I've installed screened PVC trunking before, the data compartment was coated with copper. Super expensive.

Yes and obviously u can get screened data cable too

The advice given to me though was not to use it unless specifically requested, dunno how accurate that is

I used to do just 1st fixes back to comms cabinets and basic laying of cabling

Can't say network 'engineers' work to anything like our regs, to tell the truth.
Admittedly, standards are falling badly all round but comparing some of the thrown in bunches of IT cables with mains installs is, in general, a bit of a joke.
Engineer is an extremely loose term sometimes

I see a lot.of contractors when they scale up they suddenly become an engineering firm not to mention dropping the first name

So they start off as "Mikey Smith Electrical "

And then they change up to "Smith Engineering"
To be honest it's nice to see people not just using the 'First three initials + electric(al)' formula. I bet there's about 2000 'JBL Electrical's in the UK.

The story behind this. It’s a sub main from the main CU in a empty rental property.

I’m not quite sure but I think this is known as the “F*ck it, I’ll use the Australia method as I don’t know what I’m doing’!

I’m actually impressed someone could mess it up that bad. 😂

Surprised everything still operates. Is that some chewing gum they've left on the misplaced bus bar?

Im guessing that the power coming in is via the furthest right hand side breaker...

That is a special kind of badgers arse consumer unit , that is so bad its actually quite funny
Correct

It is fed from a 32a MCB in the main CU but this is where the right way of doing it stops.
Live is then fed to the far right 32a MCB in this board, with a link back to the RCD, the neutral is direct to the RCD. And every circuit is fed upside down.

Impressive to get it that wrong. 😂

I did think that when I first opened it up.
It’s a bit of mortar that’s dropped in the excessive opening at the top.

Aside from that is directly exposed, looks like a snake mating ball and needs to be in a wiring centre.

They have cut the earth from the stop cock (just inside the wall to the right) so there is now no earth to any of the pipes in the property. They choc-bloc it into the heating system to give that an earth (I think the plumber might have had a go here). I tested all the pipes I could read with my wander lead and none got anywhere near the 0.05ohm allowance. Lowest I got was 13.6

But at least they cut the earth off the metal sink/drainer as it wouldn’t have worked anyway. 😂

I think that's the best one yet or at least for a long while.
That would have made an excellent game of "find the incoming supply". May I steal this photo for training purposes?!
I'd found the live, but still can't totally fathom the Neutral as it looks like the bottom left of the RCD goes straight to the N bar....

My first words when I opened it up where ‘what the actual F!’

Of course, feel free.

I haven't touched that board yet. I've got to go back later in the week. So will fathom out how it is wired.

Property has 2 CU's. Both have 10 circuits. All 20 circuits are not labelled. So I spent 5hrs yesterday playing my favourite game of hunt the circuit for the first CU. Only reason I had the cover off was to see which MCB from the main CU fed that one.

I reckon it's someone from Europe - over there you feed the tops and the load comes out the bottom.
I have it on good authority from both Legrand and Hager that their MCB's can be used in both directions.

Looking at the gap between the two MCB's below the mortar snot, it would seem the busbar is not continuous as suggested by Tim.

Yeah, new CU. The other immediate thought is max demand / upstream protection given ?6mm incoming conductors. Hope it's SWA. Also might be a 2.5mm in a B32. Anyway, lots to investigate!

I think a new board is a bit extreme, especially if it's not damaged, (can't see the lid) Legrand is a very good quality product, re-wiring of the board is possibly all that is needed.

As a secondary board does it need a main switch, if all the circuits are protected by an RCD? Certainly in Europe the main board would cover that, it is now a requirement not to have a secondary board supplied from an RCD, but from a cut out switch and an RCD in the secondary board.

I wouldn't even consider rectifying that, off the wall and a new unit fitted.
Why? Doesn't seem a lot wrong with the actual board it's just the wiring that's hilariously crap. Unless customer wants an RCBO board it just seems like an extra £100 for a new unit plus the work of getting it on the wall for no real benefit imo.
