Receptacle not compatible with Aluminium

[Knight511]

and what was the code he cited? the actual code number?

I'd fire this guy quicker than i could say abracadabra

I hit the reply button to ask that exact question, but I thought that would bring me from informed potential customer to the level of a know-it-all-***-hole..... I chose to not hire him instead. I bought the SER and THHN I needed to finish the job myself instead.

Meh. Thousands of homes in my area (built around 1970) are aluminum wired. My guess 99.8% are still standing and haven't burnt down.

Yes, insurance companies are still writing insurance on them. The local hardware stores/borgs still sell compatible outlets and switches.

My last house was all aluminum wire. I ended up pulling brand new copper to the high draw areas, doubling the number of circuts in the house, and putting the remaining aluminum runs on lower breakers... Not a perfect solution, but I was satisfied with my own safety. I everything I did was an upgrade because the "code" for the 70's was apparently so pitiful...

As I understand it, and I could be wrong, is that the wire of that era was soft and more recent wire is harder alloy.

Actually the opposite is true.
Before the alloy changed it was the same as the utilities used for overhead transmission lines which was designed more for long, straight runs rather than bending. It was stiff compared to the softer modern day stuff.

Yup

ACSR is used for power distribution and transmission. It uses Alloy AA-1350

Newer branch circuit aluminum wire is alloy AA-8000 used since 1972.... there are other alloys including AA-8030 and AA-8176
