It can. But do the joint properly and it won't
Indeed, but it has recommended to buy a new cable from the start.Then compare cost of buying new cable with the cost of a "proper" joint,
It doesn't have to be. It can be 25 amps. The cable is rated up to 27amps depending on installation methods. It won't instantly catch fire above that value.
That is not what I said. I said "2.5mm cables will not catch fire at 32 amps."I fully appreciate that you know far more about this than I do but I am confused by your earlier statement that 32 amps is fine on one leg. If that is the case why can't a radial be 32 amps?
That is not what I said. I said "2.5mm cables will not catch fire at 32 amps."
Choc bloc in particular is often of very poor quality or badly installed. I've encountered so many problems (yes including fires) with choc bloc/2.5mm²
Buried in masonry is the same rating as clipped to surface.AFAIK, 27 amps is for surface clipped cables. How many houses have rings that are surface mounted? 20 amps in trunking.
Then stop waffling about how to join ends of cables together,Indeed, but it has recommended to buy a new cable from the start.
but a defective joint could overheat enough to create a risk of fireThat is not what I said. I said "2.5mm cables will not catch fire at 32 amps."
Note also that the load at the end of the spur is limited to the sum of the fuses in the plugs. Maximum would be 26 amp ( two 13 amp fuses )Note that a spur off a ring in 2.5mm2 cable is protected by a 32 amp MCB only.
A double socket with 2 unfused 2 way adapters each containing plugs could be 52 amps. But you know that anyway.Note also that the load at the end of the spur is limited to the sum of the fuses in the plugs. Maximum would be 26 amp ( two 13 amp fuses )

You know the bit where your old sparky mate was very keen on there being unbroken cables. And then the bit where you don't know the answer to your question. Well you do, if you think about it for a moment.I ran a lot of cables at my place with the help of my old sparky mate whose sadly passed; otherwise I would ask him. When we worked on my house he was very keen on there being unbroken cables between sockets, so that's the reason I don't already know the answer to this.
Why stop at 2 double sockets on a spurA double socket with 2 unfused 2 way adapters each containing plugs could be 52 amps. But you know that anyway.
That is not so. I could be 27A if there were such an MCB - so 25A.Apropos the spur, given that a 2.5mm radial is only permitted to 20amps,
Yes, without buried conduit; trunking is not for burying.When you say buried in masonry, do you mean plastered in without trunking?
Yes conduit, buried or not, is less - because the heat is not dissipated as well.Most of the references that I have come across say 20amps in conduit. Out of interest, why the difference?
I guess that's for nafarious purposes!Why stop at 2 double sockets on a spur
