To the op sparky 23 has gieven you the correct advice.
As I expected you guys who believe soldering and crimping is acceptable have taken one reg and interpreted it with a total disregard to any other reg.
See iee reg 526-03-03.
Soldering and crimping is definitley not acceptable in the way you guys use it.
To paraphrase...
[code:1]526-03-03: Cores of sheathed cables from which the sheath has been removed... ( blah, blah, blah ) .. shall be enclosed as required by Regulation 526-03-02[/code:1]
needs to be in an enclosure if the outer sheath has been stripped...
[code:1]526-03-02: Every termination and joint in a live conductor or a PEN conductor shall be made within one of the following or a combination thereof:
(i) blah
(ii) blah
(iii) blah
(iv) an enclosure formed or completed with building material considered to be non-combustible when tested to BS 476-4
(v) an enclosure formed or completed as part of the building structure, having the ignitability characteristic "P" as specified in BS 476 part 5[/code:1]
So, by my reconing, plaster is prety much non combustible.. so plastering it into a wall is allowed..
however, it does seem that just crimping and heat shrinking in a floor void for instance is a no no.. unless you put the crimp connection in a non combustible enclosure
I'm not disagreeing with you Holmslaw.. I would definitely prefer to see a cable replaced rather than crimped.. but in some circumstances there is no other choice..
