[RE-wrenches] Disconnects for "ungrounded" arrays

[Howie Michaelson]

Hi Guys,
I seem to recall hearing at a workshop maybe 18 months ago, that NEC 2020
was changing the string disconnect requirements for ungrounded arrays,
changing from the need to break both the positive and negative legs of a
string, to just one leg.  This might have been specific to strings with
optimizers, but now I cannot find my notes on this topic.  Am I just
wishful thinking here?
Thanks,
Howie
