@amy787 the hazard area is not sterilized airspace, because the chances of a RUD “are low” they are designed for aircraft to fly they at a perpendicular angles in order to minimize the risk. Once the event happens then it becomes a safety problem. Hazard areas have shrunk over the years
@spotted_model this is 100% an issue with their outlet wiring and not the charger. I also suggest the 3 prong tester. the fix is more complicated based on the wiring.
