Point of Connection Intent [RE-wrenches]

[William Miller]

<x-flowed>

Mark:

I have no history with the writing of this section, but in my humble 
opinion, the obvious reason for (B) (1) is so the feeders from the inverter 
have over-current protection and a way to turn off AC from the grid to that 
feeder.

As per your Question 2:  I did not write the section, but in reading it I 
see that it REQUIRES, not prevents  a dedicated disconnect.

Are you tapping the feeder to an existing disconnect that feeds another 
load?  If so, if it is otherwise legal and you provide another disconnect 
dedicated to the grid-tie system, you are correct.
