New 240v outlet pulling 0 amps.

[UniversalDrago]

Hello,

I recently had an electrician install a nema 1450 receptacle on a 40 amp breaker for my mobile connector. When plugging in, the mobile connector shows the pulsating green light as if it’s charging, and the car itself says it’s charging but it’s pulling 0 amps. It is showing 240 volts, however.

When using the included nema 5-15 (regular US wall plug) adapter, it charged as it should.

It’s a weird issue, and I did schedule a service appointment with Tesla.

I did see 1 other thread where someone managed to get their 14-50 adapter replaced by Tesla and it did the trick, I’m really hoping that will work for me aswell.

Any ideas?

Thanks

Maybe it is your 14-50 adapter? I mean if your 5-15 adapter is working and charging then your 14-50 adapter is the problem.

There have been several reports of this same behavior with 14-50 adapters in recent weeks. It looks like there is a bad batch of 14-50 adapters out there.

Weird that you chose the exact same title...

New 240v outlet pulling 0 amps

Hello, I had an electrician friend come today and install a new 240v outlet in my garage. I went with him to Home Depot to purchase the supplies. We purchased some 6-3 wire, a 50a outlet, and a 50a two-pole breaker. After everything was set up and he left, I plugged in my mobile charge cable...

You are right, I replaced it at the service center today and it’s working as expected now. Thanks for the reply!

Why did you put a 14-50 on a 40a breaker?

I guess it will be ok using the mobile connector as it's limited to 32a. But do be careful if you use any other EVSE that would allow more.

Since I have a standard range model y, it can only charge max 32 amps. But yes, you are right. If I do get another EV that can charge at higher amperage then I will upgrade.

Just remember, you will probably need to upgrade the wire and breaker (not just the breaker).

The wire is rated for 50 amps. Home Depot worker told me it was a better idea. Thanks for the heads up though
