Adding in a D/P isolator BEFORE meter ???/

How are you safely isolating to change the CU then? I've heard any cabling from the meter backwards is the DNO's and from the meter onwards is ours.

I've been told by boss don't replace the old thin red/black DNO tails, just the meter-isolator-CU in 25mm tails per spec. Seems a waste of effort if the main incoming cables are poop.

50% of the time I have to move the meter down anyway to fit a metal skeleton board in, especially fitting a REC2 isolator. Helps to have a seal crimper
