Paul,
Just a short note on aluminium wiring,
I was recently talking to a sparkie who done
his time in the UK during the 1960's and he reckoned that someone over there must have had an aluminium fetish, as he was saying that all of the cables, conduit and a few other things were all manufactured from good
old Al,is some of this wiring still found in older installations?,the aluminium conduit must have been a shocker to work with, ever tried to straighten a bent length
of aluminium?.
