30amp Wall Charger question (Specifically Charge Point)

[bigsky]

JUst a humble suggestion. Consider installing a 60 A breaker instead of 50. That way, you will be kind of future proofing your EV charging station, just in case.
When I had my Tesla charger put in, the Tesla-licensed installer wanted to use a 40 A breaker, which would have meant that my Tesla charger forever would be derated to 32 A maximum. I said no way; thus, I had a 60 A breaker installed to take full advantage of my Tesla Wall Charger output of 48 A max.
Perhaps your EV may take more than 40 A. If it does, you will be set.
I see other wall charges coming out with as much as I think 80 A charging capacity. That's overkill for me. 48 A is plenty fast for most home charging.
Please report how it all turns out.

Not all #6 can handle 60A. Not all 14-50 outlets can handle 50A which is why a 40A breaker is also approved for use with a 14-50R and why the mobile charger is only rated for 40A circuit/32A continuous. The electrician can verify which cabling is in the wall and then size the biggest breaker possible for future proofing. The Rivian has a 12kwh inverter (48A).

Instead of swapping the 14-30 to a 14-50, and using a permanent wall charger, it's a good opportunity to hardwire. If the OP is only going to use the mobile charger to save buying another or is a tenant, then a 14-50R is great and will only take minutes to complete the swap. I did this at our weekend house and it cost $100 in materials I didn't already have. I used 60A rated materials and breaker to future proof as you mentioned. However, 32A works fine for that typical overnight charge using the mobile EVSE. My primary residence panel could only tolerate an additional 50A breaker and 40A continuous on the hardwire unit isn't much slower than the 48A max.

OP, I am the homeowner of the home in question.

The drawback I see with the hardwire is that when my EVSE is getting old or out of date (6-10 years from now); or I sell the house to a new EV owner who'd like their own branded EVSE - it would be an easier swap than re-wiring a new EVSE.

I see a lot of posts gunning for hardwire, but not sure I see benefit?

Benefits of hard wire are that you don't have the expense of a plug and socket, it is safer and more reliable than plug and socket (plugs and sockets can overheat and fail).
It's trivial to remove the old hardwired EVSE and put in a new one.

*Update*
Electrician came out today, only $275 because the work needed was so minimal
-We confirmed that 6-gauge wire was already in use, ready to take on up to 50 amps (40 amps continuous)
-swapped out the breaker
-and replaced the outlet with a NEMA 14-50.
-Now just need to order ChargePoint EVSE and eventually take delivery of my R1S
