Yes, the wall charger should be 80% of the breaker.I had an electrician install the wall connector and he put in a 50-amp breaker but set the charger to charge at 60A. Is that a hazard? Can I buy a 60A breaker and swap it out? Or is there more to it?
You don't replace a breaker with a larger one without checking the wire size.I had an electrician install the wall connector and he put in a 50-amp breaker but set the charger to charge at 60A. Is that a hazard? Can I buy a 60A breaker and swap it out? Or is there more to it?

Is this a big deal? I have no knowledge of electrical matters.I'm absolutely amazed at how often this happens. In my experience it's almost ~50% of installs....
Really? This is that big of a deal?It should not be your job to fix his install. If the wire is rated for 60 amps, he should come out and replace the breaker free. If it is NOT rated for 60 amps(48 continuous), you should recommission the HPWC to correspond to a 50 amp breaker(40 amps continuous)
A 60 amp breaker would be okay for 4AWG in NM-B(sheathed) wire, or 6AWG in individual wires in conduit(these are for copper conductors).
I'm not sure I'd trust the electrician any more. I certainly wouldn't be requesting his services on another job.
Will it burn your house down... no . The breaker might trip due to overheating, especially if there are other nearby breakers moving lots of current or the ambient temperature gets high.Is this a big deal? I have no knowledge of electrical matters.

So this time you got lucky.. the breaker he installed may be appropriate for the wire he installed. What happens the next time when you aren't lucky, and he puts a 50 amp breaker on #10 because that's what he had on the truck. For that matter, we actually don't know what he installed for your HPWC. If its less than #6, your house is definitely in danger. (Less than means #8 or #10, in this case.)Really? This is that big of a deal?
Holy cow. Also, totally cool that you work at a nuclear facility. I hope we can make a huge switch into nuclear energy soon.I don't know how big of a deal it is since there's so much margin built into wire ratings. When they installed the chargers where I worked they put 40A chargers on a 40A circuit instead of a 50A circuit so the breaker kept tripping. And these were electricians working at a nuclear facility. Supposedly the best of the best. Just amazing how often this happens. How hard is it to divide a number by 0.8 to determine the required circuit rating?
Very good point. I've got a call in to ask him. Is there a way I can tell by looking?So this time you got lucky.. the breaker he installed may be appropriate for the wire he installed.

Great post. I especially like this point: "...if they can compete then they're worth keeping if not then let them die."'worked' past tense; Clearly you're not familiar with my nuclear postings
Prediction: Coal has fallen. Nuclear is next then Oil.
The Tesla Wall Connector should be configured to match the rating of the circuit breaker, never higher than the circuit rating. If the circuit breaker is 50A then you need to set the Wall Connector to 50A. The Wall Connector will limit the maximum charging amperage to 80% of the circuit rating. You don't need to calculate the 80% rule as this is programmed into the Wall Connector.Yes, the wall charger should be 80% of the breaker.

The electrician likely did not configure the wall charger settings for a 50a breaker. It defaults to 60a when it is first powered up and you must sign in to its broadcasted network to configure it to the correct breaker size. Annoying, but not the end of the world. You do need to reconfigure the connector for the correct size breaker.The Tesla Wall Connector should be configured to match the rating of the circuit breaker, never higher than the circuit rating.
