That may be because somebody decided to turn the TT into a DIY TNCS.
But as above. It doesn't matter if you have a job to do. Unless you really know what you are doing, (and with respect, you have demonstrated that you don't) what you have done is dangerous. There's nothing between the base of that old, shaky looking service head and the substation, maybe a 600A fuse there. Instant meltdown and ambulance if you get it wrong.
I understand that I would be shaking hands with the grid should I come in contact with that. I have industrial matting and gloves for just such an occasion.
I know this looks like I've just started willy nilly taking stuff apart and yes my inexperience shows but I can assure you that it was at least conducted safely.
Thank you to everyone who has pointed that out - I won't do it again
