Any thoughts on this old thing?

That’s not the right bus bar shield, surely??

Maybe my eyes are deceiving me, but is it a cut-off CPC on the incoming T&E?

Two 0.0x IR readings, one traced to outside light, the other on upstairs sockets which soared when a highly mangled iPhone charging cable was removed from a USB socket.

The charger must be broken then if it has primary (mains) to output (USB) lead continuity!?

Maybe I'm odd (OK, yes I am odd) but when PAT testing the likes of USB chargers, PoE injectors, etc, I treat "class II" testing with the earth clamped to a butchered USB/network cable so I can check for insulation failure inside. Thankfully not found a dangerous one yet, but you do read of the occasional death from that (often involving eBay fakes and a bath as well).

It actually is the right shield, I just didn't fit it correctly before taking the photo. It's fine now (honest!)

Yes, that was the main thing. There's a separate 10mm CPC but I didn't like the T&E being un-earthed. I didn't want risk damaging the rather short incoming T&E so I earthed it the other end (also cut off) and there's now a wago on this end and a notional 4mm to the CPC bar.

Yes, it was actually a plug in apple charger not a USB socket, my mind wandered!
The apple charge plugs are earthed, and I was getting a N+E fault show up. I binned the lot, but in hindsight some more tests would have been quite interesting, as it suggests a primary/secondary link/fault on one side of the coil.

The more minor thing that some would say is wrong with my install hasn't been spotted yet. It's related to an area of scrutiny that Westy specialises in....

I didn't know Westy specialised in the lack of grommet strips.

Fair! I was expecting some in the brown envelope and they were missing. I decided as the wall opening was higher than the lower edge I wouldn't lose too much sleep over it.

That still wasn't the thing I was thinking of though! It will be interesting to see how many more things I've done....!
It's something the original installer also did.

Polarity reversed at incoming tails?

Good God man you know how to make someone's heart skip a beat!
No, we both got that right!
(One of my biggest concerns was the length of the main N but it worked out ok, just!)

No, it's a very minor thing, as we all tend to be a pedantic bunch I was expecting someone to slap me for it straight away.
It would probably first be noticed if you had to test certain circuits.

Not familiar with that old incomer and didn't want to assume busbar connection to it, but lettering appeared to show 'L' above left terminal.
