Yes, it’s total BS.
I’ll also share the flip side here, though, from https://electricaleducator.com/for-homeowners/nema-14-50-what-you-need-to-understand/ :
I spoke to Leviton and the general consensus is that the receptacles are not being installed correctly. Additionally, EV chargers draw a load for a longer period of time than a normal appliance. Homeowners and even some electricians are not using the necessary torqueing tools. Terminals that are too loose and, yes, too tight, will fail. Leviton came out with an upgraded version for EV chargers that we will do a deep dive on. If you’re installing an EV Charger, you should probably opt for the more robust Leviton product.
So, it is more dangerous than other appliances, and I’ve never seen an inspector check tightness. That said, I totally agree that it is unlikely to deter someone from installing one and more likely that people will do a shit job and it’ll be done without someone checking it. So, pretty bad either way, honestly.
This is something I wish more people realized. If it doesn’t fully charge you overnight, it’ll get you close, and it’ll likely be enough for your daily commute. It also generates less heat and thus is better for the long-term health of your battery to trickle charge instead of fast-charging all the time.
