10 ga cable will safely handle 12 A.

As I mentioned in your other thread I feel that a #10AWG may be too small to keep the voltage drop below 2%. Your system is at 18.9volts and 10.6 amps (2 panels wired in parallel). A #10 Awg can keep the VD at 2% for up to 15 feet distance. You may need bigger wire but it depends on how the CC works with the voltage it gets.
