Craig,

 

This one is easy to misinterpret. You missed the words “live parts”. This has been removed from the 2017 NEC because it is actually referring to load circuits being fed directly by a PV system on the dc side. All references to loads and batteries are being removed from 690.

 

This is a complete non-issue.

 

Bill.

How is everyone handling 690.7 (D)

Circuits over 150 Volts to Ground. In one- and two- family dwellings, live parts in photovoltaic source circuits and photovoltaic output circuits over 150 volts to ground shall not be accessible to other than qualified persons while energized. 



If you have a commercial (non one or two-family dwelling) are you screening your ground mount arrays to keep people from touching live conductors PV wires)?

Thanks for your thoughts
