Simon,
In the top picture below the Ammeter, is that a Fuse Switch?.
When I started my time with the local PoCo here we were taking this sort of gear out.
What sort of single wires are those feeding the switch?.
In the third pic that I posted, I take it that there is a Busbar Chamber above them Fuse switches?.
Same picture, what type of cable is that leaving the third FS from the left?
Fourth picture, is it my eyesight or are those two bundles of cables different?
Same picture, is that a terminal block?.
In the second to last pic, the cables leving the Fuse-Switches look like TRS type cables, is this correct?.
If you have a good look at the bottom meter panel pic, it seems that the wires come out through un-bushed holes and you would be right in thinking that, because that's what is happening.
Wires were tough back then!.
BTW Simon, what does all of this gear feed?.
