Which risk increases when incorrectly sized arc-fault circuit interrupters (AFCIs) are installed in a residential solar photovoltaic (PV) system?

💡 Explanation

Nuisance tripping increases because tiny, harmless current fluctuations may be misinterpreted as dangerous arc faults due to the AFCI's sensitivity; therefore, the circuit breaker trips unnecessarily rather than correctly distinguishing real hazardous arcs.
