I rented an apt with a detached garage with an outlet specifically to charge my MY. It's been charging fine for 2/3 months now at 12/12 amps until last night when I got a random notification that my car stopped charging and my garage door was stuck closed. Since I don't have access to the breaker I had to contact maintenance. They sent me this email:

"We received the service request for your garage and maintenance has informed me that your garage’s breaker keeps tripping. Your garage is not working because you are using the outlet in your garage to charge your electric car. Those outlets are not wired to withstand that much energy. Also, the energy that you use from that outlet is charged as a community fee, which all residents end up paying every month."

Would reducing my amperage to 9 or 10 amps reasonably prevent the breaker from tripping in the future? I probably can't tell them to check their circuits since they are already not pleased that I'm charging my car. There's technically no rules/contracts and was never told of any limitations about my garage's outlets, so I would like to still trickle charge there as that was my initial intent ...but without having to stir the pot by having the breaker trip again.
