Can I use this charger?

Breaker trips then you know something needs to change.

In a perfect world but if the wire is the under sized part in the configuration it will cause an issue before the breaker trips.

I prefer better safe than sorry, others may have a different risk tolerance.

That cable looks like #10 at most. It's definitely the wrong amperage outlet for the size of wire.

Yes, you can plug your charger cable into it. To we safe, I wouldn't charge at more than 20 amps.

It depends on the breaker size.

What exactly depends on the breaker size?

The ampacity of the whole circuit needs to be coordinated. It's wrong to put a 50 amp rated outlet on a circuit with #10 wire (rated at 30 amps max) with a 30 amp breaker which code says can be loaded to 80% of it's rated size, in which case it would be 24 amps IF it was a single outlet on the circuit.

All I know is what I can guess from the photo. Looks like #10 wire, which is only rated for 30 amp. It could be #12, in with case it would have a max ampacity of 20 amps.

20 max load is the safe default in this case, unless it is a 20 amp breaker, then the max load would be 16 amps.

Oof. It's things like this that give EV's the bad reputation on social media for "burning the house down". ? I probably wouldn't try do draw more than 12A through that. Ratchet it way down, better to be safe than sorry.

Safest option. It makes my recommended max sound dangerous.

I realize there is code and wire size is important to the breaker and the load and it all should match up. You can take that 50 amp plug and wire it to a 30amp breaker with the correct size wire and it will work just fine. Thats what “depends on the breaker size means.” I wonder why nobody is taking into account the length of run from breaker to outlet?

The length of the run is less important from a safety perspective. It really comes into play for what the drop off will be in voltage at the plug.

Does Rivian stop the charge if it notices a certain amount of voltage droop?

It is frustrating not being able to see how many volts are on the circuit during charging. Even service mode does not have this info.
