Hi,
I've had one RCD trip yesterday and 2 tonight. Of course, this also coincides with my alarm battery being flat, so everytime it trips, the alarm goes off. As you would expect, it's only tripping at night! I'll be off in search of a new battery tomorrow.
Everything has been fine and dandy for years, and this has only occured since I changed an MCB out on the RCD protected side of the CU from a 16 to a 20 AMP. This my be coincidence but could a lose wire or similar be causing this?
The first trip occured when I switched the dish washer on at the issolation switch. After that trip, I switched it on and off several times and ran it without any issues.
Tonight, the next trip occured when I switched the tumble dryer off at the issolation switch. I then flicked the switch back on in panic. I reset the RCD. About 10 minutes later, the RCD tripped again so before resetting it, I issolated all devices in that area (tumble dryer, dish washer and washing machine).
In daylight I'm goign to check that all the MCB's and wires are tight in the CU. Other than that, can anyone advice on anything else I can check or if I should get a pro in?
Thanks.
