I have a problem with one of my downstairs socket circuits. When it rains for a long period (eg in July!), the circuit sometimes (but not always) trips. It seems obvious to me that water is getting in somewhere. My thought about solving this is to find out which bit of the circuit is causing the problem and then replace it.
Seems to me that the simple way to do this is:
Turn off the circuit at the consumer unit.
Work out the layout of the circuit using a multimeter. I assume it's a ring circuit but could be spurs.
Bypass each section of the circuit in turn with cable and narrow down which one seems to be causing the problem - i.e. see which one seems to stop the rain/tripping sequence.
This could be time-consuming, but apart from that, is there anything against doing it this way?
Is there a better way? Could I measure the resistance between live and earth for each section, for example?
Thanks.
