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

    . . . they have declared they have no asbestos trained staff so will refuse to maintain it themselves. . . 




    The best option with asbestos containing cutouts is replacement, depending on their condition. Often this means de-energisation by cutting the cable outside the building, then cutting of all cables entering the cutout, followed by its removal from the wall without opening, double bagged, then disposed of. The risks of releasing asbestos fibres by attempting maintenance is just too high. 


    Regars,


    Alan.

    100% Alan, I just wish they had a form of communication that was better than one reply to a tenth of an email every two weeks!  


    Infuriating dealing with such incompetence!

    Certainly the bit of SSE round here (as DNO) do exactly that, and quite promptly, so at most they mean 'no-one local'.

    Interesting internal photos, - be aware while it is open that there may be hairy asbestos pads under the ceramics, even though the rest looks benign.

      I have not seen quite that  live screw 'wedge-lock' arrangement before, but I can imagine it is possible  to over tighten to the point that just turning the screw the other way does not move the wedge out. Int rather depends if the bolt is threaded into the wedge and pulls on the flat, or is threaded into the flat and pushes on the wedge. In any case, while fascinating it is not yours to play with and really SSE should be planning its replacement.

    I presume your Emails already start with Subject  Defective Cast Iron Cut-out Replacement. to get them in  the right mood.

    The fotos of the old installation with the green DNO cutout are very interesting old gear is certainly more interesting to look at than the new stuff. I wonder if the 2 meters shown are still accurate presumably one is volts the other amps did you try the amps one? It looks like the earthing has been upgraded a bit in recent years  too
