Is my earth trip ultra sensitive faulty? RCD breakers never trips. Why do all circuits cause earth trips with very low load ? Light switches can trip.

Is my earth trip faulty?
The crcuit breaker never trips.
Why do all circuits cause earth trips with low load ? PC monitor ok but not 45" led tv & 30A circuit cooker circuit & up/down sockets same.
Earth reset rejects to latch but eventually latch on any circuit. can trip again if any small addition (mob. torch charger, small led light)?
We had water leak from wc above kitchen & just a half pint of water each time & I assumed cause but now seems coincidence? I checked sockets & pulled out live & earths - no change.
2 old freebie full fridges without power for 3 days! No micro, aircook,kettle,tv,pc (now black screen with "sector" problem same day? etc.
Can't use my PC & struggling with old laptop without my passwords or email, Google etc.
PLEASE HELP.
THANKS in anticipation.

Below if you plz. read will add further info...........................

NO PC. The reason I asked is it could be due to cumulative leakage. You said it is putting something additional on that then trips it, but not the same thing but anything additional?

The leak may or may not be coincidental, how do you know it wasn't near any electrics? It was above the Kitchen so would start the investigation there. Most likely the lighting, any ceiling lights that might have been near the leak?

Even if the leak wasn't near a light fitting there could be a junction box in the ceiling that was under the leak.

I take it you have tried unplugging absolutely everything you can and seeing if that makes any difference? Could be an appliance that is causing it.

But I would start with the Kitchen lights these things are rarely coincidental when there has been a leak.

There is no picture.

why is my earth trip allowing miserly load on each circuit but never a fuse trip?

Hi, Thanks for your points. i am struggling with a lap top, no desk light (well, I am notallowed to add it) & the busy pages are difficult to navigate. I posted a pic. but accidentally to the post before you but expected all could see it. Loading on my laptop and attaching was a struggle.

I removed nearest ceiling light & opened sockets in wall plaster & pulled + & earth but no difference.

It so petulant in that it seems to be saying, regarding circuit loading, "oh, 3 items no. Back aGAIN (EARTH LATCH BATTLE, okay, you win. No, changed my mind"

Never a circuit fuse trip, always earth latch which I have battle for it clutches mechanism & may locks on.

Is that mechanically normal - no slipping & when grips it will fail to latch.

I am tempted to open up open it tomorrow & hope to bypass just to let me give the fridges a go.

I do have electronic knowledge.

Still with no toilet till this is sorted.

Any light or added milliamps below even 1A trips it.

Surely, if not sodden (wasn't) it would be drying & getting better? I used the gas cooker to dry anything.

Thanks

Hey, I’m not an expert but I looked into this a bit and there are a few things that might be going on. Sometimes RCDs trip with very low loads if there’s a neutral-to-earth fault or a small insulation issue somewhere. It might not show up until something is switched on. Also, if a bunch of circuits or devices each have a little leakage, it can all add up and push the RCD over its limit. There’s also the chance the RCD itself is just overly sensitive or starting to fail. I’ve also seen people mention things like moisture or wiring issues in lights or switches causing this, especially in outdoor or older setups.

If it were me, I’d try turning off all circuits, then turning them on one at a time to see which one causes the trip. That might help narrow it down to a specific area or device. Let me know if you want help sorting through it.

Thanks. Apologies for delay but comm's. difficult too. New toilet leaking connections too - water caught, not spilling.- all dry. Crazy here
