Fantastic detail, very much appreciated. I don't necessarily have a very long commute but do like the idea of being able to charge once a week overnight. Is there any downside to installing the pro? Proprietary for ford? more expensive/complex to install VS the NEMA?1) Depending on the wiring you can get up to 80 amps (19.2 kW) of power with the Ford Charging Station Pro, often referred to as FCSP or CSP. The Ford Mobile Charger maxes out at 32 amps (7.7 kW). You can decide how much charging capacity you need based on how you use your truck. Some feel the Mobile Charger is not as robust as the FCSP.
2) The Lightning has a bonded neutral. There's a lot written about this but the gist is you need a transfer switch that switches neutrals in addition to hot wires. This is an unusual setup unless you are are using a generator with a bonded neutral. For that reason, I suspect your setup will not work without modification. I installed a Generac 6852 Manual Transfer Switch. It has been written about here or other forums.
If you are running new wire, I suggest running the biggest circuit your panel can handle and using the FCSP. 100 amps is preferable. This gives you the option to charge relatively quickly overnight, which is the least expensive time to charge on many energy company plans.
