If im not mistaken, arent you supposed to have a 80 amp breaker for pro charger?

I believe it will support up to 100A. But not here, as I don’t have 80A of power available. My 400A service is pretty much maxed out at this point. So 60A breaker and 48A max charge it is.

You'd be mistaken.

I'd love to see that load calc

you talking over my head. You mean how I’m using up the 400A?

Yeah. The calculation the electrician did on your existing service to determine the max charge rate he could set you at.

In near every jurisdiction, it's part of the permit process.

I'd be amazed if your truly limited to 48A on a 400A service. (Also, might be a moot point if this is for a 2024 since it can't charge faster than 48A)

Dunno. I requested the largest possible breaker. They did an eval and came back with the 60.
My neighbor runs a large electrical contractor. I asked his opinion and he said ‘yeah you are pretty much maxed out.’

I’m not educated enough on all this to speak to it much more. There’s tons of electrical load here, i do know that.

Doesn’t matter. The maximum your 2024 can charge at is 48A. Your installation supports that so all is good.

Why is that, tell me about it. Sounds like you know everything

The FCSP is capable of 80 amps continuous on a 100 amp circuit & breaker combo.

But if there isn't a need for the full capacity ie. model year 2024 Lightnings, then it's perfectly normal to install for 48 amps continuous load on a 60 amp circuit & breaker.

I doubt your running 400 amps all at same time. I would of opt for 80amp breaker, change the wire to #4 awg and #8 awg ground.

if I’m limited to 48A then that would serve no purpose, right?

Yes, how? What are your big loads?
