Copper-Clad Aluminum Conductors

At the same dimensions, CCA is lighter than copper and has lower conductivity. A design that must match copper's resistance may need a larger cross-section, so the useful comparison is the finished conductor at the required electrical duty.

Copper content, core material, dimensions and temper determine the specification. Copper content must state its basis: mass, volume or cross-sectional area.

Terminations, temperature rise and corrosion exposure are part of the material decision. Test the proposed conductor and its connections in the intended assembly before changing an approved copper design. Where the governing specification requires copper, the material change also needs approval.
