The RCD sometimes trips (3 or 4 times in two weeks) when I switch off at a particular wall socket. My computer’s plugged in there, via a surge-protection socket. I always shut the computer down using the Windows ‘turn off’ menu, then when it’s stopped, I switch off at the wall. It’s that last action that seems to trip the RCD.
I’ve only a sketchy knowledge of RCDs, but it seems odd to me that it trips when switching off, not on. This problem began after I installed a new power supply unit in the computer, but that’s stopped running by the time I switch off at the wall. House wiring is only 4 years old.
Any thoughts please?
