Re-Locating Fuseboard

[sl1210]

Hi guys,

Need to quote for a job where the customer wants the consumer unit re-positioned to the other side of the wall its on at the moment. Basically it used to be in a cupboard, but now that cupboard has been joined to the bathroom, and they don't want to box it in the bathroom. Its a flush metal box, but there is a seperate main earth cable coming in, and all circuits have there own earth, not dependent on metal conduit.

I can extend all the circuit cables easel by crimping them, but not too sure what to do about the tails. They are 16mm singles run in metal conduit, and the isolator and meter is in the communal hallway. Whats the best way to extend them, baring in mind it might not be accessible, unless i make a big hole in the wall behind the fusebox??

Pulling new singles in from the meter cupboard is a possibility, but i don't know if i feel too comfortable doing that, incase i pull the old ones out and struggle to get the new through.

Cheers

use henley blocks to extend the tails. then box the henleys in but leaving them accessible by undoing a few screws.

the problem is the wall where the fuseboard sits in now flush is gonna be filled and tiled. so i can henley block but i would have to make as big a whole as i can behind the new fuseboard position so to access the joint. i'm only short a foot or so. is there anything smaller than a henley block that i am allowed to use, like a big connector block or wago??

nope. can they not make a tiled panel which can be detached for maintenance?

Its a solid wall not plasterboard so probably not. I think i can get most of the cable through the wall and into the new fusebox position if i mount it higher, so a henley could definitely work. I guess it will have to ;0))

You may be able to pull some slack down from the floor above and most cables may reach, so it may not be too bad of a job

16mm through crimps and heat-shrink, just need the bigger ratchet crimp tool

Personally, I would try to put in new tails with no joins (albeit with a switchfuse if required). I just prefer to keep joints to a minimum whenever possible

But you've seen the job and I haven't, so go with what your're comfortable with.

crimping would definitely be the easier option. i just don't like crimping anything over 6mm. but might have to. have you used 16mm through crimps on tails before???
