Any idea why my RCD could be tripping each night?
For over two weeks my RCD has been tripping each evening starting between 22:00 and 23:00. When I reset it it will work for anything between 5 seconds to an hour then trip again.
Sometimes a circuit breaker opens as well but not always the same one.
This continues to about 4:00 and after that the supply is fine. I have disconnected all timers, and security lights. I do not have a split CU
Help!!
