I have been installing AL for more than 30 years. There is nothing wrong
with the wire. The problems come from the installers and the terminations.
If properly terminated there will be no more problems with AL than copper. I
do not know of any utilities that use copper any more. All of the long lines
and distribution lines in the West are primarily AL. If they were not some
maroon would steal them. Which has happened in the old days, 1960-70's. All
of that wire was replaced with AL.
Your home and mine (also built in 1971) have lasted this long. Chances are
they will last a lot more. This is my 3 home of this vintage.
Do you know anyone with a 1000 volt meggar? You will need to unplug
EVERYTHING for the test. The meggar can tell you if there is an insulation
problem and to a point loose connections.
Most of the published articles are done by fire departments and the copper
association. Unfortunately the fire department only gets to visit when there
is a problem.
Ideal makes a wire nut for AL-CU connections. About $2 ea at the box
stores. Devices should be listed AL-CU and they are harder and harder to
find.
