Yes that is correct and it was coated to make it easier to solder the joints .

Yes I am not concerned with the tinned wire but yes insulation is a concern . If in Doubt pass it on to, further evaluation by a qualified person. CYA
This was most commonly used in Knob and tube look close to see if there is any . Also did the panel have any over size breakers in it .
Good luck Call me if you need too . Royshomeinspection.com .

Many states and SOP’s have a requirement to report aluminum wiring present. How can you be sure of the difference in tin coated copper and AL ?

Never saw Wire rubber coated like this as aluminum.

That wiring predates the era of AL in residential applications (AL was expensive back then).
The rubber/cloth covering is also an indicator as to the age of the wiring.

Nope. I have never seen it other than in reference material, but it looks like copper (copper clad aluminum) and has an aluminum core.
Tin coated copper looks like aluminum with a copper core.

Looks like I am mistakenly reporting tin coated copper (TCC) as copper clad aluminum.(CCA)
Thanks for the description of the two.
Does anyone have any photos or information of the CCA.
Is the worn sheathing another way of identifying the TCC?
As far as I know there is no problems with either wiring I just want to make sure I am reporting the write material.
Thanks for your help

I think it is very unlikely you would be able to tell copper clad aluminum from ordinary copper without seeing a cut end. Remember it is aluminum coated with copper, so it appears to look just like copper. Copper clad aluminum is not a saftey hazard.
