The receptacle was installed over 8 years ago if I had to guess. It has charged the original RAV4 EV and 2 (or 3) Bolts. Their Juice Box was plugged in and not unplugged until almost 2 weeks ago when they started using the Lexus RZ350E Mobile Connector. I don't know what a Bolt pulls, 32A maybe? I don't know what setting my neighbors have been using over the years.
There was no tell-tale problem AFAIK. Of course zi don't hang out much in their garage...
Since their new car's port moved from the Bolt's driver rear fender to the RZ passenger front fender, I had my electrician guy come and move the NEMA 14-50 receptacle. Of course he agreed an EV rated receptacle should be used. I was pretty shocked when I saw the old one.
Perhaps
@OVERKILL,
@UncleDave or others can speak to the extended high load demands of EV charging.
There is a reason for the EV rated receptacles. I urge owners to do it right. As my grandmother from Ukraine used to scold me, "Don't fools around!"
