The EV Transition Is Harder Than Anyone Thinks

How are you measuring your peak load? 200A is a lot. I could see getting a bit over 100A with all three ACs running simultaneously, but that leaves plenty left over for a normal L2 charger. Just time your charging so it's when you're sleeping, not cooking and doing laundry.

I only have one 5 ton AC, but I do have a pool, hot tub, and heavy draw electric appliances, and it takes some effort to clear 100A of simultaneous draw. Almost the only way to do it is to charge both my EVs simultaneously (and that's cheating, a bit, because the Tesla charger is pulling 48A all by itself).

Also, you could just dial it down, at 240V even 20A is quite sufficient for almost everyone.

But there's also passing inspection.

That's the problem - the city's inspection assumes full load from each of the appliances, plus some.

Why do you think that would fail inspection? A typical 200A panel has perhaps 400 amps of circuits on it. That's very normal. What primarily matters from a compliance/safety point of view is that the mains breaker is sized to protect the service wiring from overheating.
