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

    Note the asbestos sticker on the DNO head, they are not going to work on it without throwing a bucket of water over it.


    From experience this will probably mean that a hole is dug outside the building, the supply cable cut and a new PVC cable run in from a joint to a new replacement head. Then a bucket of water can be thrown into the old head prior to it’s removal.


    So nothing is salvageable from outside to building onwards. It seems more sensible to install the new equipment and cables then swap them over in a day.


    I have not done that with more than seven flats and that was a busy day with metering services onsite as well as the DNO and myself, I was there until about half eight in the evening making the final connection as I could not finish until after everyone else had. Then metering services sent a lady the next day to ensure every flat was on the correct meter.

    Hi Andy, Cheers for your thoughts, Your correct on the Asbestos, there is a sticker on just about everything there! Most of it is for flash shields etc, they are all over the place. 


    Most of the meters here are in the individual flats which is good I suppose, that said unless there is 15+ on site there is not a hope in hell of doing a 1 day changeover.


    May look at getting a second supply tapped externally and removing the old one at the end... logistical challenges ahead. 



    Thanks
