Extendng meter tails

[NozSpark]

I've got a job coming up to relocate / replace a CU.

Now the existing tails come up from the meter cabinet within the wall to the existing position, I will be adding an enclosure to extend all the final circuits (I'll probably use DIN rail terminals),

but what's the best way to extend the tails??

More DIN rail terminals, un-insulated crimps and heat shrink or something else?.... I will not have room for Henley (ISCO) blocks!

Could you not pull some more through?

If you are going to extend do you need to fuse protect the tails?

That may give you your answer.

Else,why no Henleys, but you can put DIN's in an enclosure?

No mate I can't..... I would normally replace the whole length, but in this case there's no chance,,, fully fitted kitchen highline units in the way..it'll be awkward as hell as it is

Crimp and heatsleeve sounds like a job i would price to not get.

Can you through crimp them within the enclosure ?

There's already an ISO switch in the tails, I was considering replacing it with a KMF (fused switch)

I doubt that I'd get the Henleys in the enclosure,,, I know, I know,,,,,, bigger enclosure

That was the plan Deke!.... Maybe?

I use uninsulated crimps. I cut back the sheath about 1cm further than the insualtion. i then use a layer of glue lined heatshrink first which just fits in "valley" between the ends of the sheaths. Then another layer of [standard] shrink same length. Then a third layer overlapping the sheaths 1cm. Then a final layer overlapping the sheaths 2cm.

I had a similar sounding job a while ago. I left the old consumer unit in place as a connections box with Din rail connections for a few circuits but a Henley block for the tails as i did not trust the possible 100A through a Din rail connector. Fitted blanks to the front and a 'isolate elsewhere' & 240V sticker.

Now there's a thought Slips,,,, I could reuse the existing CU and fit a 100A switch to joint the tails,,, DIN rail terminals for the rest and some blanks over the top.... Not forgetting my KMF switch fuse
