Grizzl-E charger

[Stillk]

I recently had a 220 outlet installed with a 50 amp breaker. The Grizzl-E classic charger that I purchased is set from the factory at 40 amps. It can be adjusted for 16 24 32 or 40amps. Any suggestions for setting the charger at a different amp or should I just leave it at 40.

Thanks for the input

Following the "80% rule", leaving it at 40A should be safe for your 50A circuit. Your SE will never pull that much power, anyway (max 7.4kW for Level 2 on North American single phase power).

For extra safety margin, I dropped my Grizzl-E down to 32A since we also use it to charge my wife's ID.4 (which will ask for 11kW).

Leaving at 40 A is fine, that's 80% of your 50 A circuit. The SE won't draw more than 32 A, so you'll definitely charge the SE at max rate (make sure to check the Level 2 rate setting in the car).

Perhaps because of how lax inspection and code enforcement is in my part of the world, I'd be wary of trusting that a circuit actually has the Ampacity implied by the breaker's rating.

Following the "80% rule", leaving it at 40A should be safe for your 50A circuit.

my layman's understanding is that if a receptacle is rated at 50 A, and the breaker is rated at 50 A, then the conductors must follow the "80% rule," and have an Ampacity equal to or greater than the rating of the breaker at the temperature rating of the breaker, and that means 6/3 NMD-90, because no residential breaker is rated at 90°. Properly wired with 6/3 NMD-90, the circuit is fully capable of handling up to 50 A, according to the NEC.
