Feb 08 2019 - Update, it appears my Wall Connector with 14-50 Plug has vanished entirely from the Model 3 Charging page after I installed mine and published this article. I'm reaching out to Tesla to find out why, and will update this article if I hear back. Meanwhile, the Google cached version of the broken URL still works, and the manual hasn't been pulled.

- Wall Connector with 14-50 Plug
A Tesla 14-50 Wall Connector is your best charging solution with an existing NEMA 14-50 outlet. Offering a 25 percent faster charge compared to the Gen 2 Mobile Connector, the 14-50 Wall Connector is easy to use and convenient to install around your home or office.
Utilize an existing NEMA 14-50 outlet for an easy installation, no electrician required.
Simply mount your Wall Connector to a wall or post and plug in.
Provides 40 amps (9.6kW) of power for all Model S, Model X and Model 3 Long Range vehicles. Model 3 Mid Range and Standard Range vehicles will charge at 32 amps when using the 14-50 Wall Connector.
14-50 Wall Connector Installation Manual
I'm not saying this particular EVSE, the new Wall Connector with 14-50 Plug, is the one for you. I'm only saying that that after reading this article, you'll be able to make a more informed charging solution decision for yourself. It really depending upon your requirements, garage layout, and budget. Also have a listen to this podcast segment that explains that your charging losses may be roughly 5-10% less at 48 amps than at 40 amps, so go with the electrician-installed Wall Connector if you can afford to wait for one ordered from Tesla and installed by an electrician, who will likely also have to upgrade your wiring and breakers. If you already have a NEMA-14-50 though, the Wall Connector with 14-50 Plug might be a great choice for you.
The Tesla Model 3 is fast becoming a popular car, and the base prices are due to become lower this year, which should accelerate sales even further. In the Luxury Vehicle category, it was the best seller in 2018, and it's the first American car on that list in many years.
Brisk sales also means a lot of first time EV (Electric Vehicle) buyers like me will have an experience much like mine: The car can be ordered and picked up in well under a week now that production has ramped up, but that's far faster than you can get an electrician to your house. Finding the exact details to tell your electrician was a challenge for me, and I wished a detailed article like this one existed. My family enjoyed over a thousand miles those first 2 weeks, and we sure are glad we live only 4 miles from a Supercharger, which was free for our first months of Supercharging.
Why the urgency in getting a charging solution installed in our garage? Because charging at home at 3 to 4 miles of charge per hour from a regular wall outlet wasn't exactly cutting it for our multi-hundred, dead-of-winter family road trips during the multi-week wait for an electrician.
Worry not, the Model 3 is a wonderful car. Coupled with a new charger that came out just in time, and I can safely say that things worked out very well for me and my family in the end.
Let me help you navigate the many charging options for the Tesla Model 3, listed at the online Tesla Store here. Note that it's often not exactly easy to find some or any of these in-stock at local Tesla locations, at least not for me here in CT (Connecticut), with no dealerships state-wide, and zero charger inventory at Tesla Service Center of Milford CT.
Remember, my shopping was for my Tesla Model 3 Long Range Dual Motor, your needs and battery capacity and charge rates will vary, see Tesla's Wall Connector article for the latest details.

No electrician? Just plug into a regular outlet using the provided adapter, but you'll only see a 3-5 mph charge rate.
Gen 2 Mobile Connector Bundle
This is the charger the Model 3 comes with since 2018, and should be kept in the car. You can buy another to keep in your garage. The current "Gen2" version limits charging speeds to 32 amps, versus the 40 amps the Gen1 units came with. Hard to find a definitive answer why this reduction.

Corded Mobile Connector
I also asked Milford CT Tesla Service if this accessory listed under Model S Charging was safe to use with the Model 3 for long term use, and they were unable to get a definitive answer. Since it has the hard-wired NEMA 14-50 cord, it should get a 40 amp charge rate. But then why isn't it listed on the list of chargers for the Model 3?
Electrician hard-wires Wall Charger for you.
This is also known as the HPWC, High Power Wall Charger.
Silver or Gloss Black Wall Connector, in 8.5' or 24' lengths.
This pretty much requires an electrician install it, although I realize some DIYers will take this on themselves. I'd rather have my insurance company know my electrician pulled a permit and passed an inspection, should something bad happen some day. Yes, you are paying for that.
While the signaling between Wall Connector sounds good, that would mean you're assuming both EV cars in your garage someday would both be Teslas, and both would use the same style of charger. There's also the additional cost in having these signal cables connected to consider, really only needed if you have only one circuit in your garage. I now have enough juice on hand for two.

My patience waiting for a better solution had paid off. You see, I had suspected that more charging solutions might be available soon: I didn't want to buy another 32 amp charging kit knowing a faster solution might be on the way. I'm glad I waited a bit.
Given I knew these would likely sell quickly, and that it met my needs quite nicely since I already had a NEMA 14-50 outlet installed, I ordered mine that very same day. Good thing I did, because currently (Jan 30 2019) it shows as Sold Out, unfortunately, and it won't let you pre-order. Just a gray "Out of Stock" button. Perhaps your local Tesla dealer has some? Note, this charger decision is a big commitment, and once the box is opened and the unit is installed, you won't be able to return it.
Why did I choose #4? Many reasons:
- Slightly thicker charging cable compared to Corded Mobile Connector
- A fellow Tesla Model 3 owner that I trust had warned me that the thickness of the 47 amp Wall Connector is a bit much in your garage, and I wanted my wife to be very comfortable hooking the charger up on occasion too
- I also didn't really want to wait for and pay for another electrician visit to mount a Wall Charger when one finally did arrive.
- I would also likely struggle to find any electrician willing to deal with my narrow installation space, since the metal back-plate that the charger fastens to requires side access and clearance to get to those 4 side-mounted screws.
- Getting a Wall Charger with a tidy 8' cable would mean it would have to be something to step over rather than sling from my ceiling. That doesn't appeal to me long term.
My goals for my garage were to have two spots to charge, with a bit of future-proofing. I wanted enough juice to handle two EVs at once in a pinch, even at 40 amps for each. Finally, it needed to go from 5% to 95% in under 9 hours, even in sub-freezing garage temperatures. This charger met all those needs. No DIP switch settings or troubleshooting, it either works or it doesn’t. This would seem to be likely to be easier for Tesla to support in the field, given the simplicity. If you poke round Tesla forums, you'll see plenty of stories about Gen1 Mobile charger issues at 40 amp and/or stories of Wall Connectors wired wrong by electricians.
By the way, as for future-proofing. If for some reason I ever want to step-up to 47 amps and a hard wired Wall Charger, that would be labor and a little materials to have the electrician upgrade the short lengths of #6 to #4, and the breakers from 50 amp to 60 amp in the garage subpanel, along with signaling cable between them. It's unlikely to ever be a road I'll be going down. Plain old NEMA 14-50 outlets I now already have will do nicely, even if our family's second EV (maybe someday) is a shorter range non-Tesla vehicle.
You may be able to save money and have your electrician home-run (direct) attach your #6 wiring to your home's service panel, skipping the subpanel in the garage. For me personally, I'm glad I'm unlikely to need any electrician to go into my basement and string 80' of cabling to my garage again. Any future upgrades are likely done right in the garage.
I only have about 2' of clearance on either side of my charger. Getting my wall bracket on was the easy part. But fastening those blue thread-locked screws that come with the Wall Connector was a bit tricky and required some carpentry, since they're side mounted. Once that was done via some holes and a long Torx driver, I then mounted a Tesla Cable Organizer to hang the charger handle below my Wall Connector. This worked out nicely, as you can see (more pics and videos to come).
Disclaimer: I'm not an electrician. This article is FYI only, a starting point to help you make a more informed decision when discussing your options with your electrician, given your home's layout and exact vehicle type. Your home's safety and following local code is clearly you and your electrician's responsibility, not mine. Please contact Tesla Home Charging Installation with questions.
Here's the final BOM (Build Of Materials) for what Elliott Bell from BCL Electrical Contractors installed:
- 1 125 Amp GE Model #TLM1212CCUGK Subpanel in my garage, with two 50 amp double pole breakers
- 2 NEMA 14-50 outlets using 2' and a 25' lengths of #6 THHN wiring (only one oulet is currently in use, but 2 can be concurrently used safely at a full 40 amps for each, with no need to wire a signaling cable between chargers)
- 80 ft of #1 SEU Romex to existing 200 Amp panel with new 100 amp dual-pole breaker
He also installed a Manual Transfer Switch with outdoor outlet that I already owned, for my portable generator that keeps key circuits energized whenever I have extended power outages in my New England home. This component has nothing to do with the Tesla, but figured I should mention it since the installation of all those wires can be seen in the time lapse video of the electrician. The actual time your electrician spends in your main panel is likely to be far less, to get your NEMA 14-50 outlet(s) installed.
This is a very long shot for me, should the Powerwall become more affordable someday. Installing a Tesla Powerwall near my main 200 amp service someday would be something really quite separate from everything installed for charging. There seems to be no way to really future-proof or re-use the electrical work I just had done for a Powerwall. Everything in my garage would likely left as-is. I currently just don't experience enough extended power outages to possibly justify the cost.
For Tesla Model 3 buyers, this time line will give you some sense of what you might be in for, when trying to convince you family how easy it is to charge your vehicle at home. Yes, because of a shortage of electricians listed, along with back-ordered online, and a lack of stock at local Tesla Dealerships, you may be in for a multi-week wait. In my case, it was a full month and a day before my 40 amp solution was finally installed, with a bunch of things learned along the way.
My Wall Connector with 14-50 Plug took until January 24th to arrive across country (CA to CT via FedEx ground), with no option to expedite shipping. Good thing I was able to use my NEMA 14-50 for a nice 32 amp charge while waiting, and taking that Mobile Connection kit with me on longer road trips, just in case. The day my Wall Connector with 14-50 Plug arrived, it turned out that a surprise road trip was needed that evening to visit distant family. That meant a bit of a rush was on to get it installed right away, to be able to charge even faster right in our garage. I was only at 70% battery and needed 100% asap, and we were trying to avoid the need to Supercharge along the way for this particular time-sensitive road trip. Yes, I was able to easily get this installed myself, on my schedule, with 4K video recording of me doing it, still working on getting that video ready to share.
Going back to the beginning, here's how my quest for a good home charging solution began:
Dec 18 2018
Model 3 Long Range Dual Motor deposit placed.
Used Tesla's Find an Electrician site used to get an appointment for an estimate.
Dec 21 2018
The listed Electrician arrives to discuss installation, but Tesla requires him to have several inches of clearance around the Wall Charger and that concerns me a bit, as I then cannot mount between my two garage doors. We discuss ways of mounting on the far wall to the right rear of the Model 3, but crossing to the left rear would be clumsy.
Dec 23 2018
Model 3 delivery date in Mt. Kisco, NY, 88 miles from home.
Dec 26 2018
With only one electrician listed on Find an Electrician site for my area code 860 in Connecticut, I use Home Advisor to find more, with two responding.
Dec 27 2018
Second electrician visits to give an estimate, not available to do the work for more than 2 weeks.
Dec 30 2018
A third electrician visits to give an estimate, available to do the work sooner.
- Jan 07 2019
The chosen electrician was Elliott Bell from BCL Electrical Contractors, who worked diligently from 9:30am to 6pm to complete all specified work, see also time-lapse below. Here's the work that was performed.
Jan 15 2019
Wall Connector with NEMA 14-50 Plug announced, and my order placed.
Jan 18 2019

Let's look at that article's first table:
Model Recommended circuit breaker for maximum charge rate
Model S 75D, 100D, P100D
Model X 75D, 100D, P100D
Model 3 Long Range 60 amp circuit breaker
Model 3 Mid Range
Model 3 Standard Range 40 amp circuit breaker
Multiple Tesla cars with 2+ Wall Connectors
installed for power sharing 100 amp circuit breaker
Now let's discuss the whole 60 amp breaker thing, only relevant for the Model 3 Long Range. Local electrical codes can vary, and electrician preferences may vary, so you may wind up with a 50 amp breaker, depending upon what your inspector says to your electrician. Either way, 40 amps max charging on a NEMA 14-50 outlet that uses #6 wiring to your subpanel (or panel) is fine even with a 50 amp breaker, which is how my configuration wound up. I get the full 40 amp charge rate for hours, with no issues. Note that the table on this charger info page confirms a 50 amp circuit breaker can be used for 40 amps of power draw. Will it trip on those hot summer days, when the compressor for my home's AC system kicks on? That is unknown, probably depends partly on how much my neighborhood's voltage sags on those days too.
The Sense Home Energy Monitor is said to now understand what charging a model 3 at home looks like, mine just hasn't picked mine up yet, and I'm not sure they're looking at supporting recognition at the various 32, 40, and 48 amp charge rates.
In case you're not familiar with the Supercharging experience when you're far from home, it turns out that I've already gone over 2,000 miles these first 5 weeks of Model 3 ownership for my leisure and for my work. I've already had a chance to try out all five of these northeastern US stations, for free, during these first 6 months of Model 3 Ownership, and I figure you might appreciate a little winter tour of each of these facilities, starting near Boston, ending in northern New Jersey:
- Framingham MA Supercharger
- Auburn MA Supercharger
- West Hartford CT Supercharger
- Danbury CT Supercharger
- Edison NJ Supercharger
My Sense Home Energy Monitor alerted me that it found my Tesla, nice!
It was about 10°F outdoors and about 25°F in my garage overnight. When I went to charge my Tesla while watching the Sense Home Energy Monitor, starting at 77 %. Turns out my washer and dryer happened to both also be running at this time as well. Because of the cold, the ramp-up rate of the Tesla Model 3 took about 20 minutes, according to my handy TeslaFi logs. This combination of slow rates and other activities in my home seems to have "tricked" the Sense to not noticing it was actually my Tesla charging. No activity seen under "Tesla" device. Of course, I'm not sure the washer and dryer running had anything to do with that, it's more likely it was just the very slow ramp-up due to cold weather. I'll happily provide this feedback to Sense in their forum thread. After 45 minutes, at 82% battery, I then stopped the charging.
A full hour later, I started charging again, with the battery still somewhat warmed and showing at 78%. This time, all went well, Sense immediately displayed my Tesla as it ramped up to full 40 amp charge rate in just a minute or two. This is good! I suspect my Sense will catch all charges when the weather is at at or above 20°F, which is a vast majority of the time here in Connecticut. So catching slow winter weather charges will be nice, but such nights only happen perhaps 4 to 5 times a year, so proportionally, I'm likely to now be capturing more than 95% of my charging activities.

I was able to attend a portion of this event in Hartford Connecticut at the DEEP headquarters today:
see also detailed agenda.
Assistant Vice President of IT
Spoke passionately about what his company is doing for the employees, and for the state. Having worked with this company in the past and been challenged with parking there before, this kind of thing sends a clear signal to employees that EVs matter. I enjoyed that Patrick shared some of the challenges and missteps he faced implementing charging stations way back in 2011.
- Green Mountain Power provides free residential EVSE & Fixed Fee for EV charging.
- SELCO Residential from Shrewsbury Electric and Cable Operations (Massachusetts) offers a free Wi-Fi enabled Level 2 charger.
- conEdison of New York is offering SmartCharge, with a free C2 device that plugs-in to car's OBD port to monitor charge times, and $20/month for no-charging during summer peak hours, $5/month for keeping the C2 device connected, and $0.10/kWh for charing off peak.
- School buses are a great fleet vehicle to consider, since they're not used in the summer peak period of highest grid demands.
Eversource is actually my energy company, so I certainly paid attention to incentives and ideas that Charlotte spoke of. She mentioned that the relatively flat growth of electricity in Connecticut is actually success, and shared some plans about the possibility of a utility managing Level 2 chargers. She also mentioned that all Eversource has offered off-hours rates to all customers, but it was barely used, and in her view, such a model of billing is likely to diminish over time. Such time-of-use rates are where the cost-causers pay. Set it and forget it is preferable, sending control signals to that customer's particular charger intelligently, with no customer action required.
Tesla Powerwall for $15/month was also something she was looking into, but another way would be to use the massive battery of your car for a more extended backup for home power.
Kevin George Miller
Director of Public Policy
Kevin mentioned that 400 of their chargers operating in Connecticut, and equated Network Charging to Smart Charging in his slide deck. Kevin shared a story where Baltimore did a pilot where they offered a second meter for EV-only charging, and it was successful. He also mentioned that there is a hearing in Connecticut this Thursday, requiring new construction to require EV parking.
One of the attendees mentioned Dr. Willett Kempton, who has worked on the concept of our EV batteries powering the grid.
Rocky Mountain Institute
Chris mentioned that DCFC (DC Fast Charging) tends to be roughly as expensive as gas, and that only much slower Level 2 is more affordable. "We have a problem."
For me, the best parts are talking with such industry leaders after the presentations, and I did get to share some charging and ownership successes and challenges with Charlotte, Kevin, and even Chris. Despite my short time there, what a worthwhile event this was for me, and I sure wish I could have been there longer.
I plan to share the entire day's slide deck, assuming it gets published.
Feb 13 2019 Update - The slide decks for each session are now available to clicking the various links here, or using the Presentation links I added inline, above. More links here.
I used my first ChargePoint station yesterday, over in Burlington MA. Gladly, both spots were unoccupied, but a glance at this Google Map photo quite clearly shows the challenge any such company has, when providing convenient spots, right near the handicapped spots. Yes, non-EV cars. Seems to fall in the no good deed goes unpunished category.

This next video is actually a preview of the Wall Connector with 14-50 Plug over a year before it finally came out, and now it's Sold Out after only 2 weeks. It's unfortunate that Tesla is having a hard time keeping up with the demand for home charging solutions.
