[about aluminum house wiring]
ISTR that the problem was mostly that electricians couldn't be bothered
to learn the new techniques and so on that were mandatory to install the
stuff safely.
If the wrong wire terminal combination is installed, then your house WILL
burn down, guaranteed! If you use the right CO/ALR fittings EVERYWHERE,
then over time you will STILL develop poor connections.
I've seen poor connections with copper wire, too; many industrial plants
are wired with heavy aluminum (I've done some of it). I don't know about CO/ALR
specifically, but there ARE effective ways to use aluminum wiring.
I don't know about all large plants, but the one I worked at would go
around every year to all the motor control centers and run an scan with
an infered camera to check for hot spots.
