Wot a job to start back to

[Aindowsimon]

A test of a 2008 flat . Expecting an easy one boy was I wrong hear's some pics

And....

O why isn't this socket not live ??? ......

Oooooohh

That's nice
Why can't I plug in my tester????

Ohhhh .Yes on the live pin !
Nice termination

At least it's not just the one flat .....

I could have been taking photos all day but I'm not a paparazzi I'm electrician and had quite a lot to do as flats getting handed over tomorrow.
And have 4 more flats to test

What happened to the photo in post # 27??

Still no real conclusion, but it does look like this is a service head extension, which i'll still say is more likely to be a busbar chamber than a multi fuse distribution fuse set-up!!

With you on that, not much doubt.

Seen them individually fused but larger and usually for industrial units, etc.

I've never seen anything like that before.

No eng54, it is multi way, 200amp normally per phase, then ripped down to 100amp for outgoing on each busbar. They are nice units to work on.

Hi,

Nice job, spoilt by the termination of those SWA's, don't like that at all. What's wrong with a nice bit of tray to dress your cables onto and as Boydy says correct terminations on the end; not Earth Clamps and single insulated tails.
As for the live pin in the socket, what can you say!


Regards.

How about "OUCH YERBUGGERMAN!!" ????

Well if you're sure about it!! But it seems like an awful lot of bolts to remove, just to get at a single blown fuse to me!!!

Wot do you guys think on coding on the swa non termination and no double insulation ?
I'm crap when it comes to coding I'd like to give it a code 2 , but ...... Like I say I'm hesitant !
Before I go to my go to guy for advice , I'd put it to you gentlemen

I realise it's difficult for you guys to judge not seeing it with your own eyes the environment it's location ect , it's in a cupbard locked away from joe public

on my opinion on the costumer side definitely you have to terminate on the metal box and earth them to consumer unit..on the meter side you have to change all switches after meter with metal box fused switch and you can terminate them on the metal box plus you protect cable by relevant fuse plus you avoid problem with non double insulation cable..this its what i do if its my job..

I'd go with you on a code 2, especially looking at that earth.
On the other hand, one of the cores is the earth. How are the swa's terminated in the flats? If they're glanded and banjoed it's a different story. Just a mess. Then make a point of the single insulation.

 

[guest119]

You dont want to be messing with the wylex switches, they belong to the DNO and you would need to break the fuse seals to kill it. And there doesnt seem to be enough length on the swa to do that.

After a quick look I would suggest pricing for something like this.

Fit a 100x100x50 metal box below each cutout.
Use longer screws and spacer sleeves if required to stand the box off the backing.
Gland the swa to that.
Take the earth core out of a 20mm knockout with a stuffer and up to the earth block with another from the banjo (fryin pan if you are a Jock :ciappa
Continue the unbroken blue and brown through a short kopex to the switch.
230v label on box lid.

Maybe the same setup in the ceiling at the flats. IE metal box to terminate swa and continue unbroken through with the 3 cores and suplementary for the box/armour.

As if any of this work is going to be done!! You're living in cloud cuckoo land, it's been in place for several years now and changing it all around now (apart from costing an absolute fortune) just isn't going to happen. You'll be disrupting every homeowner in the building in the process too.

Any code 1's or 2's non compliances you'll have to prove. The SWA method of termination will only warrant a code 3 at best, this is only a thoroughly bad practice, rather than a non conformance. The only real possibility of a fail coding i can see from the brief overview that i've read here, will be in the SWA sizing to the further most apartments if were talking about a 4 storey building, but again, you'll have to prove that by calculation. If as stated, there are already 3 DNO fuses in place, then changing the existing isolators for switch fuses is pretty pointless, how many fuses of different ratings do you want in series?? lol!!

One more point, are those DNO split concentric cables 35mm?? They sure don't look like 35mm to me....

 

[Aindowsimon]

You are quoting some assumptions from other poster's eng
. I appreciate the input .
I've not say'd anything along the lines of 35mm concentric , or changing switch gear.
I agree, my client will not grant the works for cost reasons I'm sure , she may well one of them I have 1 more client in this building ! Unfortunately ( I don't mean that ) . Tbh in respect of everything else you say I agree solely . I was going to struggle to code as two as really no imminent, or real potential for danger . Just quite a bit! of non conformance issues .
You have highlighted my biggest problem hear , as there is more than just my couple of flats hear and not to much space for a good rectify job to be done on one hear and one there ( sub main ) , just no space available the DNO has not made life easy for me either

Just a note I think !!! DNO cable is 16mm

 

[richy3333]

My money is on a Lucy/Ryefield/Bemco unit at the incomer.
100a fuse per supply and 80a in the series 7 units adj. meters.
You will possibly not be able to access this as it will/should have a DNO suite padlock.

Oh, and D.I. is Detective Inspector :biggrin5: (Think Taggart)

Thats my boy(dy) - think like a Scot.

BTW I thought DI meant Electrical Trainee?!

Exactly, i was commenting on those that were commenting on what they thought needed upgrading and what they would do within that intake space.

Well if you're sure about it!! But it seems like an awful lot of bolts to remove, just to get at a single blown fuse to me!!!

If you look at the pic, 2 bolts (point of sealing for mops) on top its split that top half is where all the multi ways are, the bottom half is were its all bolted DNO domaine.
