I can't get to his web site now. I think we overloaded it. :)

So I can't see the details right now, but if the 50A unit means the cable rating is to 50A, then the maximum continuous charge draw would be 40A.

On the phone, we discussed how the Mach-E is able to handle up to 48A L2 charging. Based on that information, he said the 80A adapter is the one that is needed because it has thicker wiring.
The website states “To the best of our knowledge the adapter should be compatible with any vehicle that uses the J-1772 connector and protocols up to 12 KW.”

ClipperCreek thinks the Mach E charges at up to 10.5kW, the 48A charger will limit at 12kW of voltage is high (250V).

Well here is what happens when your connector gets a little bit too hot...

Ok I know you're curious what happened here? and what car is that?

This is the charge port on a Focus Electric (not mine, my coworker's at the time). The particular EVSE we use (the Bosch/SPX one--it did NOT cost me $1470!--in my garage pictures if you've seen them) is adjustable for different charge rates via a rotary switch inside. It was originally designed for the Volt and thus all the cables that shipped with it were spec'd to Volt charging currents (3kW if I remember correctly, and the setting inside was set accordingly).

Well the Focus Electric charges at 6kW and after a while the connector got a little too hot (he went through two sockets before determining it was the EVSE and not the car--he was lucky in that the Ford dealer warrantied both socket replacements). (The problem wasn't with the cable specifically, it was with the car plug.)

Once he figured out what was going on he called Bosch and they we're all "oops! here is a new cable". Apparently some time after that they had a recall where they shipped all owners of that particular EVSE new cables (yup I got a new cable too--apparently mine had the proper cable to start with since I never had the issue).

So yeah, you're going to want the proper adapter ;)

Aren’t most destination chargers set to something less than 48A/11.5kW anyway?

To use the Ford connected charging station 48amps, what is the minimum circuit it will run safely on? I'm guessing 60 and not 50?
60 Amp circuit is required.

I've seen some at hotels (via plugshare) that say they're rated for 16kw.

OK in an effort to keep you and @ChasingCoral safe, because I 💙 you guys, I just spoke with Dave at TeslaTap to get some clarifications. And by the way, you are free to call him, too. His cell phone number is listed at the top of each page on his web site. Very cool dude.

It is absolutely NOT safe to place an underrated TeslaTap adapter in between a high amperage EVSE and a high amperage vehicle. You will overheat the adapter and may cause fire or other issues.

TeslaTap DOES NOT IN ANY CIRCUMSTANCE negotiate charging speeds between EVSE and vehicle.

For safest connection to a Mustang Mach-E, you would need to purchase the 80A capable TeslaTap.

The circuitry in TeslaTap is there to send the 400 Hz signalling required by certain Tesla EVSEs in order to switch them into J1772 mode. The way it works in this case is that you must begin a charging session in this order:
  1. Connect Tesla EVSE to TeslaTap.
  2. TeslaTap is signalling with the EVSE to place EVSE into J1772 mode. Wait 26 seconds.
  3. While TeslaTap is still connected to the Tesla EVSE, you will now plug the other end of it into your vehicle. Charging should begin.
Some extra information that may be of interest to people:

Dave has gotten ahold of some Tesla Gen 3 Wall Connectors. These are able to charge at up to 11.5kW, 48A. He has recently figured out how to modify them to be J1772 chargers.

He's got about 10 more of these units that he'll be receiving soon. And in approximately a week, he will be updating his web site with a new offering which will be his modified Tesla Gen 3 Wall Connector where he's replaced the Tesla plug with a J1772 plug.

He has several Porsche Taycan owners interested in this, because he'll be able to sell it for roughly $629 while Porsche's similarly capable charger is a few grand.
Thanks for doing my homework for me! I was actually planning to just spend the extra for the 80A one just to be safe anyway, so this definitely confirms it.

Just wondering from your discussion with Dave, why the 80A unit.

The website states for the 50A unit: “To the best of our knowledge the adapter should be compatible with any vehicle that uses the J-1772 connector and protocols up to 12 KW.”

ClipperCreek thinks the Mach E charges at up to 10.5kW, the 48A charger can only charge at 12kW of voltage is high (250V). Since Ford has suggested the Ford Connected Charge Station charges the Mach E at the maximum possible, shouldn't the 50A be enough?

Unlike @timbop, I already ordered the 50A, prompting this discussion. I hate to go through the $90 cost of upgrading from the 50A to the 80A (added cost + $40 in two-way shipping) if I don't really need to upgrade.

Right -- this I do not understand, either. The conversation was moving really quickly... I had a hard time keeping up! He was pretty excited about the higher power charging for Taycans and the like.

I would definitely recommend contacting Dave to get further clarification on the 50A vs 80A.

The owner's manual is completely void of specifications on the built-in AC charger. :(

Thanks. I planned to call him.

My biggest disappointment with the version of the manual we have now is the lack of a specifications section to answer key questions like these. I realize EPA range is still TBD but I can't imagine the charging rate will change. They've given us the max 150kW on DCFC, what is it on L2? (rhetorical question to Ford, not you)

Well, it depends upon how he "rated" it for 50A. Is it #6 which can't do a sustained 8-10 hours of 50A, or is it #4 which can?

No Tesla destination chargers either. None. Tesla's need to charge at home or using a CHADEMO adaptor and find one of those.
I don't think you understand how Teslas charge with Level 2. Every Tesla comes with an adapter for plugging in a standard Level 2 J1772 charging plug. So they can charge at any level 2 charger anywhere. It's only if they want to charge at a Level 3 DCFC station that they would need to do it via a Chademo adapter (assuming there are no Tesla Supercharger stations).
