Discuss MICC/PYRO. CABLE FAULT. / FUSE NOT BLOWING in the UK Electrical Forum area at ElectriciansForums.net

Life and technology moves on, if FP had been about 40 years ago then the demise of MI would probably be old news now.
 
Hi, yeah as regards learning from ones mistakes, when I said to my friend, don't worry ive done that a few times, it's in context of working for @ 43 years and connecting probably millions of fittings.
Also not 2 circuits, as somebody suggested, I'm talking about 1 ring main. It's great to hear people remenicing about the days of dressing PYRO and making the ends off. Yes you could make a beautiful job with it. Does anybody know do you still make the ends off as was done @ 35 years ago?
I'm looking for solutions to a problem by the way, not for judgements on whether I should not have nicked a cable, or taken a friend's word that the upstairs sockets were off.
Thanks again for those with positive or funny remarks.
 
Did some MICC at college recently. I have a CITB book from the late 80's which I used for reference and the process and tools are the same.
I suppose with many decades the difference will be imperial sizes moved to metric and perhaps different materials for potting and insulating the bare conductors.
How is the cable damaged? If you just nicked the conductor with a machine screw can you not repair the insulation by replacing the sleeving (with the correct type)?
 
I can only think of two scenarios for the other sockets not working
1.It is not a ring and cable broken where nicked it.
2 it is a ring and it as above but there is another break in the ring now making not working after about 1/4 round after protective device.
