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
