This is a pic of the fuseboard on a property I looked at in Ballarat (105km NW of Melbourne) built 1975. Fuse boards like this (yes, literally, ceramic fuses screwed to a piece of board) are not uncommon on properties of this age, yet back in 1975 something like this in the UK would have been condemned
- IIRC Wylex CUs became the norm from around 1960.
At least the Bill and MEM units in the OP's pics had interlocks to stop you inadvertently touching live terminals.
