Wave 4 invitation - did you get one??

You realize Pioneer74 is a Ford employee in Dearborn at the Rouge production line right? You know, the facility where these Lightnings are being manufactured? Also, no electrician is going to install the necessary equipment against recommendations of Ford or Sunrun because their butts would be on the line as well…Oh and nice plug about the cost of your house. Really impressive man.

And funny that you mention people doing things without thinking about potential future consequences. In addition to considering those, I also like to post with up to date, knowledgeable, and accurate information.

Respectfully, you are wrong. No electrician is going to care what is in some sunrun brochure says if they even read it. They are going to care what the electric code says. Requiring more then a 200 amp service would never be applicable for a charger pulling power to charge the car. Never would more power off the pole be needed. A higher amp panel would only be needed if the car is able to feed back in to house while house is still hooked up street (like a tesla power wall or solar install).

Close . . .

Depending upon the jurisdiction, the electrician will need to pull the relevant permits from the city/town/county building department. Even if not required (it is required in my county), the electrician should do a detailed electrical load calculation to make sure that the panel can support the 80-amp charger. In my case, it should not be a problem since we have gas heat, gas cooking, gas water heater and a gas dryer. Had this been an all electric house (or even if we had an electric cloths dryer), we would not have enough capacity on our 200 amp panel to support the 80-amp charger. And, to be clear, we are not planning to provide electric service to the house from the Lightning in case of a power failure.

You have to look at the totality of the circumstances for each application because you cannot assume that all homes with 200-amp service will have sufficient capacity to allow the use of an 80-amp charging station.

I agree with you on that statement, if you are very heavy electric a load-calc could push you into a bigger service. you are 100% correct here. I would make the case that most users would just de-rate the charger or do their charging overnight when load in rest of house is less. My intended point was more that nothing would require 320 amps service as a blanket statement and the original 320amps was almost certainly related to a setup like grid tied solar or power wall.

I understand. In my County, the code official assumes a worse case scenario for the calculation, not a circumstance where charging is done after hours when appliances are not in use.
