How to extend cables neatly when replacing consumer unit.

[grumpyjohn01]

Try using the ideal inline tooless through crimps, if extending inside the enclosure on smaller cables, it's neat and timesaving.

Yep my go to for solid cored cables, much better than crimps (has anyone ever seen a current rating for a blue butt crimp? or any other red,yellow, blue for that matter..) , quicker as well

@westward10 I've actually had a similar issue with them being inconsistent connections. Extended a heater connection with them in an ideal box and was getting high readings opened the box and they were good, closed it and they were naff. Ripped the lot out and used wagos instead, perfect readings!
I actually managed to pull one off a 2.5 conductor with very little force and no twisting.
The box I bought is still in the van bar about 6.

Never had these problems but now concerned to hear that others have...will buy a box of the ludicrously priced wago inline ones next time

Looking on here as to the best way to lower my CU and have seen the wiska box and the thought struck me, couldn't a box be produced that had bus bars for the neutral and earth with provision to extend with 25mm cable and then connectors for the individual lives? Non-electrician but would love to know if my thinking is right or wrong

Having all neutrals commoned on outgoing cables would be problematic where more than one RCD is present or where such protection is afforded through the use of RCBOs. Even if this wasn't the case, future upgrades would be problematic.

Commoning outgoing earths would be less problematic, but would make fault finding or testing more difficult.
