72 amp draw over 80 amp breaker

[Lamy29]

Looking to get an expert opinion, if it's ok to run a 72 amp draw on wallcharger through 80 amp breaker.

No. You need at least a 90A breaker for that. You can only draw 80% of the circuit rating for continuous load. With a 80A breaker you're limited to 64A.

Also, make sure your wiring is also up to code. It may not be as simple as changing the breaker.

everything is newly installed along with upgraded 200amp panel. Just made the mistake of putting in an 80amp instead of 90. Not a major deal. Missing like 4-5 miles per hour.

Max is 64 continuous amps on a 80 amp breaker. Your 80 amp breaker will trip after a while at 72 amps.

If the wiring can take it you might as well go to 100. They are probably cheaper and more available than a 90 amp breaker. Then if any older two charger Model S's show up you are good.
