Paul, Sorry to spread things out like this, but the writing was really small. Dapo gave me some really good pics, though!. Cheers, mate!. Graham, could you please comment on these pics?.
Impressive—particularly for the generous red/green contact spacing. The plug slots must have taken some patience to mill, although pullout tension must have been significantly enhanced with wooden slots...certainly the soda-can contacts were useless in that regard.
It's hard to imagine how much time was spent putting it all together.
Australian/NZ and Argentinian sockets are mounted the same way,(earth below L/N) but on Argentinian sockets, the live and neutral are reversed in respect to Aus/NZ wiring.
Also, the Argentinian sockets have provision for 2pin 4MM dia. europlug type plugs as well.
Normally earth downward. (What'dya expect down under? )
Just how far out in the outback was this? I know supplies might be a little hard to come by if you're 300 miles from nothing, but they must get supplies in somehow from time to time. I'm sure it could have waited!
