Aluminum wires?

[Philip J. Cavalcante]

Is this aluminum wiring?

Yea... Multi-strand is no concern... It's the solid from the 70's that you need to write up.

That looks like tin plated copper conductors not aluminum. They used a tin coating between the copper and the rubber because copper reacted with the rubber insulation. The conductor should have a R in it's type. Likely RHW.

I agree with Robert, tinned copper.

Copper clad stranded. Even actual alum solid for other than branch circuts is ok. Used here all the time for water heaters, A/c units. Stranded alum. is used these days for main feeds also.

The copper wire clip used on the 15 amp and 2o amp seperate breakers Might be a concern though.

Mark are you saying that this is copper clad aluminum?

I would still agree with Jim and Jeffery, tinned copper.
