Tripping RCD caused by damp outside sockets
Why it happens here
Westwood takes coastal rain and wind, and outside sockets on older properties were often fitted without a proper weatherproof enclosure. Water gets into the back box and trips the RCD every time the circuit is used.
Our approach
We isolate the outside circuit, test insulation resistance and replace the socket with a sealed weatherproof unit. We also check the cable gland and the breaker before restoring power, so the fault does not return next storm season.
