1mm attached to a 20A circuit

[vitoboy]

As an upshot of the other relpys that were unhelpful..
Can I ask how you would have described the situation I'm trying to get assistance with .. ?
I think we can agree it's not a straightforward situation.. and hard to describe without a huge essay.

Thanks again to everyone who persevered to an answer.

To the OP - I'm assuming that you've done the obvious thing and turned off all the other MCB's in sequence to find which is feeding this errant circuit? And, as daft as this sounds, if it's powered from this same MCB could someone have DIY'd the turning of a radial into an RFC? Only you know what you're looking at.

Yep .. only connected to that 1 20A radial .. no continuity to anything else.

When it comes to explaining what you have I often quote say what you see. The amount of reports I have QSd and had to ring the person asking what they mean and when explained I ask why didn't you write that.
From what I can make out you have a 20A device with both 2.5 and 1.0 cables connected, it isn't clear what the 1.0 does but becomes live when disconnected and the circuit energised. Is this correct?

Yep

Then this 1mm is interconnected somewhere
