I've found that car dealers generally know very little about the products that they sell.

Isn't that most sales associates? Their job is to sell, not educate. Surely most adults at this point in their life truly don't expect sales associates who push dozens of models to actually have real knowledge about them?

I purchased 4 vehicles last year and about the only thing they knew what to do was the fordpass app. TBF, I didn't really have any questions for them anyway given that with any purchase over $1k, the buyer should be performing their own due diligence. Especially since forums exist and people absolutely love to bitch nonstop about issues. On the F150 forum we get into rather complex topics like upgrading base trims to higher trims where there's a literal shitload of forks something can take. My XLT F150 has more options than any of the 'halo' trims do, even combos that don't exist like massaging raptor seats.

Do you operate the pharmacy out of the GTPE ? ?

okay i think we're starting to spin our wheels here, so to say! wait... can i not close a thread?

Nope. Has to go on endlessly.

The EVSE has a GFI internal for that purpose.

Ford’s installation instructions for a home charger recommends installing 50 amp GFCI breaker in the panel regardless of any protection built into the MME.

Also, the concern for water and electricity is that if there is an event and a person becomes part of the electrical circuit (gets a “nasty” shock), the presence of water changes the resistance in the bodywhich results in electrocution. This is why the NEC requires GFCIs anywhere near a water source in and outside of a home for electrical outlets. The GFCI will shut the circuit with the most minuscule of changes in resistance on the circuit.

That's all true, but if you put a device with built-in GFCI on a circuit with a GFCI breaker it can cause false trips. The Mobile charger doesn't have a GFCI built-in (thus the guidance), but most aftermarket EVSE do.

Also, as mentioned there is a circuit test that happens when you plug the EVSE in before full power is applied to the contacts. The contacts are not "always on" like an extension cord. When you press the latch button on the connector, power is immediately cut.

As mentioned in post 17, be sure the EVSE is UL listed if you want to be sure this feature is included.

The GFCI breaker protects against shocks when plugging/unplugging. The requirement to GFCI protect receptacle outlets rated over 20A started in the 2020 NEC. Many areas are still on older versions.

Every UL listed EVSE has built-in GFCI protection including the Mobile Charger. Cascading GFCIs doesn’t in itself cause tripping.
Appliances that trip GFCIs are either defective or incorporate surge protection circuitry that has leakage current to ground.

From this link here:

And on the mobile charger section of the same document it recommends a GFCI breaker without the same caveat

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'm really not interested in arguing semantics. This topic was argued about 2 years ago with Ford engineers supplying the information I repeated.

In this thread it was suggested that people should have a GFCI breaker, and I replied that the advice was contradictory to the EVSE manufacturers' guidance because GFCI breakers will cause issues. I supplied copies of that guidance AGAINST GFCI breakers from the first 2 manufacturers I thought of.

Fair enough?

All good.
Yes, there are issues, I agree.
It’s just that the EE in me gets irked when the cascading GFCI myth keeps getting propagated. I need to let it go.
