Title: Include 690.35 Exception
Post by: Arvore on March 22, 2012, 04:03:24 PM
On page 92, first paragraph, the requirement that "one conductor of a 2-wire system...must be grounded if the maximum PV system voltage is over 50V (NEC 690.41)." It might be good to include the exception (690.35) here, as well. In all fairness, this exception is mentioned in the following page; however, it might be beneficial to mention the exception in context with 690.41. I think it would make it less confusing.
