What do you make of the branch wires? alum. or alum. coated copper? house was built mid-late 70’s. thanks for the input.
Its aluminum, tin coated copper has a fabric braided insulation and would be in older homes.
Wires appear to be Aluminum.
Aluminum Coated Copper?
i meant tin coated…i have aluminum on the brain so that’s what came out.
I am concerned at the sight of SOLID aluminum conductors on a 30A breaker, since the minimum for 30A is 8ga aluminum, and that ought to be stranded.
They used to make 8 gauge solid Aluminum wire, I’m not sure if they still do.
