As a Home Inspector, I get to see all sorts of wiring issues with all type of wires, including Knob-n-tube, cloth wrapped, Aluminum, AC used in wet locations, undersized copper and much more. There seems to be a LOT of misleading information on CCA wires, and I would like a clarification. We, as an industry, we taught that you needed to +1 the gauge of the wire going from copper to aluminum for a given ampacity. Because it takes a 12ga AL wire to carry a 15A load, we should NEVER see 14ga Al in a residential application.

Is the Same true for CCA?
so 12ga for 15A, 10ga for 20A and 8ga for 30A??

How can you identify CCA quickly? A lot (not all) of Aluminum NM wire had a blue sheath, was there anything similar for CCA wire? Again, thinking as a Home Inspector, how can you identify the wire as CCA quickly if you can’t see the type on the cables (faded or turned away) or the cut ends of the wires, which may be hard to see anyway.
