Correct answer to question 10046
- D: 12.5 amperes
Explanation
The maximum current of a PV circuit is calculated as the sum of the parallel module short-circuit current ratings multiplied by 125 percent: 10 A x 1.25 = 12.5 A. The second 125 percent factor is applied later for conductor and OCPD sizing.
