Hi All -

I am having an issue with a tesla gen 3 charger that has been installed in a new residential home. The client brought their existing charger from their previous home and had it installed in their new home. The service on the home is a 400a service with (2) 200a Eaton BR series panels and breakers. Everything in the home works completely find until the tesla charger is connected to the vehicle. Once the charging process has started, every gfci/afci/dfci breaker in both panels eventually trips. The timing and order of the breakers tripping is completely random. Breakers trip in both panels, on both legs of the service. We have checked and re-checked all connections multiple times. I am not able to find anything that is causing this problem within the panels or wiring of the home. It seems to be a problem with either the charger or the vehicle itself...Has anyone seen this before?
