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

    One thing immediately struck me.. The cables outgoing to the cutouts have been re-taped with new colours, but my old mind immediately parsed it as white* phase, neutral, red phase, and blue phase (I'm slightly colourblind, not a good trait for an electrician, I know, i've heard all the jokes... and had parsed brown as 'red') Then I zoomed in and saw the link on 'blue phase' and went 'oh... white is grey... and... what a horrible mistake to make.


    * no I'm not THAT old, only in my 40s... but i've worked on some ancient installations and know the history of the yellow phase at one time being white. Even have some red-white-blue threecore in my museum (of that thread fame)... PE insulated and sheathed, and yes it's very flammable.. but less so than VIR or TRS.  And no earth.. (wasn't called a CPC back in them days!)
