    Thank you Mike. I am afraid both electricians that installed and then inspected my circuit have no idea how to do this since they should have not do or ok a aluminum/copper circuit. I am afraid the first company which mostly does solar tried to cut costs with aluminum since panel is quite far from the garage and second did not know any better. I will need find somebody else  to do this job.  Not sure where you are located,  but let me know if you would know a knowledgeable person in Syracuse area. Although i started to understand this  better i do not feel comfortable doing this myself.

    I am a certified installer and have installed hundreds of gen2 and gen3 wall connectors.  A branch circuit with aluminum wire, especially spliced to copper, is not suitable for EV charging and may void your warranty.  For a gen3 set to charge at 48 amps, #6 copper MC cable or thhn in conduit are the minimum choices.  Continuous cable from breaker to TWC or from B to disconnect to TWC is the recommended strategy.  Compromise on these things and you're very likely to get the results you're getting.

    I did everything by myself except I had a now retired electrician do the hookup of my wires to the panel.  I watched and think I would do it myself now.

    Thank you Peter. Still waiting for Tesla to diagnose the problem with the WC. They might want the old one back if they replace it. I will let you know. The circuit seems ok per electrician now. BTW, who did you use to instal your gen 2 WC? Thank you.

    On a Gen 2, there is a reset button right on the wall connector.  If you have one on a Gen 3, I suggest you try that.  Also all the electric connections, including in the WC need to be tight per the specs.  And check the settings on the WC as to incoming power.  If your WC is truly dead, I would talk with you about buying it as I need one that doesn’t work.  I’m near you in Caz.

    I have been using a Gen 3 WC for 3 months on my nee M3DM and one night the circuit breaker tripped during scheduled charging. There was some  burned plastic smell in the basement where the panel is and the electrician found melted wires in a box connecting a long large gauge  aluminum cable running from the panel to a short 6 awg copper wire going to WC accros the all into the garage. He fixed the connection but now the WC is not functioning anymore- light goes steady blue- and waiting for tesla to see if they would replace per warranty. I got a second Tesla  electrician to look at the circuit and they say it is ok, but the box connection worries me. Not sure what happened. Any ideas? I am thinking to replace the entire circuit to 6 or even 4 awg  copper to prevent this issue.  Very happy with the car, but this is very frustrating and now have to charge using slow mobile connector.
