Q... all I said was that they could have run a cable from the control centre main panel to the point of connection and had it ready for use when they completed the 1.5km feed rather than waiting until after the feed was in place.

As for perhaps not knowing if the exising control centre primary supply circuit was u/s until the 1.5km feed was in place, someone should have checked the continuity long before that.

Of course, I never did mess much with electricity... it's too sneaky... ya can't see it! Oh, when I was a lad, I used to drag my feet over the carpet and touch my brother's ear lobe. Same with rubbing a baloon on my hair... not much chance of that now.
