So question for you guys regarding install. Rivian asks not to install a CFGI breaker, because the mobile charger has one in it, but I was told by an electrician, it's code to have one installed. Would this cause an issue?

One thing to keep in mind. For a 40 Amp charger use a 50 Amp circuit, 50 Amp charger on a 60 Amp. This is because the charger draws continuously for hours at a time.

Yes, at my home we have 60amp direct wire set up.

This is for the cabin and will be used a half dozen times a year or so.

10 years EVs and EVSE experience- and a geek here.

My biggest reco would be:

Wire and breaker for 60A. Not higher.
If you install only one EVSE, I’d make it a Tesla Universal Wall Connector (nacs and J)
Why?
1) both connectors in one reliable package, 24 ft cable. You get OTA updates, and simple app monitoring
2) down the line if you need a 2nd EVSE you can put another TWC on the same 60A line and they load balance virtually.
you may want another charger in a different position because of how you park, a second EV of a model that has a port in another place, or add another one in your driveway to charge up guests or your truck while outside.
3) the cars themselves support the scheduling for charging you may want.
4) even if you are an ultra geek, it is super unlikely you will do much with data feeds, APIs etc. After a couple of years of owning an EV it is as interesting to monitor that as it is to monitor your fridge. I.e. not much.
5) there is much talk, but not much delivery on any vehicle to load or vehicle to grid action. I would not invest as cent into any EVSE that claims to do this until I see it work live in production with the cars I own. At that point the investment will be larger, such as adding transfer switches.

First estimate:

Feed from house to garage $800.00 - $1,000.00

Garage panel $800.00

Charger receptacle $450.00

Tie in existing garage power to panel $200.00

Permit $ 75.00

So this is a detached garage at our cabin, so it's not as easy of an install. The panel is in the basement on that wall where the cabin runs next to the garage. They would have to run a line under the sidewalk, and into the garage and add a subpanel there.

I have two 14-50s installed for our 2 EVs. Both are Hubbell, industrial grade. One has a GFCI (installed in 2024) and the other does not (installed 2021).

I thought I could live with occasional nuisance tripping but of late, the outlet has become useless. With the 100 degree weather in the NE this week, it refuses to reset, even when nothing is plugged into the receptacle.

Is this normal or a sign that something is wrong with the breaker and/or the install? Should ambient heat alone cause the breaker to trip?

Most people have been talking about plugs and such...I'm going to go a different route...

First, I recommend you go do some snooping around on your parents' electric company website. Look to see if they have any rebate programs for EV installs. We used to have a house up at South Lake Tahoe (Liberty Utilities) and they have grant money for EV home installs. The gig was up to $1500 for the purchase and install of an EV charger. The trick was you had to use a charger on their approved list. When I did it, I was able to get a hardwired 50amp charger for a total of $1700 ($200 out of my pocket). It's worth a quick snooping.

Second, whether you go a pug or permanently installed charger, I recommend placing it on either side of the garage closer to the large garage doors - even if it's a more expensive install. The reason here is if you place the outlet on the wall next to the interior, then the EV MUST be parked in the garage to be able to charge (as most cables are only 24 feet long). When the outlet it near the garage doors (or closer to the drive entrance) the EV can be charged while parked outside and the garage door is closed. When I had the vacation house, the R1T literally just barely fit into the garage but we had friends who would want to charge and they could easily do so outside.

Just a couple other things to think about...
