Paul,
Just looking at the 3rd and 4th picture you posted above.
That's a rather strange way of connecting the tails to the overhead lines.
Usually we just put a line tap over the whole line and then slide the tail in and tighten.
Your method over there looks a lot neater though!.
Ian,
How many people live on the Isle of Mann?.
Must get cold there in the winter. BRRRR!.
