Apologies for misreading the intent of your post.

No problem.

Is it possible hes vaguely telling you to match all breakers cause of the need for series rated system and not fully rated?

I love this forum for that reason: I had never really studied series rating. I’m reading about it now, thank you. I don’t think it applies in the case I mentioned (this was a 20A 240v backfeed on a 125a rated bus with a 100a main breaker).

Ev chargers are not a typical branch circuit though. It will usually require at least a cursory look at the calculated load on the feeder and service.

It seems like something that should be simple but we have experienced electricians here that it routinely baffles.

If they become more common, perhaps the fee will go down. But I would not bet on it.

In my experience 9 times out of 10 you pay for the cursory look at calculated load but you don't get it.
