Tripping RCD caused by damp outdoor sockets
Why it happens here
Homes near the water meadows have garden and outbuilding sockets that take on moisture during wet spells. Water bridges the contacts and trips the RCD as soon as the circuit is used.
Our approach
We isolate the affected circuit, test with an insulation resistance tester, and replace any socket showing corrosion. We also reseal or reposition outdoor fittings to reduce repeat problems.
