HI All,
I currently have a tall fitted corner fridge that i want to remove, but have found that there are 2 electric cables coming out of the ceiling surface mounted to the wall and going into a surface mounted double mains socket about 8 inches from the ceiling.
I need to sink these into the wall and run them down to nearer the floor and sink the double socket. How to I extend the cables so that they can be plastered (with a cover) I dont ideally want to make a hole in the ceiling and joint there and I dont want a joint box on the wall. How do I join new lengths so that I can plaster in the wall? i've extended cables using a joint box or wagon connectors but need something no bulky so i can recess.

Hope that makes sense.

What do you crimp them with? I'm only familiar with phone cable crimps
 
from a NASA document for which I cannot find a functional link
- Para 4.3 No. 4: Change sentence to “Crimping. Stranded wire shall be used for crimping. Crimping of solid wire is prohibited. Crimping of solder tinned stranded wire is prohibited.”

Two single solid copper wires in a crimped tube
The one on the right LEFT is a good crimp and should be reliable. The one on the left RIGHT is a poor crimp and will eventually fail.

If there is a void in the crimp then over time the copper which is under pressure from the crimp tube will creep into the voids
The pressure on the copper from the crimp tube is reduced.
Lower pressure results is a degraded contact from one wire to the other.

Yes, but didn't you get left and right the wrong way round?

Also, this was preceded by a quote that said "Crimping of solid wire is prohibited" (which is correct - with the type of crimpers likely to be used).
 
I think EFLI was suggesting you had the pictures back to front. I was just looking at the latest NASA guidance and it seems to have a lot less detail btw.
 
I know what a crimp is, must of used hundreds of thousands, but not an electrical one. was looking for a product ideally.
If i could hide it i would use a wago but I dont want to make a hole in the ceiling if I can help it. The joint will be a foot down the wall which i'll then cover and plaster so needs to be flat-ish.
