EV Charger Plug fire - be careful! (Input requested. Link to pics below).
Dodged a full house fire last night. Outlet completely melted. Fire burned casing and wall, but went out on its own.
Equipment:
- Siemens versicharge 240/30A plugged into a NEMA 6-50 in a drive under garage.
- Dedicated line with 40A fuse
- Professionally installed during home construction.
Events:
- Charged friends MS 100D for 8 hrs during the day
- Charger rested for 1.5 hrs
- Plugged in a MS 75 to top off for the evening
- MS charged for a few hours then breaker tripped
Next morning I go out to find this near catastrophe.
Very scary. Melted box, all wood is charred.
Curious if I need to replace the entire wire (which is run through about 50 feet of walls in my house).
I read that EV chargers should be hardwired to avoid fault points like a plug.
Also read that most NEMA plugs aren’t intended to handle current for long periods of time (designed for a few hours running a dryer).
Electricians coming tomorrow.
Welcome any comments about how to protect myself in the repair/ reinstallation.
I’m likely going to hardwire the charger (no plug) and look into adding a temperature sensor or something - and definitely a fire sensor.

😲😳Wow!!! Sounds like it either the wiring is too thin to be used for household uses,needs updating on it wiring systems updated to current standard, either missing fuse for the outlets or their a blockage or obstruction in the electric current and last it could.be some idiots who didn’t know what they were doing in the first place either at the manufacturer warehouse at the moment or the person who did the wiring installation at the household. In my final opinion is too much power overload that charging is not needed as well as the polarity as well as ground wire needs to be in the right slot, right connection. I had a neighbor behind me two blocks away had their home shot up in flame cause of the wirings are wrong. No one has moved into that house ever since! Taxes were long overdued for that house and property space.
