Wall charger circuit breaker size and plug size

[Brissienew]

I remember reading about this but can no longer find the thread, hoping that someone can give me a quick answer. What is the correct size circuit breaker for a 3 phase installation of a model 3 wall charger? Also what rating for the 3 phase plug and socket? The manual states 32A per phase. I contacted an electrician who asked me to send him a link of the manual, which I just did. Thanks

IIRC you need a 40A breaker to support a 32A High Power Wall Connector as it’s considered a continuous draw so the 80% rule applies.

Mine put in a 32A RCBO. He said it has some "margin of error" built in ¯\_(ツ)_/¯
It's been ok so far anyway, the car sustains 32A for hours.

Yep. My electrician said 32 amps per phase breaker. That’s what he installed. No issues. I draw 22kw.

There is no specific answer, as it depends on your installation. Let the electrician do their job. Give them the specification of the plug and some money.
