I am waiting for delivery of my new Y and had an electrician come out and install a 220v, 40 amp outlet (that’s all the juice I had left!) and want to make sure I got the correct adaptor. He installed a hook up that will only fit with the 50 amp extension. I went to Tesla and they matched the correct attachment, but it is the 59 amp connector. Will the charger know or will I be able to limit it to 40 amps max so I dint blow a fuse or do I need to get the 30 amp adaptor and have him install the correct wall outlet? I took a picture of both.
