Hi Wrenches,
I’m preparing for 2014 NEC 690.12 Rapid Shutdown to hit in California January 2017. Specifically, I’m trying to determine what to do for new string inverter based installations. I’m assuming that microinverter, AC modules, and systems with power-level electronics (SolarEdge etc) are innately compliant. I spent a while researching SMA’s rapid shutdown system. It appears that we need five 16 or 18 AWG conductors for the control circuit. Any recommendations on what type of wire to use assuming we run it in our EMT run down from the roof to inverter? Tray Cable might work? Best, August August Goers Luminalt Energy Corporation m: 415.559.1525 o:415.641.4000 aug...@luminalt.com
