I'm in the process of replacing a wall mounted double socket with a recesed unit. However, as I'm also moving the position of the socket unit I no longer have sufficient length of cable from the ring circuit (2.5mm2 Twin-core-and-earth cable).
I could lift further floor boards and replace the entire length of cable. However, it would seem easier to simply add an additional lenth of cable. My question is how do I do this. I was presented with a confusing array of products in the local DIY store (junction boxes etc?) and need some advice.
Many thanks in advance for any help.
