Not sure how old would be old enough to be concerned, but I expect 1990 or later would definitely be fine, and 1940 or earlier would definitely be questionable?

Did they even make electric dryers in 1940?

... has plugs available for everything from a 14-50 to do ~7.2kW charging down to 5-15 to do ~1.2kW charging. The problem here was that the 14-30 plug was not available so an adapter was purchased from Home Depot or Lowes (not homebrew and not intentionally fly by night). The issue is that the charger uses some pinning in the plug to know what kind of outlet it is plugged into. Since it was using the 14-50 plug it didn't know it was on a smaller circuit. What was supposed to happen was the car was to be set to do slower charging and only pull a max of 24A. The last step was missed and the fact that it was charging too fast was overlooked. So it was still an error, but it was not an attempt to get away with something.

The people getting away with something are those selling the plug adapter that goes from 30A male to 50A female. This is just encouraging someone to overload a 30A circuit. A big part of the reason for different designs on differently rated plugs is to prevent exactly what happened here. An adapter to a different 30A plug or a lower rated female plug would be okay, but not to a 50A plug. Safety in these circumstances should not be dependent on a user who may not have any electrical knowledge whatsoever.

The equipment termination temp rating and the allowable ambient operating temp of the equipment are two different things. Not directly relatable.

Rather than try to win arguments for DIY's, why not give AHJ's the last word, since their job is to check this stuff every day.

The best way to prevent DIY, and electricians making mistakes on your house, is by requiring it pass plan review & inspection.

Whose trying to do that, Wish DIY was never allowed here in my area but it is. Seen waaayy to much DIY, handyman, and even GC garbage out there.

They do have the last word as long as they are accurately interpreting the codes. Issue would be that with DIY, handyman, and GC many don't ever get an inspection These DIY even if local codes enforcement asks for a permit and plan for an EV they don't even get one or an inspection.

DIY and inspection, let alone plan review? Someone lives on a different world.

What are you suggesting to forum members, and inevitable internet searches looking for DIY advice? Do it themselves?

I actually do believe that a person should have the right to burn down his own house. Unfortunately that fire might spread to someone else's property, but that is the price we pay for self-determination and personal responsibility. You absolutely should be against the government telling you whether you can or cannot do any kind of work in your own house. You are still responsible to do it correctly.
 
My neighbor setting his house on fire is absolutely my business. So sick of irresponsibly dangerous anti-social behavior being justified in the name of freedom. My freedom doesn't come at the cost of yours.

But what happens when you go to sell that property? If the work is properly permitted/inspected then it shouldn't matter who did the work. If no permitting was done, requiring the work to be brought up to current codes before you can sell it makes sense for public safety.

I didn't say it wasn't your business. The person responsible for the fire should be held accountable. But how far down this slippery slope are you willing to go? Can you do your own mechanic work? What if your brake job fails and you crash into an orphanage? Can you cook your own French fries? What if the oil catches fire and burns down a neighborhood? Can you make your kid's school lunch? What if he throws a banana peel on the ground and his teacher slips and breaks her head?

I believe that only people who know what they're doing should do electrical work. The problem I have is that the permit and inspection system isn't really designed for public safety. It is part tax and part absolution for the local government.

Shouldn't that also be the case for gas, load bearing carpentry, and drinking water?
How does permitting absolve the local government? Do you think they should have some liability for work they inspected but did not personally perform?
