Hello Everyone - first time posting, long time viewer here. Thanks to all in this forum for great insight over the years.
I'm looking to install an aluminum critter guard around the perimeter of some rooftop PV systems, attached to the module frames in a non-bonded manner, and I'm trying to sort out equipment grounding requirements. I was surprised to see this conversation hasn't started on this forum, as I know these solutions have been installed for a few years now, though maybe I haven't looked hard enough. When looking at NEC 250.110:
“exposed normally non-current-carrying metal parts of fixed equipment supplied by or enclosing conductors or components likely to become energized shall be connected to an equipment-grounding conductor (EGC)…”
How does this group feel about the likelihood of an aluminum barrier (similar to a gutter guard/fence) being energized?
How would you answer if the critter guard was coated with PVC, or some other non-conductive material?
Has anyone had a code enforcement official weigh in on this yet?
Seeking your valuable opinions on this topic before moving forward with the solution.
Thanks!
