PV equipment installed on detached structures, such as carports, are subject to which requirements regarding rapid shutdown?

The correct answer is that PV equipment installed on detached structures, such as carports, are exempt from the rapid shutdown requirements outlined in Article 690.12 of the National Electrical Code (NEC). This is because the rapid shutdown provisions were primarily designed to enhance safety for emergency responders and are specifically related to PV systems installed on buildings. Detached structures do not fall under the same critical safety considerations as those installed on traditional rooftops, where access by emergency personnel may be more complicated.

This exemption is important as it streamlines the installation of solar power systems in detached structures, reducing unnecessary complications and costs associated with compliance to rapid shutdown requirements that primarily pertain to building-integrated solar systems. Understanding this distinction is crucial for effectively navigating the NEC and for ensuring that installations are both compliant and safe.
