32 Amp Circuit on Wall charger question

[daforce]

I've just had my Tesla type 3 wall charger installed. It's on a 32 Amp circuit and connected in 2 phase. If I set the charger software to 32 amps will this be ok? Or should I give it some headroom?

Doesn't the manual only show single or 3 phrase install process? Didn't think 2 phase was possible

I haven't heard of a 2 Phase Installation either.
Generally if you've installed the Device on a 32 Amp Circuit with appropriate size wiring I would think you should have used a 40 Amp Circuit Breaker.
If this is the case 32 Amp Operation should be fine.
If it is actually a 32 Amp Breaker only, I'd be include to set the Gen3 Charger to 80% of that for safeties sake and look at 24-25A Maximum.

two phase (common in rural areas) works fine, but will be limited to 16A per phase on Model 3 and Model Y, just like three phase.

And yes normally a 40A breaker is installed for a 32A continuous load, though the installation manual does talk about "a three phase circuit breaker capable of 32 A continuous output"

Yes its a rural location with 2 phase quite common. The wall charger actually does have a 2 phase section in the manual. Its set to 20 amps which is power company limit (ergon). I guess Its good to know i could go a bit higher if I have to,

Actually, I've just realised its on a 40amp breaker. So 32 Amp ok!

Just as a note, a 32A circuit breaker with a 32A load continually is not going to disconnect. Perhaps at 32.5A it MAY pop after a week of continual load. It's just so low in the thermal tripping curve.

Its okay to just say put it on a 40A breaker, but then you have to size cables for 40A rather than 32A.

Yea the sparky installed it all with future upgrades in mind. So its on a 40amp circuit with very thick orange cable so im sure its all good.

As pointed out by @[Zombie] the car won't do more than 16A per phase if more than one phase is active anyway.
