My poor old nan!

[N2ETC]

Evening, my dear old nan has an old fuse box that she wants replacing with a new cu. The old fuse box is in her pantry practically on the floor. So even if she has it updated it will need to be moved. Now I haven't really had a look at it yet but if she can get it moved to the wall just outside the cupboard so she can access it easier the tails will need extending and I would probably assume the rest of the circuits. So whats the easiest solution please guys so I make sure that she is not ripped off and also its a neat job??

Fair enough mate. For what its worth we use a 4 inch adaptable box maybe bigger then use Wago connectors to extend cables but crimps are acceptable aswell although I cant stand em!

So at the point where the old CU was there will now be loads of connection boxe's. Will they be hidden in the wall?.

An electrician would expose the wires that feed the unit, then decide where he was going to put the joins.

Me too. 'Normal' Wagos for lighting/radials and the chunky bu99ers for RFCs. I used to use crimps but they have to be JUST RIGHT or else...and there's all of that heat shrink effort.

For what it's worth changing a CU is quite nervy first time bust as long as you're careful and methodical it's OK. Notification and full certificate mind you so allow enough time to test and certificate each circuit properly.

There's some good advice here. Watch an experienced sparky and see how it's done. Make lots of notes (and cups of tea)
