Bought friday….backed out today….

wow… that’s funny. is there no building code dealing with such issues? did the engineer/architect not know any better? or did the contractor substitute the aluminum for copper to cut costs?

Vietnam war….shortage of copper ,and aluminum was cheap…..only widely used from 65 to 72…after that they made em use a bigger gauge….

I’m an architect. Dissimilar metals in direct contact with each other result in something called Galvanic Action…In simple terms, two dissimilar metals in the presence of moisture can cause one metal to corrode the other. For the technically minded, it’s the same process as electrolysis, and this tendency in metals is used to galvanize steel for protection.
It’s described in the codes, and is generally not recommended without adequate neutral separation, however specifications can vary.

if the code is lenient on the use of al wire, is the incidence of fire due to faulty/corroded al wiring low?

i hadn’t thought about this kind of thing, i’m glad this topic came up. for stuff like r/c cars, al wire was standard, but the life span of a battery pack or such was only a few months. al seat posts ‘sticking’ to steel bike frames is the worse problem. but for a home that you plan on living in, much less paying for for 30 years and not plan on being a fire trap…?
