped neutral in one of the single sockets. I also found one broken double socket on a spur. Now is back to normal. Thanks for your help.

Should still have given a fault reading from both ends though .

I got confused myself..I disconnected on of the sockets when i was looking for the fault and then I went to check again at CU. One of this moments...So I left it for today. :C
