MCBs tripping randomly?

[nicebutdim]

The statistical probability of both old and new MCBs exhibiting the same inexplicable fault isn't worth considering, so there's either a rational explanation, human intervention or this thread is destined to enter rather exclusive territory.

Could you post a photo of the consumer unit with the front off

All the photos I’ve took are too big to upload to this site, not sure how else to to show you.

Try taking a screenshot of the photos and also crop them a bit if there's any excess around the edges.

My money is on human intervention rather than anything electrical.

Haven't looked inside of one for a while, but I take it electronics hasn't found its way into MCBs yet, making them possibly vulnerable to so called smart meters.

We do have a smart meter plugged in, in the kitchen which is the downstairs ring. I’ve had that unplugged though multiple times when trying different things.

There is only me and my partner in the house and neither of us are doing it in purpose.

The mechanism inside any MCB that I've dismantled to date is fairly simple, and, if the MCB is in working order, there is no possible way it can be 'tripped', other than by doing what it's supposed to (which it's not, if no outgoing cable is connected), or perhaps by a mechanical shock, such as hitting the side of the fuse box with a hammer.

Any electrical explanation is far beyond my comprehension, but I desperately want to see this thread resolved - especially now the same fault has manifested itself in the same breaker in a brand new board and with no load connected.

Just to confirm.

the original summer house was experiencing random trips
it was fed from a normal mcb

the board has been changed and the same thing is happening with the new equipment

the outgoing live cable has been removed from the circuit breaker and the breaker still trips at random times.

if all the above is correct, i would be looking for a mechanical reason for tripping as mentioned above by @DPG

I would be considering a covert ip camera watching the board with the cover off and seeing what is going on.

edit,
A video of a breaker tripping on its own with no outgoing cable attached would really amaze me.
if that happens, i would be recommending posting on a forum that follows ley lines, ghosts, spirits, extra-terrestrials, EMF and grounding, etc.
