[RE-wrenches] Enphase Nema 6 enclosure - not

[Kirk]

Connectors were fully engaged. I would also think what you described would cause an AC short, at least intermittently, in the connector. GFI tripping is a DC problem. It worked fine for 5 months until a week ago.

But if you don't rotate the cuff until the detant is engaged, you may not completely seal the connection by compressing the internal face gasket.

First, I noticed condensation in the led lens, then water literally dripped out of the AC side as soon as I disconnected it. This was mounted on the top backside of a panel, roughly two ft above a flat roof. ….. fascinating
