    Yes. A OCPD of 600A between the tap and the busbar.

    Thanks.

    It would be best to do the line side tap and there are existing holes in the busbar to do so but he AHJ is asking for UL listing for it or have a UL listing engineer come do his field evaluation on it.

    On another note, I wanted to confirm the NEC2017 rapid shutdown code (I am so used to Solaredge and not having to worry about anything with it). If I have these string inverters within 5ft of the array that satisfies the rapid shutdown, correct? All the inverters on this job will be located at the arrays (groundmounts). Thanks again!

    If this install is in California then we're still on the 2014 NEC so that 5ft for rapid shutdown is fine until 2020. If on the 2017 NEC the rules change at the end of this year per special clause in the code.
