The 16th edition sticky tape appeared after the doorlock fell apart ....... its been replaced now .
We did a Saturday / Sunday upgrading that , everything onsite on Friday .......Network booked in for Monday morn , none of those old sub-mains reached their new MCCBs so a boxfull of metric crimp lugs to fit onto imperial cables ....some were a bit oversize TBH but they've all been fine ever since. Couple of the old conduit ones are in VIR (Or as some say these days VRI) cable still in use , still in good condition .
A later pic ( new lock fitted) shame that customer was to box-in the mess of cables & conduits above but never did. All forgotten once power is restored.
