Home Charging Installation Cost

Home Charging Installation Cost

In preparation for my impending Model X delivery, I have started getting quotes for installation of a NEMA 14-50 outlet vs. the Tesla HPWC. I talked to two local electricians and two electricians that were on the Tesla website who are not exactly local, but within striking distance of my house. The local guys's quotes are $1000 to $1500 cheaper than the Tesla recommended electricians ($519 vs. $1500 - $2200 for the NEM 14-50 -- $500 more to install the wall connector). What gives here? Is this the Tesla upcharge or what? The local guys are both certified electricians who have done plenty of work in both my house and my office so I know they are good, competent, honest companies. Am I missing something here? Is there any reason to pay two to three times more for the same work? What have other people seen as far as price estimates for home charging installations?

First off, the $500 charge for the Tesla wall connector is fair. It is what Tesla charges for the thing.

Electrician cost varies all over the map. Sometimes a small independent can/will do the work for significantly less than a larger company. But, you do need to make sure you are comparing apples to apples. (Note that if the Tesla listed electrician has to travel a long distance, the cost will be higher to you).

Look at the quotes and make sure they are both doing the same work (permits/inspections etc). You will need the permit and inspection if you ever plan to sell your house. The buyer will most likely perform a permit search to get some level of confidence that the installation was to code.

Make sure the electrician inspected your electrical panel and has already figured out the wiring path from the panel to the 240V outlet in your garage. You don't want any surprises during the installation.

I just went through the process of selecting an electrician to wire 2 240V outlets in our garage. I ended up using one of the Tesla listed electricians. They were very prompt and described an installation that matched what I had already figured would be the case. I'm going to pay about $3k to get 2 50A circuits run from my box to the garage (about 70' total distance: down a wall, through a crawlspace, through a wall and up to an attic then down to the outlets in the garage).

All other electricians I tried to get to give an estimate didn't even bother to return my calls or emails (2 of these were also listed by Tesla on their website). Could be that some electricians are very busy and simply charging what the market will bear.

"Tesla tax"
You might get 2 completely different quotes for the exact same work if you ask for it differently: quote for installing a "NEMA 14-50" outlet most likely will alway be cheaper than "installing NEMA 14-50 for Tesla charging". Same work.

Just get a local reputable electrician to the work, they dont have to be listed on Tesla website - electricity is electricity.

MB2 | February 2, 2017

Perhaps I wasn't clear enough. The extra $500 to install the wall connector isn't the cost of the wall connector itself, it's for the extra cost of the larger gauge wire needed for the 100 amp line vs. a 50 amp line. I'm not including the cost of the wall connector, just the electrical work to be done.

I'm leaning towards the local guy. I agree, electricity is electricity.

Uncle Paul | February 2, 2017

I spoke at length with my Tesla recommeded installer, and learned that they are a different breed than an independent.

He had extensive specific knowledge of the Tesla requirements. Went over in detail the difference between using a 220 V wall plug instead of the Tesla wall connector so I could make my decision on which way to go. He had to get prior approval from Tesla to make the installation as they double checked his load calculations and approved his plans.

During and after installation he took pictures of my electrical panels and sent a package to Tesla including the report from the city inspector.

He took care of all the required inspections and met with the inspector to explain what he had done, got the sign off. Cleaned up after his job and spent some time to go over the charging protocol and reminded me that the car had to be unlocked before it would allow the charging cable to be removed.

He used upgraded components and took care to use all metal conduit which he bent to make it as cosmetically pleasing as possible.

He was $40 more than another quote I got, but his fee included the $200 inspection fee from the city.

I feel I got good value, he respected my time by showing up as scheduled, and finishing in the time alloted.

They have done over 800 installations, and have it down to a science.

Now Tesla has my specifics on file incase something comes up in the future.

MasterT | February 2, 2017

@phawker1 - sooooo, how much was it?

poloX | February 2, 2017

So, do we really have to be that accurate? Here is what I do and I found it to be enough. My electric company sends me weekly reports on my power consumption. On a aerate, my bill increases about $ 10 each week compared to before. So that is the cost to charge my car.

rickat | February 2, 2017

I had the same experience as phawker1, above. We used the Tesla recommended electrical contractor and had a very good experience. The person who came out to give the estimate was very knowledgeable about Tesla charging and explained all options, including the price differences. We wanted the Tesla wall charger, which we picked up from our local Tesla store. It was installed professionally with wiring hidden in the wall and we're very satisfied with the work they did. They also handled the permit and arranged for the inspecion (all included in the cost). We probably could have found a cheaper electrical contractor, but they wouldn't have had as much experience or been as knowledgeable about Tesla charging. For us, it was worth any extra cost.

poloX | February 2, 2017

Oops, just realized I posted in the wrong thread. :)

kilos1 | February 2, 2017

when i install my outlet is only cost me $395.00. i looked at the web site and found 2 electricians. once they known that it was for the car the price was higher. so i called a friend who know a electrician and he can over and installed the plug in my sub panel. not the main panel. plus it was installed behind the wall.
you do not have to use the website. call your local electricians and get a price.
i hope this helps, good luck

Starlifter | February 2, 2017

If cost is a consideration - the majority of the work can be done by the individual and then have a certified electrician make the final connections.

that being said, I prefer to pay a pro for the entire job. I have a buddy who's a union certified master electrician. he ran the proper line 50' from my main box to a new subpanel in my garage and then split it out on two 60 amp circuits. One to a NEMA 14-50 and the other to a wall mounted charger. He charged me 1700 for parts and labor - so $2200 for me all in with the charger.

interestingly - the wall charger didn't work at all when we turned on the power. it would light up green and then when connected to the car go red. turns out it was a bad unit. tesla overnighted a replacement charger and that's been working without a hitch. kudo's to their customer service for not quibbling and simply replacing the unit promptly.

campusden | February 2, 2017

I paid $370 in Florida, that included a $79 dollar permit fee. I have NEMA 14-50 outlet, 6 guage wire, and 50 amp bkr. I got 3 qoutes. The Tesla wall charger installation would have been cheaper except for the cost of the charger for 40 AMP operation. Now for 72 Amp or 80 AMP operation it would have been an extra $200 for larger wire, larger breaker, and larger Conduit for same length of wire, excluding the cost of the charger.

MasterT | February 3, 2017

@campusden - that's about how much it should cost, great deal!


Patswin | February 3, 2017

If your panel is located in garage what campusden paid is about what it should be. If Jena 14-50 outlet is installed within 10' of panel you are looking at about $30 of material and 2 hours labor. If you start getting into long runs through walls and crawl space etc, that's when the costs will start shooing up. Mostly for labor. I think 6 gauge wife runs about 80 cents a foot

poloX | February 3, 2017

I had 3 estimates for 1 NEMA14-50, right. Ext to my panel. The cheapest was $600 and they all refused to use the part the tesla recommends. Even when I tdl the I will buy it and would pay them the same price. They tried to lecture me that the high quality industrial heart duty 14-50 is no different from the home Depot $7.80 ones. Pissed me off so I got all parts including get a subpage, 4 CB, 2 50A cb and 2 100A cb and cables...and installed 2 outlets in my garage. Parts costs me about $500. Notice that the tesla recommended outlet is bigger than those from hardware stores so you can't find the cover for it. I had to diy it.

MB2 | February 3, 2017

I went ahead with one of the local electricians here in town. I just couldn't justify the exorbitant increase in cost from the Tesla recommended electricians. I'm sure they're nice guys and do a fine job, but I can't believe its two to three times better than the electricians around here.

As a point of reference, the line is going from my finished basement (with a drop ceiling) directly out to my garage. My breaker box is adjacent to my garage and the total length on line shouldn't be much more than 30 feet.

Insist on copper wire for any new run. Copper is far safer than aluminum.

Leoloanzon | February 6, 2017

I just installed an HPWC. I CALLED both Teslas recommended.andante non electricians. I. called about 12.electricians.
My recommendation is to open your main Breakers panel showing the label and wire caution.. :
These are live wired. Take a picture of the panel and all.labeling. Send all to all electricians.
You need. At least a 200 amps main source. If. Your meter reads Max 200 amp max and panel reads mX 125.Amp
You can upgrade your. Panel to 200.amp. Of course it dedepends on your aappliances and the total posible.amps
Most if not all electrician do not want to come and. check your panel. I was given numerous suggestions
From differen electrician like needing transfer switch, user side tap, auto clip,.etc. What I did was
Talk to,Colin, the main electrical head. Turns out Sun Solar was the only one who was acceptable
And had the lowest estimate. Electricians recomended by tesla are regularly being updated and. Trained
By Tesla. My suggestion is,. It does not mater if they were recommended or not, coordinated with Tesla's head.
My HPWC PASSed inspection with no problems. I thank Sunsolar for a job well done.

Leoloanzon | February 6, 2017

Sorry for spelling errors. The company is actually "Sun's Free Solar" Second sentence should read recomended and non recomended electricians.

jwh8000 | February 6, 2017

You don't need to open your panel down to the live wires to get the total output. Just open the breaker door and read the main circuit breaker amps It's stamped on the breaker.

COrich | February 8, 2017

Just had my 2 circuits installed yesterday. I am really glad I didn't try to do this myself even though I know how to do the installation. It really was a 2 person job running from the main panel on the ground floor down through a wall into the crawl-space, through a wall up to the garage attic and down to the locations where I wanted the NEMA 14-50 outlets. The total distance run was about 80 ft. I used one of the Tesla recommended electricians, and they did a great job (was completely turn-key for me). The building inspector comes tomorrow.

When I was younger and earning less, I would have done this by myself (pulling the permits and all). Not any more. At this stage in my life my time is more valuable to me than the savings by trying to do it on the cheap.

One note: Tesla requires that the electricians take photos of the job progress from start to finish.

knowinghowe | February 8, 2017

I was a Journey man electrician in a former life. I put two NEMA 14-50 outlets for < $200:
One located right at the electrical panel in my shed. Breaker, #6 AWG copper wire and outlet < $50 and about an hour of work. (I ran a neutral wire to this outlet, as this 50 amp outlet may be used in the future.)
The second I put in my attached garage, and this one I did not run a neutral wire, as the neutral is not used in charging the car and the location in my garage will not be used for another purpose. (I labeled this outlet "240V only, no neutral.) 125 foot of 6-2 romex with ground was $95 at Home Depot. Wire, big staples, big romex connector, breaker and outlet was < $150, and installation through attic to panel took most of an afternoon. (Have about 30' wire remaining after project.)

Shadowjack | May 4, 2017

I live in New York City and am planning to have a NEMA 14-50 outlet installed. If you have any recommendations or experience regarding a local electrician (Tesla recommended or not), I'd greatly appreciate hearing about it.

mzero | May 5, 2017

Shadowjack, we just recently installed HPWC out side and it costs us $650. This includes running a new circuit from service panel to the site (~70 feet). The electrician is from Long Island though. I posted a recommendation in New York forum. It's worth giving him a ring to see if he's willing to come to NYC if you could not find one from NYC.

jggorman | June 15, 2017

mzero, where is your post with the recommendation, I cannot find it.

LTO2 | June 15, 2017

Yesterday I had a Wall Charger installed by the Tesla recommended electrical firm. The charger is on a wall between the two bays in the garage, about 15 feet from the electrical panel. Installation cost $690 (Nashville, TN), as specified in a formal proposal prepared in advance by a person from the firm who came out to view the situation. Installers came 30 minutes early; finished in about two hours; cleaned up afterwards. Wiring is in metal conduits, carefully bent to cross a/c-heating ducts, and carefully aligned with bubble level. The installing company is also taking care of scheduling inspection and related paperwork. Installer took appropriate pictures to document installation for Tesla. Excellent work!

mzero | June 15, 2017

jggorman, I believe you'd have to log in to see it. It's under New York private group. Here is the link

Below is the content of that post:
I recommend Mike Howe, (516) 668-0686 for Long Island area. He did a great job running a new circuit and hooking up the HPWC. He asked for less that the one Tesla recommended.

I didn't know the guy before this as he was referred to me by a friend.

carlgo2 | June 17, 2017

Tesla recommended installers have to show their work to Tesla in order to stay on their preferred list?

Tesla does not require homeowners or random electricians to involve them?

Anyone can buy a Wall Charger without stipulations?

janandmona | June 17, 2017

We got two bids. One from the Tesla recommended electrician and one from a neighbor recommended electrician. The tesla was about $100 more but offered much more work. Hiding the new line from the fusebox to the roof. sealing the hole in the parapet wall, etc. Had the feeling the neighbor recommended electrician was going to toss an extension cord over the house. Your experience will vary.

derek_wilson_01 | June 26, 2017

The room with my clothes dryer is next to the garage. I paid an electrician $169 to flip the outlet from the wash room to the dryer so I could connect a 14-30R. My wife charges her Lear for 3 hours in the evening, then I plug in my Model S 75 so it uses the SDGE EVTOU2 rate from midnight to 5 am. As we both just need about 40 miles a day, this solution works for now. Considering adding a second 14-50 with the Tesla charger.

rvnotone | March 16, 2018

Hi All-
So I ordered the X 75 with expected delivery around June 2018- New Jersey. Regarding charging, my goal is to have a Tesla Wall connecter. What is the process? If I order one now will I get it in couple of weeks or is there a delay or something? Also, how much do you think it would cost me to get that installed and wired? Or should I just get the regular NEMA outlet and then upgrade? Please advise. Thanks!

markcohen | March 16, 2018

My thoughts on NEMA vs Wall Charger. First for most people the accelerated rate of charging that you get with a Wall Charger is not necessary. Unless I am going on a road trip I don’t come close to running the car down from the 80ish % that I charge it to every evening. And even if I did discharge it almost all the way, it would easily charge to full overnight with the NEMA 40A charge. I suspect that this is the same for most people.

That said... where does the Wall Charger make sense? First if you drive so much during the day that you need a quick boost over lunch, etc. Second, if you have or will have more than one Tesla, they are helpful as they will work together off a single circuit to charge multiple cars. Finally if you want to always carry a charging cable in your car (not needed for most people and applications), you might as well get a wall charger installed in your house as it basically costs the same as a second general purpose cable.

Middledawg | March 16, 2018

I have a friend who owns an electrical shop and he charged me the $300 brother-in-law rate. Didn't bother to seek any other bids.

One thing about a wall charger -- check the amps coming into your home. My townhouse was built in the 1980s and the developer was cheap installing a basic 125 amp meter on a board I share with three other households. In this day and time 125 amps is insufficient for today's power needs. What this means regarding my wall mount is that I can only run it at the 50 amp rate instead of the max to avoid taking down my entire house. That in turn means it takes around 7 hours overnight to charge my X. More modern houses feature 150 to 200 amp inflows. It you have that then odds are you can take full advantage of the wall mount's capabilities.

What I do like about the wall mount is the convenience. You just take the cord and plug it in. When you're done you wrap the cord around the wall mount and everything is neat. I recommend installing the wall mount for the convenience factor if for no other reason.

johnse | March 16, 2018

One thing to note is that the UMC Gen 2, that I understand is now standard on all Teslas, provides a max current of 32 A—not the 40 A the Gen 1 Model allowed. Also, your 75D’s onboard charger has a maximum draw of 48 A (the 100D’s charger goes up to 72A).

According to the chart at, 32A will net you about 20 miles of range added per hour. 48A will get you 30 miles per hour.

Installing the HPWC on a 60 A circuit will give you the 48A charging. As @markcohn said, if you get another Tesla, adding a second HPWC on the same circuit will allow the two cars to split the available current. If your panel allows, you can use up to 80 A split between two (or up to 4 with 4 HPWCs) car’s on a single 100A circuit.

As for cost, the installation of a NEMA 14-50 or HPWC should be about the same. It will mostly depend on two factors: how far from your panel is the connector? And how complicated is the run? The wire will run $4 or $5 per foot. The largest cost will be labor and the permit (depending on where you live).

rvnotone | March 16, 2018

Thank you for the feedback. I have the electrical panel in my garage and not far from my garage door.
Also, I have the 200 amp panel.

Goal is to get the tesla wall charger, but if the installation is going to be very expensive then I might just do the NEMA 14-50.

johnse | March 16, 2018

Other than the cost of the HPWC itself, the installation costs should be nearly identical.

rvnotone | March 16, 2018

@ johnse. Got it, thanks!

LTO2 | March 16, 2018

@rvnotone: I took delivery of my X75D July of 2017. Prior to delivery, I had a HCWC installed in my garage, within 5 feet of the charge port of the X, which provides an initial charge rate of 30+ miles per hour. The cost of the charger was around $600; installation by a Tesla-certified installer was near $600. However, recently I noticed that Tesla was offering the HCWC and installation for $1,000. Perhaps, this is still the case.

rvnotone | March 17, 2018

@ LTO2. Thanks for the info. For now I think the cost is $500 + tax for the wall charger.

I have an electrician coming in a week so will see what he says. Plus, my delivery is for June so have good time to get different pricing.

Appreciate it.

avesraggiana | March 17, 2018

I’m in Southern California, not exactly the cheapest place to get any work done on your house. Local electrician charged $700 to install the Tesla HPWC. He installed it almost directly behind and other side of the wall from the electrical panel, which saved me some money since the wiring he had to run was minimal.

As other posters have said, I too had to upgrade my circa 1990s electrical panel to accommodate the HPWC as well as an additional regular 240V NEMA 14-50 outlet. Total cost for that was painful.

Several months earlier, as a first step, I did have the 240V NEMA 14-50 outlet installed so I could hook up the mobile charger that comes standard. That cost me $200.00

rvnotone | March 17, 2018

I was just wondering guys. How about I just get the NEMA 14-50 outlet installed and then can I simply just plug the HPWC to that outlet? Thoughts?

Ohmster | March 17, 2018

^That would require some additional cabling and a connector as HPWC is not designed to 'plug in', but it could be done. Incremental cost is minimum. Not much benefit other than you'd be wired up and ready before car arrival.

Had ours installed for 300 including 60A breaker. Waiting for the signature referral unit so we don't have to play musical cars with the cable.....

johnse | March 17, 2018


As far as electrical code goes, the HPWC is not designed to be installed as a plug-in. The NEC has specific limitations on how EVSEs can be installed. Until a few years ago, almost any L2 EVSE required hard-wired installation.

That said, as long as proper wiring was used you could do that, but only for a max charge current of 40 A on the 50A circuit. Might as well just use your UMC, or find someone willing to part with a Gen 1 UMC.

rvnotone | March 17, 2018

Got it. I have until June so have good time to get this taken care off before delivery.

Appreciate your inputs as I am new to EV stuff...

rvnotone | March 26, 2018

@ LTO2 ; So you get 30+ plus per hour charge? How so? I thought the X onboard comes with 48 AMPS?
I have decided to go towards the HPWC direct install route, (no middle wires). So with that being said, the max miles per hour I will get is only 30.....Am I correct?

johnse | March 26, 2018

X75 comes with 48A charger, which Telsa rates at 30 range miles per hour

X100 comes with 72A charger which can get 45 rmph.

Both of those require direct-connected EVSEs, like the Tesla Wall Connector. 48A requires 60A circuit. 72A requires 90A circuit.

saiswanhtun | March 26, 2018

I hired local electrician and ask him to put 4 prong dryer outlet with weather seal in front of my house plus , upgrade my electric panel and other electrical job around the house for $1000 . After that I just use the charger that with MX. I hope it help...
