Moving CU to new position,

[MICKYSPARKY]

Ive got a slight problem, customer requires CU to be upgraded and moved about 8feet away from origonal position.
Im goin to put it next to incoming supply, only trouble ive got is all extended cables require jointing and are all going to be face fixed as i cant hide them, ie PVC trunking. Junction boxes are a no no, other than crimping is there any other conectors on the market i can get. existing CU is at ceiling height, but i cannot access under floors.

The last time I had to extend every circuit I used a customisable box with DIN rail and push spring connectors (similar to what's inside a maintenance free JB). I can't remember the make I'm afraid but if I get time in a bit I'll try and find out. I labelled each circuit inside the box. Looked very neat.

micky wats up with junction boxes sounds like they will be accesible you can still do a nice neat job using jbs theve got a bs number

Thanks Kingeri, sounds like the answer to the problem, if you find the make it would be great. is the item an inspection box with a DIN rail fix in it.

I would also use DIN rail, we use a wide variety of adaptable boxes and J'Bs with DIN rail and its the neatest option IMO, depending on how many circuits you could also fit a small piece of slotted trunking to make it look super neat. I think ive got a pic of one that i did recently i will try and upload it.

basically an adaptable box with a din rain. wago do some nice din rail connector blocks. if you can't access under floor from above, can you cut a section out of the ceiling. use maintenance free connector blocks, then reinstate the ceiling.

Thanks Farmelectrics. the m,ain problem with Junction boxes which i usually use, but iv'e nowhere to hide them. all above floors are ceramic tiled and ceiling is specilised finnish.

customer said no to both.

​bet they'd allow it for a shiny new kitchen/cooker/shower that they could show off to the neighbours.

ok take the lads advise then nice jb with dim rail etc

Heres the pic of the DIN rail JB, excuse the wonky conductors it was lashed in for testing!

We also use adaptable boxes/JBs with clear lids for inspections, although for a domestic installation its probably not necessary (unless you can get DIN rail mounted RCDs/MCBS?! although i doubt you would be using them if you are just extending the circuit!

I can't find the exact things I used but you should be able to find what you need quite quickly. Just make sure you sticker up the box 230v and label the circuits inside the enclosure. I had the cables entering the box from behind and leaving at the bottom. You'd probably want to avoid having them enter from above if using T&E so as to not mess with the IP rating. Max has used flexible conduit and glands - I didn't do this (it was a domestic job).

Max, that's a really neat looking job!

I like the DIN rail solution using DIN Wago's as suggested earlier by Telectrix.
Also since it not been spoke about, I'm assuming the CCU move still means the tails are less than 3m long?

 

[Farmelectrics]

nice neat box max must admit never seen one in a domestic dwelling before but if youve got the space and the customer is happy job done

I also would use adpt box and din rail option , with CTS glands on entry

Why does the customer want the CU moved in the first place, is it in the way for something else. If so putting a large JB enclosure in its place defeats the object i would think.
Crimp and heat sleeve the circuits in to some surface trunking would probably look better if the above was the case.
