Welcome to Blake Lite: a series of short videos which will serve as filler episodes to bridge the gaps between Episodes of Blake Check.
You should use commercial grade 15 amp plugs. They have heavier duty contacts and can hold up to something like a high power commercial floor cleaner or vacuum being plugged in and unplugged day in and day out. Afci gfci not needed as the mobile connector has those built in. If you get a commercial plug there should be very good contact between the charger and the outlet and so less heat should be generated. Check out youtube videos of people who've taken apart commercial quality 15 amp outlets and residential quality 15 amp outlets. unfortunately the commercial quality are usually like 5 times as expensive. Looks like yours had an internal short which is another indicator of the quality of the outlet. Also the reason you don't want to use an extension cable is the both the 1st and 2nd gen mobile connectors have temp sensors on the plug face. There are very few loads in a home which will pull the absolute maximum amperage for hours and hours day after day. even things like ovens or heaters or dryers will cycle on and off multiple times an hour. not a car charger. it really pushes the equipment to the limit.
Went ahead and upgraded to 220v nema 14-50.
Most home outlets are rated for 15 or 20 amps. BUT, that is momentary maximum, not continuous duty load. The TESLA 120v adapter will charge at a continuous 12 amps over a long period of time. So, what you're seeing is the effects of metal to metal transfer of current. Overtime, the 'hot' contact point will score and burn due to heat, humidity, dirt, oxidation, etc. It's similar to plugging a 1500 watt heater into a wall outlet and running it constantly. The outlet will heat and the heat will degrade the outlet. They just aren't built for continuous duty. But, you can plug in a 900 watt heater on the same outlet and run it 24/7 will little to no degradation. Current energy = heat energy. Eventually, as the outlet degraded, the jacket on the wire would also heat and become brittle to the point of cracking. That's where the GFI protection would have kicked in and tripped the breaker. The 240v with an appliance rated outlet is the way to go. Or the Tesla wall charger. Cause it looks really cool.
Wow! Great info. Thanks for sharing. Guess I do need to just go ahead and upgrade. Thank you! 🙏🏾
I’ve never seen an AFGF, just a GFI type. Thank you so much for the excellent information.
What doesn't kill ya, makes you ... wiser! 🧐 Thanks for getting fried so we don't have to! Nice website too.
Lmao. Happy to be of service 😅
why arent you charging with a 240? 110 is soooooo painful and slow
Don't need it. I'm working from home. And when I do go to work, my office is literally across the street from a bunch of superchargers.
This is just the information I needed
I’ve been wanting to burn my house down
Well you've come to the right place lol.
I believe newer chargers actually have a thermistor in the plug which shuts off if the temp goes too high. this is actually a very interesting failure mode here and it doesn't actually look like it was caused by arcing but just high temperatures. I don't suppose there's any chance you took it apart to see where the actual fault was?
I think you might be right. I did not, no. I exchanged it for a Gen 2 not too long after.
Master electrician here. Owner of 2018 model 3, and 2020 model x. You should not have been using the charger in a gfci anyway. Plus I wonder how far it is from the panel and is there too much voltage drop. GFCI protects against ground faults and shock. Not protection against fires necessarily. That would be more AFCI or arc fault. Too many electricians do not account for voltage drop. Not sure why you do not have a higher amperage charger provision anyway. When you make that kind of investment in an ev, you make the part as well to provide adequate charging. As others have medication traditional outlets are not made for heavy continuous use especially not most gfcis.
This video is from over 2 years ago.
There is absolutely no reason whatsoever to avoid using a GFI plug for charging the car, they're exactly the same as any other outlet in terms of appropriateness for charging a car, they're perfectly fine to use. A master electrician should know this.
You may want to study up on 20a outlets (circuits) vs 15a.
Extension cords never a great idea. A wall mount for the UMC better. Cheap and readily available.
This is a very old video. There have been many updates to the garage since then.
How was this your fault again? I think I missed it.
It’s not. Is also not that big a deal lol.
He should have not been using a gfci anyway and should have had a dedicated higher amperage outlet for the car.
@ariip uh oh! looks like I have a new fan. lol. 🎉🥳
May be time for a Level 2 Charger!
As a matter of fact it is. Appt scheduled haha.
GFCI trips if current leaks to ground. It doesn’t have temperature or current protection typically.
Are there outlets with temperature protection that you're aware of.
Bro fire 🔥 fire 🔥 fire 🔥
Love the site!!
Thanks bud!
