The PV disconnecting means location requirement is that it must be readily accessible.

• A. accessible
• B. accessible to qualified persons
• C. readily accessible
• D. readily accessible to qualified persons

Answer: (C)

The important idea is that the PV disconnecting means must be able to be shut off quickly and without obstacles. “Readily accessible” means you can reach and operate the disconnect readily, without climbing, removing barriers, or going through locked doors or gates. This safety requirement ensures emergency responders and personnel can quickly de-energize the PV system when needed. That’s why the best choice is “readily accessible.” Saying it’s just “accessible” could hide potential delays or barriers that make it hard to reach promptly. Adding qualifiers like “to qualified persons” changes who is allowed to access it, which isn’t the intent of this location rule. Similarly, “readily accessible to qualified persons” would unnecessarily restrict access. In practice, the disconnect should be easy to reach for anyone who needs to operate it, not limited to a subset of people.
