There's no stopping me now.
I would hazard a guess at the UFO being a brown plaid lumberjack trapper hat.
Correct Watson. The black earthing conductor disappears into a black duct from which the underground supply emerges. P.N.B? I can't see how the earthing can be TNS as the supply to the intake room is by overheads for the majority of a very long run. I can't see a separate earth conductor. Perhaps I'm missing something.
It seems to be quite a small sized earth conductor for 400 Amp main fuses.
