So after playing with the included cahrger and car settings, I can't find a way to adjust amps.

The plugs that are included in the car are 240 14-50 and a tradition 120 plug.

I have a DryerBuddy that is connected to my dryer outlet that was shared between dryer and My model 3. I since then gotten a dedicated Tesla Wall connector for my model 3 and planned on using dryer buddy for the Mach E charging.

Problem is that When I connect the Ford charger, it charges at sustained amps of 30. Dryerbuddy has a LED screen showing how much amps it is pulling. I believe on a dryer plug and wiring, you only want a sustained 24 amps.

In my Tesla, I can go into the Car menu and select any amps I want. For example, I can plug the car to a 50amp wire and select to charge at 24 amps if I want. Thats what I was doing. My Model 3 also came with a 14-50 plug, plugged it to my dryer buddy and adjusted the car settings to only pull 24 amps. If pulled the full amps from a 14-50 plug, then my breaker will obviously trip because I dont have the correct wire for the load.

So I cant find a setting to adjust amps and can't use the included 14-50 amps for now. Stuck using the 120 plug for now until i find a solution. Any tips ideas would be appreciated.

Would be a nice OTA update to add a feature where you could select your charging rate, when you don't need as fast as possible. My spouse always set her MB to it's near slowest rate when she was at work all day and chargers were readily available.

Is there a way to adjust amp limit for 120V?

I would have gotten a standard J1772 EVSE instead. J1772-to-Tesla is easy, $50 OEM part. Tesla-to-J1772 requires one of those TeslaTap: they are expensive and not UL certified. As a result, I just don't see a reason to get a Tesla EVSE.

I'd say, replacing your Tesla EVSE with a J1772 EVSE is the best way to go, if it's not too late to return the Tesla EVSE. You can then use the J1772 EVSE for Mach E, and mobile charger (Mach E's or Tesla's) plugged into the dryer socket for your Tesla.

So I cant find a setting to adjust amps and can't use the included 14-50 amps for now.
I don't believe Mach E lets your configure that. I remember reading it somewhere on this forum.

Assuming it's too late to return the Tesla EVSE:
  • You can wait for OTA, but no one knows when or whether that will be available.
  • You can buy a 2nd EVSE that allows you to configure the maximum amperage on the EVSE side.
  • You can use a TeslaTap to charge your Mach E off your Tesla EVSE, and charge your Tesla with mobile charger (Mach E's or Tesla's) plugged into the dryer socket.

I bought the Tesla wall connector a year ago and wife planned on maybe getting the model Y. But we both fell in love with the Mach e. plus the Tesla one looks so damn good in my garage. Not getting rid of it.

I’ll probably end up buying a 2nd evse for her Mach e that allows me to set Amps as other in this thread mentioned.

I did send a note to the ford evteam to that effect so maybe you can do the same and we can have that capability through an OTA. For the time being I'm sorry but you are right there's only the 120 solution.

So I bought a Splitvolt to try out and see I can do 240v charging instead of the 110v. It seems like it works, but the LCD monitor says it's pulling 29A, even though there's supposed to be a 25A circuit breaker integrated.

What's the concern about drawing power at 29A? Fire? I know the 80% rule should be 24A, so I'm not sure if the integrated circuit breaker is broken or if the monitor is giving me the wrong data.

In the Bay Area, I found that you can sign up to charge at some schools for about 10¢/kWh, which is much cheaper than charging at home. I'll probably return this and my 50' extension cable until I find a need to charge at home.

Also, I looked at my circuit breaker and it looks like my dryer had 2x 30A breakers tied together, which doesn't seem quite right...

You‘re likely seeing a 2-pole breaker. That’s how 240v breakers work. It’s two 120v breakers tied together. Completely normal.
