Since last night (high winds and rain), one of the RCDs has been tripping with a loud bang every so often, perhaps 8 times last night. I switched it back on this morning, it tripped a couple more times in the morning and 4+ times throughout the afternoon. Sometimes it'll go 10-30minutes sometimes a few hours.
There are 6/7 MCB on the RCD, the one that goes off at the same time is the downstairs ring circuit.
The sockets have been tested, seemingly OK. There are a few sockets upstairs on the downstairs ring.
I have unplugged everything from sockets except oven/dishwasher/freezer where they are hardwired but I turned them off at their switches - it still tripped.
An electrician came tonight, could not find the source of the problem and suggested I keep a track of what's happening when it goes off.. I was hopeful about the condensation they found in the box below the outdoor floodlight, they taped up the wires i think.
Since the electrician left at 6pm I've had the heating on for over 3 hours, it's 21:30 now. About 7pm I used the oven and hob to make dinner, the freezer and fridge and running, as well as running a quick wash on the dishwasher.
At 21:30 it's tripped again, Louise is on our bed using the laptop and I'm on the PC in the lounge - both on a different RCD (new parts of house), unaffected by the trip. It's not windy out and it's not raining.
I already feel like I've discount any appliance i'm aware of including the boiler, we have underfloor heating in the utility and downstairs bathroom but they have not worked properly for a few years and have been left switched off.
Sorry to ask, but I feel stuck - any ideas?
