Question 10048 of 1003 · California General Electrician Exam

A PV string has modules with an Isc of 8 amperes. What minimum OCPD rating is required if the circuit needs overcurrent protection, using both 125 percent factors and the next standard size?

Exactly one answer is correct.

Show solution

Correct answer to question 10048

  • A: 15 amperes

Explanation

Maximum current is 8 A x 1.25 = 10 A, and the OCPD must be rated at least 125 percent of that, which gives 12.5 A. The next standard OCPD size above 12.5 A is 15 A.
