Hello: I've got a JuiceBox 40 at home, plugged in to a NEMA 14-50 outlet with a 50A breaker @ 240V. The JuiceBox can do 40A @ 240V or 10kW. During charging of my Tesla, the J1772 handle gets extremely hot and melts the top right hole of the J1772-side of the adapter. The UMC side of the adapter is totally fine, no melting. Attached are some photos. Has anyone ever seen something like this? The handle is connected very securely to the adapter, it clicks into place with the handle lock. I have already blown through two adapters, so it cant be the adapter, can it? I contacted AutoChargers.ca in Canada who sells the JuiceBox and they have said that there is nothing wrong with the JuiceBox. I was told by a tesla employee that J1772 handles should have temp sensors on them so that they can turn done amperage in the event of overheating to prevent melting. Perhaps the sensor is damaged. Any insights?
