I think the issue is GFCI breaker trips caused by the grounding tests that EVSEs are supposed to perform.I respectfully disagree with this. Every hair dryer has a GFCI on the plug and every bathroom receptacle installed per code since 1979 is GFCI protected. They don't cause each other to trip.
The technical explanation: a GFCI measures the current in the conductors. If the difference is greater than a preset value (normally 3ma) it means the difference is flowing to ground instead of where it's supposed to and trips. A second GFCI on a circuit will not cause this current imbalance unless it's faulty.
