Re terminating ancient cables

Martyn
Hi Folks, 


So I may have a job in the offing where I will need to temporally re terminate these 3 cables, the one on the right is only 1m long so I’ll just replace it. 


The other two are rising mains from the 1940’s each feeding 20 flats, I believe them to be armoured PILC’s though happy to be corrected, the lead is being used as the earth. 


Has anyone re terminated similar and are there any pitfalls that may scupper me? 


The re termination will only be temporary whilst the new building network is being installed.89f8b92115c4d5d4e672a2d7771fc855-huge-a8ae4b2d-f17a-4e4e-a594-4469fa0801a0.jpg



Cheers

    If they are really lead clad, that is better news.

    Unless it is rubber covered wire clad in lead, which was not really used in that sort of size,  it will be waxed or oiled paper under the lead, which is actually very robust, so long as you do not kink it sharply where the cores come out of the lead sheath, nor wind it up,  or the ends have overheated and lost their 'greaseproofed paper' appearance.

    Section 3.1is the 'how to ' for safely opening up paper insulated lead clad. Note the use of binding with a wire or a hose clip to retain the cable integrity during cutting, and to give a clean end stop to the 'peeling' process.
