*Subject:* [RE-wrenches] Guarding against live parts 690.7 (D)
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
