How to deal with Pyro Cable?

[Mattja]

Situation is there's some 53 year old pyro cable that I need to either remove, or make dead, or cut short and push back into the wall having ensured that the still-live end cannot short out the circuit or come into contact with anything.

No hope of fully removing it, as it goes up the cavity and I don't even know the route it takes.
Chances of finding the junction box that connects it to the downstairs power ring are remote, I suspect it connects at a junction box fixed into the wall behind fixed cupboards, next to pipes, in a kitchen, and below the bath (bathroom above the kitchen), however I cannot be sure. I also am not sure I can take the cupboards down without damaging them (I'm no carpenter/kitchen fitter).

SKIP TO THE POINT:

The obvious thing to do seems to be to cut the cable just after it leaves the outside house, fix the end in such a way that it's not going to short the circuit or make live anything it comes into contact with, and shove it back into the wall (then cement over it). I've not had to deal with pyro before, how would you recommend going about this?

Indeed! I have a full kit of MI tools for all sizes of pots including imperial, not to mention a small oxygen/gas torch for drying/annealing/silver soldering as needed, various roller straightners, blocks of wood with grooves cut in them, rubber mallets, bending levers...

Cashnotakite carries a roll of tape and hammer from what I can tell. Daz.

The tape for his fingers after squashing them with the hammer?

Sad really, how such an every day task, for any sparkie worth his salt. side of the times.!

Whoever you call will need the tools to terminate the cable and probably an imperial gland, pot and seal to make off the end correctly. You cannot just cut the end and whack it in a junction box. It's a very temperamental cable if not treated well, not unlike my wife!!

No,no definitely not gramps. By the time you've shelled out for glands, pots,seals,neoprene,stripper and a crimper because only old geezers like you still own them its not worth it. I mean, dont get me wrong, as an old soldier who's spent years grumbling in the game like you knows full well you still charge him full expenses. I'm sure you've pulled more than a trick or twenty like that over the years

cliff notes: rinse him and move on

I must be getting old, I just can't believe that anyone working as a spark does not know how to terminate Pyro. I love pyro, easy to use, looks neat, lasts forever (well near enough as no plastic to deteriorate.
Do they not teach this nowadays?

Are you. Saying that there is a single pyro cable leaving the house spurred off the ring?
If this is the case can you not re terminate the pyro into a suitable IP rated box fixed to the building terminating the conductors inside.

Not used pyro for some time it is a bit of a black art now and would think that not many sparkies would be able to do it nowadays.

Might be worth carrying out an IR test on the circuit prior to carrying out any work on pyro. Should last for ever if not disturbed but worth checking to confirm condition and if your work has caused any issues.

Would be interesting to understand your competencies, qualifications, and experiences following your initial comments and suggestions.

Pyro is a great cable, we will soon be starting a big lighting contract in a very old church and all the cabling will be bare pyro. If it's installed correctly and dressed right it just disappears after a while. I think I'm right in saying that most, if not all older churches must still be wired using it.

I wish it wasn't so expensive to buy, I could use it much more then!
The 25mm 2core here is around £65 a meter.

MICC Simples, no way is it a black art, honestly. Lost art maybe.

I brought 30 meters of 2l1.5 this week from CEF..Took them 4 days to get it in though as apparently had to come from Wales £75 +VAT.

you can't just bury a live cable. nobody will know it's there unles there's an accessory or a blanked box to indicate the presence of cable.

Some will start saying FP200 is difficult to work with next
