Extending Cables - CU Change

[WayneL]

Hi all,

Need to pick your brains, if I can.

Doing a CU change - New Wylex dual RCD for an old 4-way rewirable.

Existing CU has a ring final, lighting, cooker and shower - so 5 x T&E entering CU.

The new CU is being fitted approx 0.5 meters away from the old one - and the cables won't reach

What's the best (neatest) way of extending the circuits to the new CU - I want to use this job for

my assessment.

I was thinking of an adaptable/junction box, situated where the old CU is sitting now, but this

would have to have at least 15 way available to extend each T&E.

Any ideas gratefully received.

Cheers

Large adaptable box and din rail with din rail connectors.

hi WayneL, allthough its not ideal to extend cables i understand that sometimes it must be done, so what i tend to do is crimp them, then tape them up individualy. I tend to use singles then, rather than F.T.E.
hope this helps,
Rizla

If you're crimping don't use tape, use heatshrink.

Din rail box would be tidy, mind.

I didnt think of that rocker!! good idea!!

Thanks chaps,

I'm tending to lean away from crimping as it's all going to be visible, not far from the new CU -

could look messy.

Have you got a link, Len, I've had a look around on the net, but it's hard to tell what will be

suitable without having a good look at it.

Thanks again.

put them in a bit of 2"x2" trunking going to your board.
the box and din rail does sound a class idea tho.
just make one your self, plastic adaptor box and fix a bit of din rail in it.

One of these....



With this screwed inside....



And these fixed onto it....




You can get them in a range of sizes with blanks and stop ends, even green and yellow ones for the earths.

Waaaa-go. Waa-aa-aa-go! Daylight come and me wago home.

D'ya reckon I could sell them the idea?

 

[WayneL]

Sorted.

Thanks everyone!

just a thought, but if you are going to put an adaptable box where the old CU was then why move the position of it?
and isnt a dual rcd board a bit OTT for 5 circuits?

 

[rocker]

Well it's that or a 6-way with RCBOs, 15 quid for a 6 way board and incomer, just under twenty quid each for decent RCBOs, that's 110 before we start, you can get good 60-70 quid deals on dual boards and plenty of spare ways.... I'd go with the 17th board every time, until the price of RCBOs come down, that is.

i prefer the din rail option much nicer, unfortunately trying to pass the additional cost onto the customer never goes down well
