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.

@BeardedTeslaGuy 9 месяцев назад

I have extra mobile connector that stays in each car permanently. It was a good tip a few years ago and glad I went that route.

@NO_OPEC_NO_PROBLEM 7 месяцев назад

@Reck1025 4 месяца назад

@@BeardedTeslaGuy So your leviton outlet failed even though you didn't unplug your charger very often? That's scary!

@SSPsGoku1 Месяц назад

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.

@ericchang7759 9 месяцев назад

Similar thing happened to me. In my case, cheap plug and loose clamp eventually shorted. Using contact fluid like Deoxit is also highly recommended. 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.

@ahealingjourneyaz 7 месяцев назад

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!

Glad you found it before it got worse. Munro Live has an excellent video on the topic. I have had my 14-50 for 8 years now charging 2 EV's without issues. 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.

Be aware when you switch the outlets out the cover needs to have a bigger diameter hole compared to the standard 14-50's. You have to get a Hubbell specific cover plate.

@leeshesmith790 26 дней назад

Thanks for all the great tips. Glad to know you and your family are safe. Would it be advisable to just purchase the 14-50 piece that snaps into the charging base? Or do you recommend just buying a whole new mobile charger?

@therealctoo4183 9 месяцев назад

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.

@mikeyc8139 7 месяцев назад

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).

@brbshp7 9 месяцев назад

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.

@tedmoss Месяц назад

I checked the various plugs, and they are fine for the job that they were intended for assuming they are properly installed, just not for continuous charging. Just direct wire and eliminate a failure point.

@kranwa15 6 месяцев назад

Good choice, i recently installed a charging outlet for our Tesla. Did a few research, purchased the Bryant 14-50A outlet. By code and because it's not hardwire, need to install a 50A GFCI breaker. Identify if your electrical panel is a Homeline vs QO Breaker or Breaker Panel.

@carolan066 9 месяцев назад

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.

@tedmoss Месяц назад

By experience over many years, it is not necessary to scrub the connectors with steel wool, even DeOxit probably is not necessary, however, there are permanent compounds that are very effective, electrically conductive grease.

Wow, thank God you were not seriously injured! My first 14-50 outlet overheated and the Tesla charging system reduced the rate of charging from the Tesla mobile charger. Soon, it failed completely, and I replaced it with a higher duty cycle outlet. I did not plug and unplug the mobile charger to take with me for mobile use, the failure occurred with occassional use (weekly) about 3 months after I started using it. The first one was professionally installed, but it was purchased at a Big Box store for $10. I replaced it myself using a higher quality ($75) 14-50 outlet.

@mondotv4216 8 месяцев назад

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.

How often are you unplugging and plugging in your charger? Just wondering an estimated number of cycles before it failed? I've been home charging now at 32amps for 9 months. Maybe I should check the tightness of the lugs holding the wire. I did wiggle and re-tighten on the initial installation.

@angelmunoz501 5 месяцев назад

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.

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.

… re o unplugging it while the car was drawing power? Or, did you unplug from the car first, like the manual says to do?

@user-ku8yb6cf9f 5 месяцев назад

Same thing happened to me. I initially cheaped out and installed the Leviton 14-50 receptacle and used the included mobile charger for both home and work meaning I had to unplug the receptacle every day. The car actually warned me first by sending a message through the app of a high charging temperature detected which subsequently reduced the vehicle's charging speed. The receptacle was really hot. A quick internet search lead me to the Hubbell receptacle. It's noticeably heavier than the Leviton and I haven't had the issue since. It's surprising your electrician wouldn't have known that about your install. Great channel btw!

@BeardedTeslaGuy 5 месяцев назад

yea, that sounds about right

@dubmob151 12 дней назад

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.

@whoistrayy 6 месяцев назад

would just using an extension cord fix this issue aswell? cause you wont be plugging in and out of the socket just the extension cord

Thank God no major disaster. I had a Leviton outlet that stopped working after 4 years. It didn't burn like yours but resulted in slow charged\. I replaced it with a Bryant. Those Levitons are crap but electricians still use them.

@BeardedTeslaGuy 9 месяцев назад

check it and consider replacing with a heavy duty one

@JeanPierreWhite 9 месяцев назад

The good news is that at 30 amps the risk is reduced vs 50 amps. Leviton do make commercial grade stuff as well so it's not a bad brand, its using residential grade for a heavy duty application that the issue. Determine if yours is residential grade or commercial grade, there should be a part number on it. If it 10 years old or more replace anyway.

@david100483 9 месяцев назад

@@JeanPierreWhite it’s most likely a home grade one. The outlet was used for a clothes dryer and is original to the house, which is now a bit over 14 years old…so I guess this settles it lol. Thanks!

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.

It seems very suspicious that it is the ground that is burnt away. Normal the ground carries no current unless there is a short to ground or wiring error. Doesn't seem like any fault of the receptacle.

@RRooooooNNNN 6 месяцев назад

I have the 14-30 variant (Dryer plug as some call it). I bought extra mobile charger when I bought my M3 in 2021. It stays connected to wall, the original one stays in car. jus so i do get a ton of plug wear like that. scary. Glad everyone is safe. (At least as I'm 1 min in the video they are at least. Fingers crossed).

@travisyarbrough4033 3 месяца назад

We had a Nema 14-50 put in with industrial setup by an electrician that does USC Medical hospitals in all of southern CA. We are using a 200 amp panel and a 40 amp breaker and only using a 30 or 32 amp output. 10 to 12 hours is OK with us. We don't drive less than 40% so we are good. Temp stays down and batteries don't get abused by heat which kills a Tesla if fast charged only. We also don't charge much over 90 to 95% so regen doesn't abuse the full batteries every time we drive.

Even if you dont unplug in screws holding wire inside tend to loosen overtime which leads to contacts overheating and receptacle plastic getting warped and brittle. That may cause it to short out eventually.

Ugh,.. need to check the wiring on my OLD 10-30 wall outlet. Just got an EV and did quite a lot ot jigggling with it for the first few days until I got a "y-splitter" (which the mfg for some reason suggests not using, maybe worried that user will run two devices at once!). Now there's no fiddling about with the rickety feeling old wall outlet, both dryer and car charger are plugged in, and any (rare) unplugging is done remote from the wall, with hands able to grip both sides of the connection. Definitely now need to inspect for any damage the initial jiggery-pokery might have caused behind the outlet! Thanks for the heads up!

@teslainvestah5003 4 месяца назад

Stranded cables can squish and get looser during installation. The Excellent Laborer says to wiggle the wires and re-torque the screws, repeat 3 or 4 times, so that they stay tight. You might want to go do that if you haven't!

@jonphanspromotions 9 месяцев назад

I have Hubble Bell 14-50. Why would you unplug that many times to make it loose. I plugged my mobile connector in once and just left it there and all good for nine months.

@jimmcd5660 9 месяцев назад

Just replace it with an L-1450 twist lock receptacle and male plug end, you’ll be good with that, appears to be an arcing situation, wether it was a loose ground, or loose jaws in the ground pole in the receptacle from overuse (doubtful). Leviton is fine, hubbell/Bryant are the same company, and do make a more robust device, and pass and seymour is fine as well, just use a twist lock my friend. Doesn’t matter how shiny the steel is or the appearance of the nylon etc, most important is to keep the terminations screws in the devices torqued tightly.

@BeardedTeslaGuy 9 месяцев назад

I think most people would be surprised how tight 75 in/lbs is, and most probably are not torqued properly

@321brianh 5 месяцев назад

Funny enough I watched this months ago, it was on my todo list, I didn’t get to it, and I’m pretty this lead to an internal power surge that melted the pullout switch at my air handler. I can’t prove it but the timing would make sense between using the outlet and the AC going out due to an internal power surge.

@Shenee0 9 месяцев назад

Thankfully when I bought my Tesla a few months back I went and bought the Bryant plug myself before having an electrician install it. Never let them get it for you. Also the plated finish like that is if you get it install on the outside of your drywall rather than inside (told by an electrician)

It would be interesting to know how the contacts on the outlet are manufactured. Even if the outside of the two new plugs look similar or even identical the contacts inside maybe of different quality and design. Probably not but something to think about

@graff8162 4 месяца назад

It looks like someone made a mistake as a wire connection. Because your green wire burned down. I can assume that someone set it on fire with a lighter. I have seen this many times, but everywhere the problem was inside the outlet due to poor wire connection. I also recommend that all users of such outlets use this only at a current of up to 40 amperes. Similar sockets designed for short loads of 50 amperes, but not long.

@JeanPierreWhite 9 месяцев назад

Your advice to hand an electrician the Bryant or Hubbell outlet is spot on. EV's are new and very few are aware of the risks. They have installed hundreds of dryer outlets and never had an issue. Until now......

@danc2014 4 месяца назад

You point out the plastic looks the same but it is the internal metal contacts which is the important design. More metal more firm connection makes the outlet better. Also note the burnt outlet used a screw tip not hex bit. Could you get 75 inch lb with a screwdriver? The ground should also never be carrying current. Note the smaller wire size and if this happened while you were plugging in shows the car was drawing power at the time another error.
