CCA Round Wire and Copper Wire
For a round-wire comparison, set the required resistance and length first. Calculate the diameter and conductor mass for each material, then check the terminal, insulation and winding or stranding process. Include the required copper proportion for the CCA option.

| Decision | CCA round wire | copper wire | Acceptance basis | Your input or result |
|---|---|---|---|---|
| Conductor structure | Aluminum core with copper cladding | Single copper grade and temper | Record copper ratio by mass or volume and metal diameter. | |
| Electrical basis | Select section against measured composite resistance | Select section against copper-grade resistance | Compare the same length, test temperature and resistance target rather than equal diameter alone. | |
| Termination | Check cladding, exposed ends and approved terminal fit | Check copper condition and terminal fit | Test pull-out and contact resistance with the intended crimp or solder process. | |
| Specification | B566 context applies to bare round CCA wire when the construction meets its scope | Use a copper round-wire purchase specification for the grade and condition | A standard reference is not stock, finished-cable qualification or permission to substitute. |
