Rapid shutdown requirements for PV systems are specified in which NEC section?

• A. 690.12
• B. 690.0
• C. 705.8
• D. 600.3

Answer: (A)

Rapid shutdown is a safety feature that minimizes shock hazards to anyone working around a PV array during an emergency. The NEC sets this requirement in the rapid shutdown provision for PV systems, which is Section 690.12. It mandates that once rapid shutdown is initiated, the PV system conductors must be de-energized to a safe, low voltage within 30 seconds at the boundary of the PV installation. This rapid reduction reduces the risk to firefighters and others approaching the roof or area around the array. Other NEC sections cover different aspects, such as how PV systems interconnect with the utility or general installation rules, which is why focusing on the rapid shutdown section is the correct choice.
