Testing home charger without car?

[Kohlzor]

Hey folks,
We are getting our model Y next week but our Electrican is installing the home charger in our garage this week. Is there an easy way to test the home charger without the car? Hard to get hold of contractors these days so want to make sure it works as expected. Electrican will be installing it on a 80amp breaker.

Not really, ask someone you know that owns a Tesla to come by and buy him/her a beer/coffee afterwards.

See if you can rent one.

80 is a lot. But it gives you future upgrade possibilities.

Surely, there is someone you might know that has a Tesla, and can test your new setup to the 40 amp charging limit (is 40? still on L2? correct me if I'm wrong). Like the second poster mentioned, a brewski and a free charge for an hour or so will let you know it is working. And I should add, I need to do this myself when a workmate gets her 3 next month - though my charger is limited to 32 amp on its 40a 240v circuit.

Overnight test drive.. thats what i did

The wall connector is nothing more than a glorified junction box except for some tell tale led lights. Everything regarding charging is controlled through the car.

You can check the wall connector using its setup procedure. There’s a URL that you go to to set it up (standard locally hosted on the WC just for setup) and it will give you the details of the wall connector.

But I just asked a friend with a Tesla to come over and make sure it all worked. If you’re getting the new gen 3 charger, it’s limited to 48 amps, FYI.

You should check; If you purchased, having the electrician install the current Gen3 Wall Connector the maximum circuit/circuit breaker allowed is 60A. Installing the Gen3 Wall Connector on an circuit with an 80A circuit breaker is incorrect and a code violation. (Note: The older Gen2 Wall Connector could be installed on an 80A circuit.) If the electrician is installing a sub panel, the sub panel could have an 80A circuit breaker, the Gen3 Wall Connector would have it's own circuit breaker not to exceed 60A.)

On top of that an 80 amp breaker would require a larger size than 4 gauge which will not fit into the wall connector terminal lugs assuming it is a gen 3. Max is 4 gauge.

Ah didn’t know this.. they were running a wire capable of 80A to the garage to a disconnect will need to check with them to ensure they install a 60A breaker.

Not that it means anything any longer, but one of our referral users reached out to us the other day and ask if we can come by and check their install. They're not far. If you wasn't all the way up in snow Country, I'd come by.

Easy to test. Turn power off then on.
If all five green lights light up, it works fine.
It’s all in the manual. I installed mine a few weeks ago.
You should also set up its wifi. It will tell you what the voltage and amperage read is.

 

[Kohlzor]

Thanks for all the recommendations. Charger is installed on a 60A breaker. See 5 green lights when turned on.

48 amp on MY LR, 32 amp on model 3 SR.
