We have just released the long awaited 2023 NEC class on HeatSpring. We spent more time making this class than any other class, so I am sure you will love it. We have Sean White and Bill Brooks going over many of the fun details and Code changes in this course. You can learn more here and some of the lessons are free samples.   www.heatspring.com/classrooms/30-hour-2023-nec-pv-energy-storage-building-and-fire-codes/active   690 Part VI is a shorter Part of Article 690 and the end of 690 was dramatically reduced and rearranged in the 2023 version of the NEC.   Here are some of the topics covered:   690.56 Identification of Power Sources 690.59 Connection to Other Sources 690.72 Self-Regulated PV Charge Control (neat silicon science here)   This podcast is mostly a reading from the 3rd Edition of PV and the NEC by Sean White and Bill Brooks.
