Hi all,
As the title suggest, I have today replaced an old (1977) Wylex fuse board for a nice shiney 10 way consumer unit. However, when I took the old fuse board off the existing cables gave no slack, not even a smidge. They were solid and with just 200mm of cable left hanging out of the wall.
This was obviously not enough so I had to extend them to reach the new terminals in the new box. I have surprisingly not had this scenario for a very long time, so my dilemma now began. Do I use wago's, choc boxes or butt crimps? I opted for the crimps but also added heat shrinks to them as I did many years back when doing this. Probably a mistake, but I felt more comfortable with this despite the reliability of wago's.

Would you guys please let me know what you would have done given this scenario? A rewire was not an option before any comedians suggest it. ;)

Everything tested OK by the way. I'm just concerned about the longevity of crimps compared with wago's and choc boxes. They all come loose over time.
 
I had to extend a cooker circuit on my last CU change, used wagos for the 6mm twin and earth. the 3 pole red ones are good for upto 6mm and 40 or 41 amps. for the smaller sizes I tend to use the orange ideal inline connectors. not had a problem with them yet.

Arent those red ones just push in? You can't re-use them so they seem to be more permanent. I should perhaps read up more on them.
