Could this socket be causing circuit to trip every 3-5 days?

@Scotz74 - this might sound daft, but are there any audio/tv/av kind of outlet plates anywhere nearby??

For the others - I'm wondering if someone in the past has attempted to lash up some sort of clean earthing

Important point to note.

The black wire that is joined with the bare copper cables in the earth terminal, just because it is black doesn’t mean that it is a neutrual .
by removing it you may be introducing a danger to the installation that has not been considered. (This is true even if it “fixes” your tripping issues)

before doing anything else, we need to be certain of where that cable connects to.

It is just the black and not another three core cable.

Yes, but I can pull about six inches in but no more and doesn't seem to be part of a 3-core.

Thanks, I probably need to get a pro in.

Are the bare earths unsleeved in all the sockets.
