DNO Isolation of supply cable.
Former Community Member
After watching a YouTube video in which the DNO was moving the customers service head and they had to join the new cable to the old lead sheathed supply cable, I was wondering how the DNO isolates the old lead sheathed supply cable so they can connect the new cable to it?
I think that the short answer is that they don't isolate - the jointing is done live.
For a customer's recent service head move (from a site cabinet to the outbuilding which was built around it) the quote was for cutting the service cable and (having fitted a new service head) splicing it. In the event, it was possible to swing the service head around to its new position without cutting anything.
As far as I can gather, the DNOs will make a joint in the cable in preference to attaching a service head live.
If I am wrong, doubtless one of the DNOs in here will say so. ?
