...just out of interest...

[xAlex]

A friend of mine said that they nearly asked me if I could move a CU a couple of feet. I said "probably not if the cables required lengthening". Just out of interest, what would this involve? Would you just crimp/shrink wrap all of the cables to extend them? What testing would be required following?

Thanks,

Alex

If they only "nearly asked you" - why did you reply?

If you are asking this sort of question you should have said "no way" - not probably not - as you have just demonstrated to the world you don't have the competence.

As for the tests required - look in BS7671 or OSG or GN3.

Put the old ends into a Henley block and run new cable from there. This will make it so much easier if you need to replace the CU - or add an extra one - in the future.

Creameeg: I should have learnt by now that the background is not important. I am bright enough to work out if I'm competent to do a particular job. Asking a question does not automatically deem a person 'not competent' otherwise no one on this forum would get anything done. I did say, "out of interest....". I'm just trying to educate myself.
Thanks for the response re. the tests.
SpaceCat: So the tails from the meter could go into a henley block, but what about the circuit cables? Cheers

JB the circuits, thats what I did when I replaced 2 CU's and a 1way insulated switch fuse board with 12 way split load CU, fortunately the CU's were under the stairs. I JB'd the wires under the floor on the hall landing and under the floor below the CU and used the existing henley block for the tails.

When I replaced my own CU I used a Wylex REC2S 2 pole isolator I got off one of the lads from CES/YEDL/NEDL/MetersPlus

I fitted the REC2S to the meter board and when MetersPlus came out to change our meter the guy didnt know how to wire it, I had wire it for him

Gtd, that picture is just SO familiar. I've got the same service head and what looks like the same meter attached to an almost identical bit of wood fixed to the wall with the same ceramic washers. Even the colour of the wood is the same, but it was something smaller that first caught my eye.

THAT'S MY BELL TRANSFORMER!!!

I'm not having a go at you and would be amongst the first the see the educational value of this forum. However, in moving a CU you are either going to be working with the tails on the supply side or altering the circuit cables on the distribution side. Quite probably both. In either event I can only hope that by asking the type of basic questions that you did (which would be covered in some detail even on a Part P course) you have seen that you are not competent to undertake such work. Executing testing properly is basic and fundamental to competence. To ask what the tests are immediately confirms incompetence. Happy learning.

I thought that I had stated that I did not contemplate this work. I will remember to make this very very clear next time, although others seemed to have realised. In asking the question I do prove that I am not competent to do this work. Again, others took this for granted and did not find a need to re-state. I don’t think that anyone will read your last comment and not find it, or other elements of your posts above, slightly condescending.
Unless we know-it-all, we are all learning. So may I wish you the same?

Moving a CU is always feasable but if cables need to be extended then a major alteration is required to all ccts involved, which means full testing would be required.

You didn't state why it needed to be moved and of course is it essential or desirable to move it.

I have just relocated a CU from a garage to a downstairs cloakroom, the other side of the wall, all ccts required extending so I used an enclosure with a din rail and din rail mounted connector blocks to feed throught the wall.

JB the circuits, thats what I did ...... I JB'd the wires under the floor on the hall landing and under the floor below the CU .......

JB the circuits, thats what I did....

I hope you fitted a blank to the CU, and then bought a crimping tool and crimps with the money you saved !
