Extending 2.5mm in a backbox

[ian bagshaw]

Hi,
Just replacing some kitchen sockets and the existing wiring wont reach the new sockets as the N & L are reversed. It's been a while since I did any of this as my qualifications are in industrial electronics. Firstly can I use 30A connector block? or Wago connectors? and if they wont fit in the back box would I be allowed a solder joint with heatshrink?
Many thanks
Ian

yes

 

[ian bagshaw]

Yes to all three?

I would try a wago ...

If space is tight, I find I have much better success with the Ideal in-line splices.

 

[kenny7askew]

yes as with Murdoch wago would be my preferred method

 

[telectrix]

wagos OK, i prefer the ideal in line connectors as per sparkychick.

How many cables, not conductors are you looking to join in this box?

The worst case scenario is 6 in one box mostly its only 4 or 2

^^ I would reconsider the choice of sockets, to avoid unnecessary additional joints.

Personally I wouldn’t solder, melting point of solder is pretty low - this will melt first. Preference would be Wago (32A) connectors first and then inline crimped connectors where space is a premium. I would also consider using this box for connections only and use a blank faceplate. This allows inspection and identifies what you’ve done.

i think if the temperature behind the sockets got up to the melting point of solder (180 c ish) you would have other things to worry about

Agreed Kenny, lol, you would. This thought was based on seeing tests in the past on various connectors during an deliberate overload. The connectors; wago, crimps and the classic terminal block all did well despite melted insulation. The soldered connection faired badly because the mechanical connection fails asap the solder starts to melt - this demo just put me off the idea.
