Re: [RE-wrenches] Flammable Vapor Ignition Resistant

[Jay via RE-wrenches]

What would be the rating for that? Is it a NEMA or?

The Enphase battery is sealed, but I don't know if that qualifies as sealed against vapor. I'd reach out to Enphase to get some guidance on that. It's always something with these AHJs.

Zeke --------------------------------- Seeking your suggestions and direction. My AHJ - after acknowledging that the Enphase 5p battery has a floor mount option - now insists that it must be 18-inches above the garage floor unless I can produce something that says it is "Flammable Vapor Ignition Resistant." We all know there is no open flame from an ESS and I know the 9540A depicts a battery at 6-inches. Anybody run into this and have suggestions on what I might show back to the AHJ?
