distribution board

[Sonia Norman]

Hi

I was wondering if anybody has come across black stub slv? My mums church consumer unit is a nightmare. All of the connections are black stub slv, with half on them not marked as live. Thats ok for the ones that were already connected in the board. But in the board were some wires just connected loose in connector blocks! None of the circuits have an earth either. The main earth bond is there, i have just never come across a board that does not have a seperate earth with each circuit.

Not pyro, by any chance?

By black stub slv do you mean black stub sleeving i.e MICC cable conductor sleeve??

If so, the outer the outer sheathing of the MICC cable is the CPC and tbh, you wont find a lot better even after 30+ years.

What problems are you having??

Yes I've got loads of stub sleeve in the shed, along with all of the other parts of MICC terminations.

What you have there is a type of cable called MICC, it is the preferred cable type for church wiring. As for having no earth I very much doubt it, in fact I'd go so far as to say it most certainly does have an earth on every circuit!

Stub sleeve is exactly that, a sleeve, it is put over the bare conductors and the 'stubs' of the plastic seal of the termination.

I'm shocked that someone who is working in a church doesn't know what MICC is, what cable are you installing if not that?

Does it look like this?

 

[Sonia Norman]

Quite possibly as this I havent worked on this yet. And plesd dont all start shouting. I have another electrician coming in to help I just want to have some info before hand.

I am not installing cable, I am going to change the distribution board as the current board is an old rewireable and in a shocking state. I'm doing it free for experience with guidance.

Another electrician? Did the first one not know what this is either?

There is going to be a lot of shouting I'm afraid! An electrician who doesn't even recognise a common cable like micc when they see it is not an electrician in anyone's book! Even if they are incapable of working with this cable an electrician should recognise it, especially in a church where it always was and often still is the only type of cable allowed!

I suggest you shout at prospects college then, because they never once showed us this.

Stub sleeve?, I know as neoprene.

 

[uksparks]

That's going to be interesting changing that! It would be nice to see a picture.

So if this is being done under the guidance of an experienced electrician how come you're not asking him/her what it is and how it should be dealt with?
I'd be pretty ticked off if I found an apprentice was scared to ask questions on site, perhaps mostly ticked off with myself for giving the impression that questions weren't allowed. It's how an apprentice learns.
I must have driven my mentor mad while I was a boy.
