If you are going to plaster over the cable again then you need to either
solder or crimp the join and not use screw terminals. Sheath the
individual wires and the overall cable in heatshrink as well.



And what about this discussion, previously held on this very forum?

I'll be honest, guys - I'm getting confused.

Here's the situation. I have some ring main cables coming out of a concrete
cladded wall.

For reasons of a damp proof membrane, I had to pull the cable out from the
concrete up until around 1.5 metres high.

I bared the wire in parts while doing this, so have had to replace that
patch of cable.

I now need some safe and reliable method of joining the old ring main cable
to new. I previously used terminal blocks but I don't think they're safe.
Crimping appears to be both a dark art and dangerous. Soldering sounds like
the next best option but does this simply involve a standard soldering iron
+ solder (as we use to make circuit boards)?

Help will be really appreciated here.
