PSA - this issue has been noted in multiple threads (see below for a good example) but it tends to get sort of buried and my goal is to elevate the visibility. If you installed a NEMA 14-50 outlet 4+ years ago as I did, you very well may have a lurking fire hazard. It is slowly becoming common knowledge that standard 14-50 outlets can't handle prolonged charging loads. Many standard 14-50 outlets were likely installed by an unaware electrician, and there are likely a large number of unaware homeowners. I admit to being one, and my garage almost caught fire a week ago as a result. Fortunately my breaker tripped but the plug and socket melted together, the outlet box melted, and the wiring insulation melted bare. I count myself very lucky. An electrician I trust came to repair today and said there is nothing wrong with the circuit, the wiring, or the charger (GrizzlE Classic); it was all because of a standard NEMA 14-50 outlet rather than an EV rated socket.
Please if you don't know, check yours now and replace with an EV rated socket. They often have a little green car logo on them. If this were a consumer product there would be high profile national recalls announced reflecting the extent of the danger but it sounds like the escape hatch is that they are not being used for their "intended use". If you search the topic you'll find plenty but you have to know to search.
Other best practices:
1. Set your charger or vehicle to charge at a lower rate than max, in this case max is 40 amp. Why not default 30 if you don't need that speed all the time? Its better for the circuitry and probably better for the car
2. Limit the plugging and unplugging into the socket as it can wear down the contacts.
3. Hardwire if you want to eliminate the socket.
And pass the word. . .
