Neutral from next doors supply.

Yeah absolutly.
The wiring is all done in single running through the unprotected holes in the metal studs. The additional socket was connected to a brown, a blue and a green/yellow using Scotchloks, as chance would have it they got the wrong Blue.
As chance would have it the power of the set top box was insufficient to trip the RCD but enough inrush to trip the RCBO, once running the current is low enough to not trip the RCBO.
Scotch locks. That’s a new one for house wiring !
Who fitted it?
I’m surprised and worried it won’t trip the devices.
The house you were working in had an RCD then.

Yes the flat with the dodgy socket has a board with 2 RCD's they test as 18/21mA & 17/22mA. The running current of set top box is only 12mA [according to my cheap clamp mm] so below tripping current.
Neighbour has RCBO's, the ring trips as 14&17mA so the inrush is too much for it but running current is OK.
Are you seriously saying that the wiring was 6491x just chucked through the inside of a (metallic) stud wall! and presumably other building voids too? Oh yes, when I fished them all out at that point I found 8 each of brown, blue & green yellow in various sizes, all virtually unidentifiable between the 2 properties. I have raised it with the freeholders agent and NICEIC as there are stickers on both installation but no contractors name.

Wow!
I didn't see this first time around, but my first thought when you said scotchlocks and picked up the wrong blue was the same as Adam's. WTF, singles just chucked through a partition wall, and neighbours share the hollow wall
Mind you, I find the idea of having just that partition wall between flats rather disturbing. Wouldn't have thought it met building regs for noise control, doubt it meets regs for fire resistance, and it's not exactly secure since it takes bu**er all effort to kick through one (wonder what an insurance company would say if someone visiting, with or without permission, next door broke through and cleaned the flat out).

sadly this construction is fairly common in low rise flats: 100mm metal studs, double layers of PB both sides and filled with glass fibre - used to be rolls but now batts.I didn't see this first time around, but my first thought when you said scotchlocks and picked up the wrong blue was the same as Adam's.

Sometimes a layer of OSB or ply in there too.
I started to read this thread and as I reached half way I figured out two possibilities, that the socket is wired incorrectly and the TV box is using an earth as the neutral or is using a borrowed neutral from possibly a lighting circuit........ oh well no surprises, but the chap who added that socket should have used his neighbours live as well as he did use his neutral to get free energy!
