Hi All
I wonder if somebody can help.
In our domestic CU one of the RCD's keeps tripping out without any of the MCB's tripping. When I reset the RCD it resets fine without any problems. All is ok for an intermittent period (could be days or hours and it trips again).
I think from the forum this is indicating a N-E fault and I need to maybe do some investigative work on each of the MCB protected circuits to try and diagnose which appliance (if any) is causing the problem. However I'm not sure if that will diagnose the issue as I've learnt the RCD shares a neutral bar with all of the affected circuits. Basically I'm not sure of the most logical way to go about doing the testing.
The RCD usually resets fine without any MCB tripping, however a couple of times one of the MCB's tripped when I reset the RCD (The circuit included some downstairs sockets/fridge/oven/alarm). The MCB reset fine though and I'm wondering if this was a red herring as only the fridge and house alarm were on at the time.
This is a new house build with full electrical certifications and only two years old. I don't want to call the electricians out for a simple fix.Any ideas please?
Thanks
