Also not an electrician.

A concern for high current outlets in the US, such as NEMA 14-50, is that they weren't necessarily designed for a large number of plug/unplug cycles. Typically you'd plug your stove in and leave it there for years to decades.

If you use the same 14-50 outlet for car charging, which is not uncommon, the contacts can lose their grip over time. End users may want to take their mobile EVSE with them and incur cycles on the outlet. Properly installed but worn 14-50s have been known to melt or even catch fire under these conditions.

End users should prefer to have their EVSE(s) hardwired or installed with a higher grade outlet like Hubbell or Bryant.

Having charged 2 EVs on wall sockets for years, I've not seen them go over 12 amps, so that checks out.

One of those was a leaf

i'm always surprised how people here downvote correct information. This is 100% correct because heat in electrical wiring is a function of power (current) and time. The vast majority of electrical devices in a typical home use under 80% of their rated power. The few that do use their full power, like a resistive heater, often do not run continuously.

In contrast, it is completely normal to charge an EV at a socket's maximum power for over ten hours straight. This time component is why charging EVs from a regular AC outlet can be a fire risk.

That still didn't explain anything. Surely the car could limit itself to 80% of standard socket rated output for continuous draw, like they do in other countries. Are Norwegian outlets commonly installed so far below spec that that will cause them to catch fire? What was the impetus for this regulation?

What was the specific connector for that "dryer outlet"? Was it an L6-30 30A receptacle that was constantly getting nearly 30A of load, or a cheaply made 14-50 outlet?

> And since your car needs so much power stored in its battery to drive, it will probably pull more power than any other electrical appliance in your home.

Probably? No, it pulls less than my dryer which runs at 240V15A I think but also just the same as my 1500W space heater. You can totally control how much power the charger should draw.

> With that much power, there’s a risk of overheating and fire. Unlike a dedicated EV charger, a socket is simply not equipped to handle the amount of electricity needed to charge a car battery.

Wrong assumption leads to wrong conclusion. Any charger you can physically plug in will work in a house that's wired up to standard.
