I have a dryer outlet that caught fire charging our little i3. I'm not sure why GP said "some countries" -- I'm in the US. The heat warped the plastic just enough to bridge one leg of the power socket to ground. It got pretty melty before the house breaker stopped things.

The torched outlet was installed specifically to charge prior homeowner's EV and was only 3 years old.

I moved to an EV-rated 50A outlet which can handle the duty cycle. We have charged two EVs off of it and so far so good. It has a cute little green logo on it and costs 5x as much as a typical NEMA plug. :) Weighs about 5x as much too and grips the grizzl-e plug very tightly and with much larger contact areas.

I'm a believer.

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?

The youtube channel 'State of Charge' has a number of videos talking about cheap connectors and/or lower spec connectors catching fire. Happens even on setups where people had a dedicated level 2 ev charger outlet (NEMA 14-50 , aka dryer outlet) but the installer used a connector not rated for enough current. See https://youtu.be/fzgxKChqjtc to start.

One needs to do one or possibly a combination of:

- Set the pin setting on a home charger for a lower current output. Theres also portable chargers with programmable current limiting, which I find more flexible.

- Replace with a better outlet/wiring setup. Many advocate for a hardwired setup over using an outlet.

		> NEMA 14-50 , aka dryer outlet The reason why I was asking for the outlet is precisely because "dryer outlet" can mean a lot of different things. Dryers in the US usually don't even come with cords out of the box because people may have a few different plugs. Does it have a neutral? Is it 30A or 50A? All possibilities for a "dryer outlet".
