What is the principal purpose of rapid shutdown for PV circuits on buildings?
- Reduce responder exposure to energized conductors
- BEliminate all equipment grounding
- CReplace array overcurrent protection for the renewable-energy system shown on the plans
- DIncrease daily energy production
Why A is correct
PV conductors can remain energized whenever illuminated. Rapid shutdown limits voltage in specified array and building zones to reduce hazards for emergency response and service work.
