No GFCI required by the NEC for 240V receptacles, ask your electrician to cite a code section, won't find it in the NEC but would not discount the possibility of local amendments.
Apparently this is a brand new thing for nema 14-50s, it was mentioned by the first electrician I contacted before I decided to switch to the hard-wired and do it myself.

Not only that but the EVSE is basically a glorified GFCI circuit.
Yup, that’s why I switched to the hard-wired after hearing about the GFCI breaker requirement.

awesome price! I could be wrong, but I thought I read something about not hooking these up to GCFI breakers. Again, I could be wrong.
You’re right, that’s what the instructions say. But that’s the code requirement told to me by an electrician when I requested a quote. I will ask the inspector when they visit.

Maybe this has been addressed somewhere else in this thread or another, so I apologized if it has already been addressed. Is it possible to convert existing 120v outlet(s) over to 240v 14-50 NEMA? Maybe by using the incoming wiring from two 120v outlets to get you the 240v or something along those lines? I have a detached garage and one company has noted that they would likely need to have trenching through the back yard done from our breaker panel to the garage for an installation of a 240v 14-50 NEMA outlet. I have no problem sacrificing a couple of existing outlets in the garage to make for a single 14-50 NEMA outlet to charge my Mach E if that is something that can be done by an electrician.
As others said, that's not an option. One possibility (depending on your usage) is just to charge at 120V, but it's slow. The included charger appears to be 8A at 120V, adding about 3 miles per hour. But if you have an unused 20A circuit to the garage, you could get a 16A 120V charger to add about 6 miles per hour, if that were enough for your needs. But it's rare to have a totally unused 20A circuit. Couldn't be shared concurrently while charging. Although there might be an automated switch available, and the garage door opener often has a dedicated circuit.

Kinda of a last resort option, but a consideration if no other good choices.

No worries. I ended up shelling out about $1,300 to have a licensed electrician come out and trench my yard and run conduit to my detached garage and install a 14-50 NEMA outlet. Don't think I will be installing charging station at this point, but I will say that the $1,300 that this guy did it for came in much less than what I was quoted by a ouome other companies, so I am crossing my find gers that it all works when I get my MACH e home...

This charger is similar to Ford’s Connect hard wired charger in that it’s GFCI and putting in a GFCI breaker would confuse the charger and cause faults in circuitry shutting down the charger.

Are you going to claim the 30% federal tax credit for it? I suppose you can try even without buying the charger. But if not, then buying a charger in 2020 to make it all qualify for the credit basically pays for the charger.

No GFCI protection on 240 Volt recp required when installed in a dwelling.
Find it to be required anywhere in NEC. It is not in the code.

That’s IF the hard wired charger is NOT used!!! If a hard wired charger similar to Ford’s “Connect” charger is used, it already has GFCI circuitry onboard and using a GFCI breaker will confuse the circuitry and cause it to “fault” interrupting charging! Tell your electrician about this when he quotes code.
