SSE Electricity supply work i seen

[Carnegstar]

Heres a picture i took on my phone at the beggining of this year on a job, what does everyone think?



Their orange cables supply three flats and a common close meter.
We took one week to install metal trunking for these to run along up the stairs, to prevent damage or tampering

It’s not my field so I’ll ask.

What is the situation in flats where the freeholder wants a DNO supply direct to a leaseholders property?

It’s a not something I’ve ever even considered before. I did run a property management company a few years back but this never arose.

Tony - usually we would run Split-Con like this from the original service position to a 'Red link' cut-out and meter in the 'leaseholdrs' property, the red links are solid links and the 1361 fuse would be at the main service intake (usually in a ryfield). This means that the supplies to each flat would Be TNS derived from TNCS.

Wow that's appalling worthy of a third world country. Never seen this type of work in this country. Beggars belief !

a Suedo TNS system, that will still be TNC-S to all intendant purposes. I agree, a small ryefield would have been a much better solution to supply these three flats, but still with the main cut-out BS1361 HRC fuses located in the service head, where they should be!!

Dogs dinner!!!

I hope that's temp, ring the DNO and tell them you've been hurt by their recent install, you laughed until your sides split...

a Suedo TNS system

Is this a chinese phrase for shiite?

certainly seems like it from the replies on here :lol:

Other then that, the single insulation on the concentric is the worst 'fault'
That is split-concentric (seperate Neutral and earth, usually four strands of the outer are bare and used for earth, the rest are sleeved blue and used for neutral) and as such the supplys to each flat are usually TNS.
The neutral/earths all connect into that Henley block which then has just A Green/yellow 16mm connecting it to the PME terminal

Altogether fairly rough I would say - are you sure its not just temporary until a new Head is installed?

I think this orange concentric cable only has sleeved bl?ack conductors around and no bare ones for the earth, where they all are neutral. and I also believe it has the aluminium core.

So might this cause an earth path break in the flats? surely a protective earth should be supplied to all the flats heads too?
say if one was disconnected or loose? The connections at that henly block are not as tamper-proof as the ones ive seen at any other head - no seals? obviously if it is not slit concentric as mentioned above but i dont think it is split in the flats, only like the head to the left of it.

And im sure its still in service

 

[Carnegstar]

So could these flats have TT supplies then?

No, but this post is more likely to be a bit of Perth ****e.... lol!!

The new orange concentrics are supposed to have earths and neutral in them, so the flats are TNS, unlike a couple yrs back when the easy to terminate black concentric with live and neutral and TNC-S, i believe they changed it because a loss in neutral to the flat would mean loss of earth (Obviously)

 

[Engineer54]

Will someone please explain to me how these 3 flats are going to be TNS?? Look at the main photo again and tell me where the earth connections to these flats are going to be derived from!!!

 

[Knobhead]

This job’s got me intrigued now. Wonder what the other end is like?
I know my eyesight is bad but I should have spotted 16mm earth used as neutral.
Could base a competition on this, spot the bit that’s right.

 

[somersetsparks]

Its basically just a TNCS supply with 3 distribuiton circuits (with seperate Neutral and earth conductors) feeding remote cut-outs with solid links in. Fuses should be at supply end.
Maybe its not Split-con every one of these ive ever done has been.
In all seriousness though, I imagine that is a temporary job, until a service renewal is done, they would never allow that workmanship normally!
