None of the AHJ's I work with would accept that much ambiguity on a planset submitted for permitting for a commercial PV system. I have even had a design kicked back because I didn't specify exactly how I was going to implement a line side interconnection.I can understand that. But I see a lot of sealed drawings where the circuit terminates at an existing bus or something with a note to the effect that, "Contractor to install in compliance with codes and equipment manufacturer's requirements." No details were provided. So many, and on all size systems.
I wish more AHJs were like that. I see way too much left to the imagination of the contractor. But on the other hand, in most of the systems I work with the landing is a basic lug connection to the busbar in a large SWBD. Maybe a bus flag is used. So the detail is simple and generic. There is no significant modification to the equipment and it all tends to get a NRTL field certification.None of the AHJ's I work with would accept that much ambiguity on a planset submitted for permitting for a commercial PV system.

one question here, if thats a feed through connection it still have to be on the opposite end of msd and still should follow 120 percent rule.My guess would be feed through lugs from the note. But it does leave the details to the contractor.
Yes and yes, or rather, 705.12 has to complied with, however you qualify the bus.one question here, if thats a feed through connection it still have to be on the opposite end of msd and still should follow 120 percent rule.
