This Will Save Your Life if You Charge Your Tesla on 14-50 Outlet!!

The day we took delivery of our first Tesla Model Y, we had a 14-50 outlet installed in our garage. This outlet was great because it allowed us to utilize the provided Mobile Connector to charge our new Tesla pretty fast in the garage.
Using a 14-50 outlet to charge a Tesla gives you a whole range of possibilities. NEMA 14-50 seems to be the standard plug type connector in the EV charging industry. With that, it is more important than ever to make sure your plug is up to the task.
The fact is that most NEMA 14-50 outlets are made to be plugged in once and not unplugged for years. The constant high power load on these receptacles, combined with the frequent plug and unplug cycles, makes these a potential hazard. In fact, there are many stories of failed plugs, and in some cases, fires that happened when charging a Tesla.
But with such a wide range of EV chargers available in NEMA 14-50 configuration, does that mean I can't charge my Tesla with one? The good news is there is actually a safe and effective way to charge your Tesla, or any other EV, using a 14-50 outlet. The key is making sure the receptacle is up to the task of long and frequent high energy pull.
This is where you need to start looking at Industrial Outlets for your solution. Many high end, or industrial outlets are made to handle a much tougher, hotter and frequent load. The 2 outlets that are most commonly used (linked below) are the Hubbell and the Bryant NEMA 14-50 receptacle.
The Hubbell and Bryant NEMA 14-50 plug are both made from Hubbell and both appear to be basically the same. These are both made to withstand the high temperature needs of charging a Tesla. With these 2 options, you will have a much safer charging experience at your home.
The first thing you need to do if you have a 14-50 outlet in your garage is to remove the cover and see if it is the most common NEMA 14-50 receptacle out there, which is the Leviton outlet. This plug can be found at your local hardware store for around $15 and is not suitable for the high demands of an EV charger. In my case, I was luck that my breaker panel did its job and protected me from being electrocuted.
Dont put yourself or your family in this kind of danger. Either directly wire your wall connector with the assistance of a professional, or make sure you are using a suitable 14-50 receptacle.

I had a NEMA 14-50 plug recently installed in my garage to charge my Model Y. Three things: (1) I insisted on a commercial grade Hubbell 14-50 receptacle. They are expensive - but they are high quality and are actually called out by name in the Tesla installation guidelines. (2) I have a metal plate installed around the receptacle - not plastic like the one that charred and melted in your incident. (3) I leave the mobile connector plugged in ALL the time - I never unplug it. I would highly recommend that you buy a 2nd mobile connector and use it exclusively for road trips and leave your garage mobile connector permanently in the receptacle.

I also went the extra mobile connector route. You never know when you might forget it. I know it's ironic to recommend this on a safety minded video, but for emergencies I also carry a 25ft heavy duty 110v extension cable. I'm careful with where the cable is laying and reduce the amperage that the car is drawing if I were to use it, but it's really helpful for cabin trips to rural areas where you might be parked for a day or two and can trickle charge back up. It would also be helpful if there was ever some kind of weird emergency with the supercharger network while traveling. 110 is everywhere, but not always in range of a parking spot. To the video OP, I've always hated the 14-50 plug. It's chunky and difficult to grab without feeling like you're getting your fingers way too close. I wish a handle was standard with those plugs.

I have a similar set up and had an event with a Tesla that was using our charger (the Tesla draws more amps) vs the Chevy Bolt that we had at the time. No fire or sparks but I could smell that something was not right and shut the circuit down and let it sit until I had a professional look over my system. The weak link in my installation were the DIY connections. To fix this set up each connection was checked and tightened and un tightened 3x to make sure that the braided wires conformed to the anchors properly. Sooo... you don't just torque it once and think that it is good! Back if off and retighten three times. It may be different with a solid copper wire but I thought this was important to share. I will replace my outlets with the better ones. Thanks and glad you and the family are safe!

Finally, check your torque on the screws every 6 months. The heat-cold expansion works it loose too. Best quality like Hubble and Bryant are a must. House fire vs. a few bucks for a better plug is a no-brainer.

Have a 35 foot cable run from the sub-panel and 110 foot run from the main panel. The 50 amp run in the garage is in flexible metal conduit and runs through the wall into an Eaton metal external box. Was installed by an electrician who did my solar installation and I have only unplugged it once to take photos. It's also recommended to unwind the cable to avoid heat buildup. My wife had not done this with her Kia EV6 and the cable was very flexible hot after 7 hours of 32 amp draw. Since then I instructed her to park so that the cable is fully unwound and no longer have heat problems in the cable.

Same exact thing happened to me. I had a Levitron plug working fine but then i ran into a problem with my charger. I had to take the charger into the basement for repair and then brought it into the garage to test it (which caused me to plug and un-plug it many times). This is when it failed. The issue with the Levitron is that the springs on the Hot leads start weakening and this leads to a loose connection on the hot wires. Arcing will occur which cause the plug to fail. Luckily i smelt burning and caught it early before more damage was done. I wound up buying the Hubbell. I now also unplug my 14-50 outlet and clean the connectors with steel wool as well as DeOxit every six months just to be safe. I'm glad to see you torqued your connection. This is very important step during installation that a lot of people don't do and just guess at the torque. thanks for sharing your experience.

Glad you are doing ok and nothing else is damaged and avoided getting zapped or worse. Another thing to mention is that plugs from the big box stores are not designed to handle the long continuous higher amp/voltages. There might be other differences inside the plug that you can see unless you tear them apart. Might want to check the number of unplugs the outlet allows and start counting the times it's unplugged/plugged and replace when you get close to the magic number. Recommend checking out State of Charge as he has a video talking about these plugs.

Good info! I'm curious about two things you didn't cover though. One is how your main breaker tripped before the dedicated 50A breaker: seems like the 50A breaker is not doing it's job. Second, you showed a burned finger: how was there enough current while plugging in or unplugging to cause that type of burn? Unless you unplugged it while the car was charging, there should be minimal current being drawn when you first plug it in (i.e. while your hand is on it).

I have an extension cord plugged into my receptacle and we plug and unplug our charge cord from the extension rather than the receptacle. There is a handle on the cord which helps unplugging. It was a bit of a fluke that we needed the cord - but now I am glad we did. We have only unplugged from the receptacle once. But we take our charge cord on longer trips just in case so it has been unplugged about 10x

@therealctoo4183 9 ай бұрын

My feeling is that whenever you buy anything, be it a shaving razor, a car, or an electrical outlet, you should consider that it will have a limited life expectancy, which will vary by the wear applied to it. It's well known that plugs receive the most wear when plugging in and unplugging, so my solution is to not unplug unless necessary, such as when we take a long trip to visit relatives. I have a NEMA 1450 that I use to charge my Tesla. I don't remember what brand and can't find out because that requires unplugging, and I knew before installing it that I wouldn't want to be doing that. I don't like leaving the mobile charger connected when not in use because it uses enough power on its own to stay warm, so I put a 60 amp switch between it and the breaker. I've had that set up for over a year now, and the only time it gets warm is when charging. My plan was that if it ever gets hot I'll replace it, but that hasn't happened yet. I know that it will happen someday, no matter what brand I have.

We also don't charge much over 90 to 95% so regen doesn't abuse the full batteries every time we drive.

Is there anything in the procedure for connecting and disconnecting that plug that prevents hot switching? If there is any ability for intelligent switching sequencing, there should be no current draw at all at the time the plug is connected and disconnected. It's like unplugging or plugging in a hair dryer while the switch is on vs having the switch off. The instant the plug makes contact, if there's a big current surge, the heat generated is very high at the contact point because the resistance is high. Power is resistance times the current, and that high heat from the power will degrade the contacts. Did the power supply equipment have any way to be turned off prior to connection or disconnection?

I used to be an advocate of using NEMA 14-50 outlets and a mobile charger or a plugin wall mounted EVSE. But, after a couple melted connectors, it just seems too easy for electricians to cut corners or simply not understand the needs of EVs. So, like Tom's recommendation on State of Charge, I now advocate hardwiring an EVSE if possible. Nearly all wall units have a hardwire option. If you need to use a 240v outlet, leave the EVSE plugged in at all times - plugging in and out of the outlet will ware down all but the most industrial outlets - which can lead to a short or fire. You also run the risk of moisture ingress if your outlet is anywhere it might get exposed to weather (near garage door). With a plugged in EVSE, I recommend inspecting the terminals and outlet every few months to make sure it is still safe. Of course, all this is avoided if you just hardwire with appropriate gauge wiring.

Hardwired my Tesla Wall Connector…the $90 plug was the reason I decided to go with the Wall Connector over the Portable Connector. Plug is only rated for 50A was another motivating factor while the Wall Connector requires a 60A breaker to run at full 48A output.

its really not much difference in cost in the end. In some situations that make 14-50 more practical, there are some things to look out for and I hope this directs those people in the right direction

Actually in most states now if they follow 2020 or newer NEC electrical codes, you're required to install a GFCI breaker in your panel for a 14-50 outlet in your garage. Those breakers are like $120-$200, combined with the $90 9450 Hubbel plug, you're halfway to a dedicated wall charger with a standard $18 breaker. Alot of EV chargers also don't like GFCI breakers as well.

What size wire (copper or aluminum) and breaker is feeding that panel in your garage? Seems like smaller feeder wire at the mechanical lugs, is it a sub panel? Also what size wire is feeding your 60 amp charger? I would recommend hard wiring your charger and delete the receptacle which is not rated for the 48 amp output that the 60 amp breaker setup typically gives you especially over a longer period of charging thus adding additional heat. You’re really pushing that receptacle to its limits. I typically install the 14-50 on a 40 amp output with a 50 amp breaker setup. Glad you weren’t harmed. Thanks for the useful content on the cycle ratings for that receptacle. Cool find.

If you were going to add the extension you would have been much better of leaving a single U shaped loop on each wire. This ensures there is no undue tension on the cable after you secure it down. In Australia we have much better designs for high amperage plugs. There's usually an outer retaining plastic screw bezel which locks the connector to a corresponding thread on the socket and they are nearly all switched. We only have single phase 230VAC and three phase 400VAC so no split phase sockets like the US which seem designed to kill you.

Hubble/Bryant plugs are much deeper than standard plugs as you found out. Hubble makes metal J boxes that are designed specifically for these deeper plugs. The diameter of the nylon portion of the plug is also larger than cheaper 14-50 plugs, and Hubble sells a metal faceplate specifically for these larger plugs. It is recommended to install 14-50 plugs being used in EV charging installs inside metal j boxes with metal faceplates to help contain the fire/melting potential in the event of a failure. I would recommend you do that, especially since you have the box mounted below your panel, and as you saw in your previous install, the fire can burn right up through the plastic j-box/faceplate and straight to your main panel.

My NEMA 14-50 was installed 6 years ago for the 40A Gen1 mobile connector. Tesla advised to leave it plugged in, probably due to limited number of receptacle insertions. When you bend wires to fit in box, they can loosen, so always re-torque before final assembly. Many electricians perform the wiggle test on wires and re-torque. The cheap Leviton receptacle is good for about 10 insertions similar to number of times a home owner might change electric range over a lifetime. The $55 Hubble is often used at RV parks where insertions are hundreds. Never insert or remove a NEMA 14-50 plug with power on. It’s much too dangerous !

Most important thing with there high power 240volt 8,000+watt outlets is first make sure the wires are torque to spec and recheck them ever year. 2nd make sure that it’s tight when you plug it in.

Fewer points of potential failure, and now my Mobile Connector is always ready in my frunk.

@@SINasTER75 An EVSE draws very little current when it's not charging a car, and as such it would never cause arcing when unplugged in that state. I agree it's the metal not the plastic that ensures a good electrical connection, and I agree it's important to replace the receptacle if the connection is no longer nice and tight, but... The plastic is different, and that's important: Hubbell uses a plastic called Bakelite which has been around for a long time, but isn't used much these days. Bakelite doesn't melt the way other plastics do. This helps contain the situation if a poor connection to either the supply wires or the plug causes it to fail.
