I believe you need a GFI transfer switch to avoid the ground fault tripping in the F-150 Lightning 240v/30A outlets which apparently are GFCI protected.

Most GFCI's found on portable generators are there to protect the 15/20A, 120-volt outlets, and not the 120/240 outlets that are used to connect to home transfer switches.

However, you need a GFI transfer switch to connect any generator (like to F-150 Lightning) to your home if the generator 120/240-volt outlets are GFCI protected - without a GFI transfer switch it creates a ground loop and trips the circuit.

I would have the same issue in my home I believe because I do not think my manual transfer switch that I use for my gas generator (use rarely) is a GFI transfer switch.

For the source of this info, see: https://www.electricgeneratorsdirec...ipping-a-Generator-With-a-Bonded-Neutral.html

I believe they are who I bought my equipment from years ago.

An example of a GFI transfer switch: https://www.wincogenerator.com/product/reliance-manual-transfer-switch/
@chl I followed what you said here, and thanks for the great write up. I already purchased a Generac 6853 since that seemed to be the hot product. However, I have not opened it yet as I am still waiting on the FCPS and installation. Some people seem have it working by making sure the plug inlet and switch are not bonded. Do you think this is the wrong product and a GFI specific transfer switch is better?

Thanks!

As a test I was able to get the truck to power the house using a L14 30 amp 240v cord and a L14 30 amp generator inlet box. The outlet and outlet box are grounded to the truck and the ground in 10/3 wire coming from the panel is left disconnected in the outlet box. the hots and neutral from the panel are connected to the outlet box like normal.

I downloaded the User Manual, and searched for "bonded" in the text and I found this:

On page 11 of the user manual it states:

"Requirements
The Upgradeable Manual Transfer Switch is designed for use with portable generators with a bonded neutral, and used as a separately derived system. A grounding system and a grounding electrode system shall be connected to the ground terminal on the portable generator."

Also if you look at the wiring diagram on page 18, it shows that the transfer switch DOES switch the neutral lines isolating the bonded panel neutral from the generator.

Both are attached for your reference.

So is sounds like it should work.

Same! But installed by an electrician. Works great and pretty decent cost.
