2020 NEC radio 690

This podcast is a reading from NEC Article 690 PV systems [Skip to the next podcast if the NEC is not your cup of tea]. Every 3 years the NEC comes out and I choose to pod-post it for you and my Heatspring Online PV classes. If you are not a technical PV person, you will find listening to this podcast exceptional for insomnia and becoming familiar with solar lingo. When I first read the NEC, I had no idea what it meant, but it did become familiar and was a step towards enlightenment.
