CU wiring too short for new board!

[FAA Greenie]

Hi Guy's, first post for me.

I have a client who has asked me to replace a rewireable fuse board for an 8 way split load board. No problem. Until I look into the existing board to find that the spark who fitted it took great pride in ensuring that the outgoing supplies were measured to the millimetre (Thou's of an inch to you oldies)!! to fit into the fuse terminals. Obviously this leaves me no spare wire whatsoever to get these wires into a modern 17th edn board. I have done prelim testing on the installation and all the circuits are fine so there is no reason to rewire any part of the installation. The existing fuseboard is in the garage and the client is unwilling for me to dig out and chase new cabling to the nearest sockets/lighting accessories inside the house to extend what i have to work with.

What is the easiest, safest, legal, easiest on the eye way to extend the little stumpy bits of cable i have available to give me something to work with?

I can, possibly move the board down a short distance, currently the circuits feed into the rear of the existing board.

Thanks in advance, if there is an obvious answer, i accept ribbing and critisism very well....

Blimey, you guys don't waste any time, thought you would all be down the pub.

Phil, happy with the din rail principle, sounds like a good idea, especially for future acess etc, i'll have a look next week at how much movement of the unit i have to play with, i reckon there should be enough (from memory)!!

Thanks very much

isit 1 box for each circuit???and cheers for pic

no mate all in one box. you can even get jumpers for them so you can interlink

Rail Mounted Terminals - Products

Anyone tried these?

got some and they are quite good, the electric ctr do them for half the price same sort of quality and size

isit a load of push connectors??

Cool Phil, though it's just for a domestic. Not the space shuttle......

they are for domestic thing i like about them is unlike the wago connector blocks these can take the 10mm for showers hobs etc. all neat and like paul said they can be mounted at the same height as the old board. the din boxes i use take up to 12 circuits

It's only his third post and he's taking the mick out of you Phil! I like this guy already

On a serious note re the DIN RAIL, how does this work with neutrals and earths. The new 17th edn box will obviously have it's own split load neutral terminals. Can i put a single 4mm neutral between each split load section of the CU to it's own terminal in the DIN box and split them up from there? Having thought about it, i can't see why not, any thoughts?

Thanks Paul!!

you pop the neutrals on their own mate. 1 terminal per conductor.
you can link them with the jumper bars if you wanted to. tbh i wire them in at the din rail and take them straight out into the new board. all marked up and neat.

i get mine from the electric ctr mate.

Phil, so just bypass the 'built in' neutral busbar altogether and use the din rail?
