Installing a transformer in my truck

[Mustang11s]

Just use one of these cords. Gives you 2 30amp 120v legs with 2 outlets per leg. Keep one in my frunk.

I want to know how you got that gorgeous background on your dash screen!

You mean the dust?

You've definitely getting that Lightning to work for you. I wonder if this adapter off the L14-30 would slow the trip while handling the startup current?

That adapter still only uses 1 leg of the inverter

Am I the only one hoping I would see a Lightning turning into Optimus Prime by clicking on this post?

Guilty!

I think it would still power your mixer. The 120V would be fed thru a 30A breaker instead of a 20.

actually, it shows that 2 of the 120v 20amp outlets are on one 'leg' of the 240v output(black wire), and the other two on the other 'leg'(red wire).... so, any of the outlets could potentially receive up to the full 30amps of 120v 'leg' of power... the breaker of the truck(30amp) determines the max draw, even if the outlets, themselves, are only '20amp' style outlets...

I have pulled 28 amps for several hours on one leg through the 30amp plug. No problem.

Interesting. I figured as conservative as Ford seems to be, that they would limit the 120V receptacles to 20A, either with a circuit breaker or software.

It doesn't trip the 20.amp breaker. breakers are designed to be tripped by heat. The inverter has 0 overload so for a split second I bet it pulls 5 to 6000 watts and the inverter can't handle it. It's a high frequency inverter not low. So it's mossfet based not transformer. Which means it sucks for inductive loads

Was it an inductive load. Probably not did it have a surge of 5-10,000 watts so 40 to 80amp surge doubt it.

I hope you don’t have a 40-80 amp surge on a 20amp 120v plug. Sounds like you need to fix your equipment. I was running a 50 amp plug fifth wheel with 2 A/C units and an electric water heater. Pulling 38 amps on one leg and 18-28 on the other. Both A/c units would cycle fine. Even ran the Air fryer with the water heater off. While the A/C units were running.

Modern breakers are thermo-magnetic. Magnetic for instantaneous high current, and thermal for sustained overloads. I have no idea what Ford is using.

right, and these are not the typical 'breaker' we are used to seeing in our camper or home, they are 'resettable' breakers, maybe even more like 'switches'... they may be able to 'read' amperage, versus having to 'wait' for heat to come into play...

Not having investigated how Ford has this implemented, it could all be done in software. IDK

One other option could be a hard start capacitor on your mixer to avoid the transformer (assuming the draw once running is reasonable and should be below 20 amps given your plug). I used this on my home AC condenser/compressor unit as it was popping a breaker on the inverter/battery backup system. This solved that problem and is actually much better for the motor as voltage stays higher and you do not get as much instantaneous current draw.
