aluminum doesn't conduct electricity as well as what, copper? Aluminum conducts electricity quite well. try touching a wire to an aluminum ladder while plugged into an outlet in the garage while you hold the ladder and see how well electricity is conducted through the aluminum!

Remember that older homes may still have some aluminum wiring instead of copper.


I don't think he said it "didn't" conduct electricity,
I believe he said it didn't conduct it "as well"... meaning
compared to other materials, such as steel or copper.
And he is exactly right. Aluminum does not conduct
electricity as well as the other materials...
Just because it was used in houses doesn't mean it does just
as good a job. It was done, because at the time, it was cheap.
In fact, in most all code now, aluminum is illegal to use
in residential wiring because it's too easy to over-heat.
