charging error message

[K_Dizzle]

Hey guys, I picked up my Tesla yesterday and I love it. I’m going to preface this by saying I know nothing about electrical work. I had an electrician install the 14-50 adaptor last week. When I plug my Model 3 in it automatically defaults to the max 32 AMP charge, but I get an error message shortly after saying that the cable is hot and that the charge rate will be reduced. It usually decreases to 8 amps. If I manually adjust the rate to 15 amps it will comfortably charge there. If I push it to 20 it gives me the error messages again after a few minutes and the amps decrease again. I’m really lost, but what steps should I take to trouble shoot this? Any help is much appreciated.

This usually means there is a voltage drop. This can be caused by a bad connection or wire which is too thin. I would ask the electrician to take a look again.

Try plugging into another source. You may have a problem with your 14-50 installation. Perhaps a lug was not tightened properly.

I tried a local charger and it’s accepting 30 amps without any interruption.

Have you felt the cable to see if the end near the car or the wall is actually getting hot? It could be a bad UMC or 14-50 adapter if it isn't caused by the 14-50 socket itself.

No I haven’t felt I’ll take a look this evening when I get in

Update as of 7:20pm. The electrician came by and we contacted Tesla charging support. Looks like the install was correct, they are now updating the software on the charger itself to see if it will solve the issue. I’ll keep you guys posted

Did you figure it out, any update? I am getting the same error.
