Charging in Rain/Snow

It does NOT give the reason for nuisance tripping as its internal GFCI. Because it’s not the reason.

That sentence is telling us two things:
1) Don't use a GFCI breaker due to nuisance tripping.
2) Don’t worry, because the EVSE provides GFCI protection (like all UL listed EVSEs).

I believe it's the way certain capacitors charge. "missing" return current that a cap is eating due to circuit design is notorious for tripping AFI, which operates similar to GFI. Anyone with AFI breakers can attest to nuisance trips when plugging in certain DC consuming electronics (or using a large motor, or if you're just talking trash about the breakers) will cause a nuisance trip.

Someone that's inattentive may plug in their car and think it's charging only to come out the next morning to see it's still got the same or less charge than when they plugged it in. That could be a bad situation if you needed more energy for the day than was contained in the battery. Sure it's the breaker's fault, but they're probably calling ford after taking to social media.

It isn’t just the initial charge, caps continuously conduct AC. When they’re deployed in surge protection circuitry, connected between line and ground, it causes problems.

AFCIs are whole different kettle of fish beyond the scope of this discussion.

Dave, some manufacturer's use MOV's in there systems to clamp overvoltage. And they do it to ground with 230 volt systems.
