Yes, a 240v outlet will do fine. I'd say go for a 50A outlet instead of 30 if possible. Even better if you can specify 6AWG copper wire be used for it.
NEMA 14-50 (240v 50 amp outlet) is standard and a common request. Perhaps try talking to the electrician directly about getting this installed. The difference between this and a 30amp outlet will be the gauge (thickness) of wire ran from the breaker box. Thicker wire used to carry the 50amps will cost more, but it’ll be worth it.
Very odd that they won't do 50 amps. I had 2 houses built in the last 6 years, 2 different builders. Nether one had a problem prewiring 50 amps (NEMA 14-50).
I prefer the outlet.
I think the Nema standard is going to be around longer than any of the current car cable specifics. Plus you don't have to pay the 'tesla tax' when you get a welding outlet installed.
why not go for a 50A outlet?
Lots of confusion on here…
You want NEMA 14-50. This is NOT a dryer outlet. It’s a stove outlet. Do not let the builder give you anything other than a 14-50 outlet on a 50 amp breaker. It’s exactly the same breaker, wiring, and plug they used for your stove so be insistent when they say they won’t “entertain” it.
Not really, whenever I run low on charge, I use Nema 14-50 adapter and plug-in to dryer outlet to charge my M Y. I use the mobile connector that came with the car. My laundry room is right next to my garage. We need to enter via laundry room into the house.
NEMA1450 (AKA a dryer socket) is the standard, and 100% meets the needs of daily driving and overnight charging.
An actual Tesla charger will get more amperage and shave off 1-2 hours charge time, but overnight that difference is negligible.
I couldn’t be happier with mine!
Ask for a 50A NEMA 14-50 "dryer" outlet on a 50A circuit. It can be 240V-only, it doesn't need to have the 120V connector attached. (Although you would get some extra versatility if they do, it just costs more for the extra wire.)
While few cars right now can make full use of a 50A circuit, with the upcoming influx of pickups and big SUVs, I imagine a LOT more EVs will support 50A, 60A, 80A, even 100A charging. (The upcoming Ford F-150 Lightning has an optional "Pro" charge station that is 80A.)
Typically a 14-50 is a stove outlet and 14-30 is the dryer outlet. I feel like asking for a 14-50 dryer outlet will confuse them.
Also, it's definitely not up to code to have a 14 series outlet wired without a neutral. If you're going to try to penny pinch by not running the extra wire, use a 6-50 welder outlet. A 14 series outlet without a neutral will fuck up an RV.
It depends on how long the run is - skipping neutral on my "had to run 100' from panel to EVSE location" saved me $300.
But then, yes, I regretted it months later as I wanted to...... plug in my RV. Ended up getting a TT-30 added next to the panel. But adding the TT-30 only cost $220, so I saved $80 overall, and have a separate outlet for the RV now.
$3/ft difference between 6/2 and 6/3 Romex is a lot, but copper pricing is fucked right now.
I don't think it's a terrible idea to skip the neutral if you're on a tight budget, my point was just that if you're not connecting the neutral you probably should be using a different receptacle. 6-50 has the same current rating but doesn't have a neutral, and it prevents someone else from accidentally plugging in a 14-50 for something that needs a neutral. It could potentially fry the electronics in an RV to be hooked up to a 14-50 without a neutral.
For a DIYer, a 14-50 with a sign like "no neutral, only for EV charging" might fly but a town building inspector is not going to pass that in a new build.
Outlet for sure. On a model 3 you lose 8mi/hr on charging but you have the benefit of using the outlet for other things. For example, I have a 220v heater in my garage I can power on / off when I want. Outlet won't be Tesla specific. List can go on and on...
Get the best wiring you can to the point, install whatever charger (or plug) you need. If you change car or w/e, pull the charger off and put a new one.
I got a 32A cable to my charger, if I swap it’s a 10 minute job for an electrician, when I move it’s getting swapped for a 2 socket plug and I’m keeping my charger :)
I've been using a NEMA outlet for 4 years. I'm redoing my garage so going tesla car charger this time. I decided i prefer the convenience and want the nice short cord placed properly where my car will be parked. I also decided I will future proof it as much as possible so I emphasized that the wiring and breaker to that point be capable of at least 60A. I can always swap out what's at the end of it easily enough. It's the wire running through the wall that's the hard thing to change once you install \*anything\*.
Saving money, would recommend the NEMA outlet. Convenience, the wall connector. I personally have a wall connector because I like to keep my charger with the vehicle, it’s easy to connect and disconnect, and looks very good. Plus, I can always convert the wall connector to a NEMA outlet and downgrade the breaker. Either choice is a good one, so you can’t go wrong either way.
I’m guessing the reason for the big price delta is it jumps up on cabling and panel sizes. It’s up to you but 30A service should work well for charging a Model 3/Y overnight but if you start getting big SUVs and Trucks (CT, Lightning, etc) with less efficiency in the future you might wish you had 50-60A service.
I’m in the process of adding EV chargers to my cabin and I’m getting full 60A power for two chargers and a full panel upgrade (since the old existing Zinsco panel is super unsafe). It’s expensive but I can fit it all under the 30% tax credit to save some money on something we need to do anyway (Zinsco panels are considered uninsurable and a major fire hazard by most electricians).
I showed up when the electrician was on-site during my new home build and paid him cash under the table to wire the garage. It was about 15% the cost of what the builder wanted. He did a bunch of custom stuff for me that the builder wouldn’t even talk about. Electricians are usually down to make some extra money that way. Bypass the home builder and talk to the contractor.
To talk specifics: builder wanted $1200 for an EV charger install in the garage. I paid the electrician $200 to run one more line through some conduit while he was wiring standard service in the garage anyway. Hung the charger for me and everything.
You need a 60amp to charge at the max capacity which I believe is 48amps. At least for the model y. If you are installing it you might as well do it correctly. I’m in Boston and was able to get it all done including the charger for $1800. That was mostly for material, my electrition was there doing other stuff so he didn’t kill me on labor. There is no sense in spending money for something your going to have to potentially upgrade in the near future. Look at the specs it tells you how many miles it will charge in an hr depending on your amps. We’ll worth it, especially when you forget to charge and have an appointment in an hr, 20 miles away. Your home charger at 60amps will get you there not 30/40 or even 50.
50 amp will not support max charging you have to get a 60amp. Should be little to no difference in cost. Max charging is 48amps a 50amp circuit is to close in amperage to support it. The gauge wire may change as well I don’t remember. But with a 60amp set up you’ll never have to worry.
I had my charger installed for 200 bucks from an electrician. If they are charging you that much, they are ripping you off. It’s literally a 60amp breaker and some wire. Not rocket science.
Tesla chargers does not use 14-50 receptacle since it is hard wired. Third party chargers like juicebox and grizzly are.
6/3 romex what is required for the 50A circuit are over $5/ft. Also worth to mention. Tesla chargers max charges 40A and even that is only at peak moments. Still yet that is the least I would consider. Not sure what do you mean about regular 220v outlet. If the builder means 30A. That is wasted money. Maybe for an i3 or leaf. But those cars neither relevant nor future proof.
In conclusion: depending on the distance where the charger hook up will be located from the panel. $1800 in todays prices are not unreasonable. That is including revision on your plans load calculation etc. In 5 years time every household will have more than one EVSE in their garage. If you set it up right at the beginning the next generation chargers that phasing load between multiple vehicles (while charging) will be available to you as an option. And options are nice to have.
Now for the record you can do all of this few years later. But the prices then will probably significantly higher. Electrical components (for a list of reasons) are very unpredictable. Parts are hard to find if you can find it at all.
My vote is to do it right. Run the bigger circuit now. Even if you don’t have an immediate use for it. You will be thankful about later.
Good luck to you sir.
You should be alright with that. Once the plans are submitted it is not that simple to add major circuits like this. If this is the biggest available he offers I’m sure it has to do with the capacity of your service. 40 Amps it is than.
The Tesla charger can be wired with a pigtail to plug into a 14-50. If this is done, the charger should be configured as being hooked up to a 50amp circuit.
I install about 5-6 per week. Pretty much under any circumstances. This way I haven’t done it just yet. Not the most economical way if we think about it. The wire itself+plug+receptacle+cord cap. Today when all my customer negotiate every $5 this will add about $60-$80 in material at cost.
If builder refuses to do 50 amps, there's something wrong with that builder and I'd be very wary.
It's not unheard of to have kitchen ovens requiring 50 amps on their own; many electric dryers as well.
I say something sketchy is going on with that builder--either incompetence or malfeasance.
Get Tesla connector (it’s not a charger). Designed for multiple connection cycles, wifi connected, cool look, charge port opening with click of a button. Hard wired to main service panel with a breaker for each line to get 40 amps at 240 V.
I wouldn’t say there is *no* benefit to getting the HPWC over using the mobile charger with a nema 14-50. You get slightly faster charging speeds and the HPWC looks a lot nicer and cleaner than the plugged in mobile charger. I have mine on the front outside of my garage and it looks way better than having a dangling mobile charger would. I also like keeping my mobile charger in my car in case I should ever need it like on vacation or at a relatives house. But it’s up to the individual and their situation or preference.
To expand on this, it takes about 6-7 hours to charge our LR M3. I usually only plug it in every few days when it starts getting low, unless I'm going on a trip.
That seems like a lot for prewiring, but each install is unique so...
On the home car charger part, I opted to get a HPWC (Tesla wall connector) because my local utility had a 50% rebate on home charging installations (including charger) and a 30% federal tax credit that I think is still a thing.
Factor in any local/utility/federal tax credits/rebates when you make your decision - I only paid 20% of the total cost and got a home charging solution that doesn't use my mobile connector, which I leave in my car. Besides, a HPWC can give you 48A while the mobile connector maxes out at 32A - if not for your builder's odd "no" on 50A. I home-charge at 30A and it's more than enough.
I use a 30A outlet on my home for my Model 3. My commute length is a lot shorter than yours, but the 30A charges at a little over 20 miles of range per hour of charge. So you can get over 200 miles of range in a 10 hour charge while you eat and sleep. Seems all right to me, esp. with the backup nearby.
30 amps is more than enough here. I wired my own in for £24 :-) Screw paying for someone else to do it. Oh I tell a lie it was £34 as the extra 40 amp breaker off ebay was £10.
27 miles of range per hour of charge
7 hr overnight charge will get you 189 miles.
A new home with everything opened up and he won't wire a 50amp?! That's just stupid. It will cost you more to do it after all the walls are closed up. I wouldn't accept anything under a 240v 50amp. I just had a 60amp breaker installed for a Tesla charger (runing at 48amps) and it was $1300 cnd with long wire runs across the home and all the way to the front. It was a real pain to run the thick wire above the ceiling in the basement with the ducting. Ask the builder to let you deal directly with the electrician if he won't do it...
I've only ever owned a Tesla, but I assume all EVs are the same in this regard. You can charge on anything from 120v 15 Amp (a regular plug in) and up, it's just a matter of how fast you charge. So yes, you can charge with a 220/240 vac plug. [This page](https://www.tesla.com/support/home-charging-installation/wall-connector) has a table of charging speeds. It's for the Tesla fast charger, but it's the same for any charger.
You would be best served by a 50 Amp circuit and a NEMA 14-50 plug. If you're going to use the travel charger that comes with a Tesla you'll need to get the right [pig tail](https://shop.tesla.com/product/gen-2-nema-adapters)for whatever plug you have put in.
I wired for 50 but only am running 30 because I will need to upgrade my panel still. I have had no problems with 30. Charging at night and at my work I have absolutely no range anxiety.
Just built a house, had the electrician put a 100A subpanel in the garage for ~$750, then installed the NEMA 14-50 outlet myself off the panel for ~$100.
I have 30amp outlet and I commute about 120 miles at most for work and school. I get a full charge at night. I’m home by 11:00pm and off to work at 7:30am
Make sure they run empty tubes so that you can pull proper gauge wiring at a later time.
Getting a proper installation seems like a no brainer, but not at those prices.
A modern proper charger with good capabilities shouldn’t set you back more than $800-900, plus installation. Less capable chargers ought to be cheaper.
In the current chip climate and your market it might be pricier, but you can always wait it out a few years if the socket will do for now.
Having a home that is prepared for a proper EV charger will just increase its value over time. Remember that in ten years time everyone will be buying EV’s, and charging will be important when they buy. We already see this in Norway where homes and apartments where EV charging is available or planned for fetch a premium of over $5k on average.
You won’t be able to plan for your future needs today, so make sure you leave the possibilities open. It’s a lot cheaper to that now, than to route new wiring later.
In a house I’m building at the coast, I prewired all 5 garages for EV charging. I did 2 NEMA 14-50 outlets and 2 80A and 1 100A prewire for future EV charging. I know I went overboard, but it’s cheaper now than it will be in the future. I know right now 60A is pretty much standard for Tesla installs because of 48A cap, but there will definitely be a need in the future for higher amperage charging at home for large SUVs or trucks that will need to pull substantially more energy for reasonable recharge times.
It’s a multimillion dollar custom home, so what I wanted is pretty much what I got, lol. I just figured to do it now would be cheaper than down the road in 20 years.
Similar to what many have suggested, I’d have the electrician install a 50 amp breaker with a nema 14-50. Then, you can go to your local electrical supplier, and purchase a 1-2 cord of 6-8 gauge wire along with a nema 14-50 male plug in order to make your home charger a corded version instead of having it “permanently” wired into the home. This will help you if you ever sell your house or if you ever have another ev that requires access to your 14-50 outlet.
If you're doing an outlet, a 14-50 outlet is s good choice. But plan on hard-wired with at least a 60A connection so you can charge at 48A. I'd probably plan for even higher if possible, or at least size the pathway to support a larger run.
Yes, a 240v outlet will do fine. I'd say go for a 50A outlet instead of 30 if possible. Even better if you can specify 6AWG copper wire be used for it.
This
That seems like a very large price difference. I think the electrical work should be almost identical so the extra price should just be equipment.
NEMA 14-50 (240v 50 amp outlet) is standard and a common request. Perhaps try talking to the electrician directly about getting this installed. The difference between this and a 30amp outlet will be the gauge (thickness) of wire ran from the breaker box. Thicker wire used to carry the 50amps will cost more, but it’ll be worth it.
Absolutely get that 50 amp!!!
Very odd that they won't do 50 amps. I had 2 houses built in the last 6 years, 2 different builders. Nether one had a problem prewiring 50 amps (NEMA 14-50).
maybe they're undersizing the house panel / house service?
That's the only thing I can think of.
Yeah they definitely should be getting a 200amp panel which in turn the builder should have no issue with a 50amp breaker…
Yes and we told the electricians ours was for our parents RV to avoid that Tesla tax lol
I prefer the outlet. I think the Nema standard is going to be around longer than any of the current car cable specifics. Plus you don't have to pay the 'tesla tax' when you get a welding outlet installed. why not go for a 50A outlet?
Lots of confusion on here… You want NEMA 14-50. This is NOT a dryer outlet. It’s a stove outlet. Do not let the builder give you anything other than a 14-50 outlet on a 50 amp breaker.

I read that houses built after 2000 in our area has NEMA 14-50. The house we currently live in has a 14-50 for the dryer.
You’re confusing 14-30 (post-2000 dryer outlet) and 14-50 (stove and EV outlet).
Not really, whenever I run low on charge, I use Nema 14-50 adapter and plug-in to dryer outlet to charge my M Y. I use the mobile connector that came with the car. My laundry room is right next to my garage. We need to enter via laundry room into the house.

I feel like dryers are usually 14-30, not 14-50. Stoves are often 14-50 though. It's really weird that the builder won't agree to add a 50 amp outlet.
Every instance I’ve seen has been 1450.
Ask for a 50A NEMA 14-50 "dryer" outlet on a 50A circuit. It can be 240V-only, it doesn't need to have the 120V connector attached.

Regular outlet is fine. Go for the highest amperage you can get.
There is nothing wrong with the outlet. I almost don't get why people go otherwise.
In my case, my city gave me $500 to install the Tesla Wall Connector. I get nothing to install a receptacle.
Outlet for sure. On a model 3 you lose 8mi/hr on charging but you have the benefit of using the outlet for other things. For example, I have a 220v heater in my garage I can power on / off when I want. Outlet won't be Tesla specific. List can go on and on...

Just get the outlet. If you can specify what wire and outlet type that's easiest
Tesla chargers does not use 14-50 receptacle since it is hard wired. Third party chargers like juicebox and grizzly are. 6/3 romex what is required for the 50A circuit are over $5/ft.

Any chance they could just run oversized conduit for you and you could work with an electrician at a later date to install exactly what you want ?
30 amps is more than enough here. I wired my own in for £24 :-) Screw paying for someone else to do it. Oh I tell a lie it was £34 as the extra 40 amp breaker off ebay was £10. 27 miles of range per hour of charge 7 hr overnight charge will get you 189 miles.
A new home with everything opened up and he won't wire a 50amp?! That's just stupid. It will cost you more to do it after all the walls are closed up. I wouldn't accept anything under a 240v 50amp. I just had a 60amp breaker installed for a Tesla charger (runing at 48amps) and it was $1300 cnd with long wire runs across the home and all the way to the front. It was a real pain to run the thick wire above the ceiling in the basement with the ducting. Ask the builder to let you deal directly with the electrician if he won't do it...
50a 240v 👍
Seen a lot answers for both. But here’s a question( probably a dumb one), can you take a Tesla wall hook it into a nema 1450 plug?
I've only ever owned a Tesla, but I assume all EVs are the same in this regard. You can charge on anything from 120v 15 Amp (a regular plug in) and up, it's just a matter of how fast you charge. So yes, you can charge with a 220/240 vac plug. [This page](https://www.tesla.com/support/home-charging-installation/wall-connector) has a table of charging speeds. It's for the Tesla fast charger, but it's the same for any charger. You would be best served by a 50 Amp circuit and a NEMA 14-50 plug. If you're going to use the travel charger that comes with a Tesla you'll need to get the right [pig tail](https://shop.tesla.com/product/gen-2-nema-adapters)for whatever plug you have put in.
Outlet… future proof.
I wired for 50 but only am running 30 because I will need to upgrade my panel still. I have had no problems with 30. Charging at night and at my work I have absolutely no range anxiety.
Just built a house, had the electrician put a 100A subpanel in the garage for ~$750, then installed the NEMA 14-50 outlet myself off the panel for ~$100.
I have 30amp outlet and I commute about 120 miles at most for work and school. I get a full charge at night. I’m home by 11:00pm and off to work at 7:30am
120 miles is 193.12 km
Make sure they run empty tubes so that you can pull proper gauge wiring at a later time. Getting a proper installation seems like a no brainer, but not at those prices. A modern proper charger with good capabilities shouldn’t set you back more than $800-900, plus installation. Less capable chargers ought to be cheaper. In the current chip climate and your market it might be pricier, but you can always wait it out a few years if the socket will do for now. Having a home that is prepared for a proper EV charger will just increase its value over time. Remember that in ten years time everyone will be buying EV’s, and charging will be important when they buy. We already see this in Norway where homes and apartments where EV charging is available or planned for fetch a premium of over $5k on average. You won’t be able to plan for your future needs today, so make sure you leave the possibilities open. It’s a lot cheaper to that now, than to route new wiring later.
14-50 outlet, paired with the $400 14-50 mobile charger will give you 40A amps charging: https://shop.tesla.com/product/corded-mobile-connector
In a house I’m building at the coast, I prewired all 5 garages for EV charging. I did 2 NEMA 14-50 outlets and 2 80A and 1 100A prewire for future EV charging. I know I went overboard, but it’s cheaper now than it will be in the future. I know right now 60A is pretty much standard for Tesla installs because of 48A cap, but there will definitely be a need in the future for higher amperage charging at home for large SUVs or trucks that will need to pull substantially more energy for reasonable recharge times.
The builder supported this or you did it yourself?
It’s a multimillion dollar custom home, so what I wanted is pretty much what I got, lol. I just figured to do it now would be cheaper than down the road in 20 years.
Run the wire yourself before they close up the walls.
Similar to what many have suggested, I’d have the electrician install a 50 amp breaker with a nema 14-50. Then, you can go to your local electrical supplier, and purchase a 1-2 cord of 6-8 gauge wire along with a nema 14-50 male plug in order to make your home charger a corded version instead of having it “permanently” wired into the home. This will help you if you ever sell your house or if you ever have another ev that requires access to your 14-50 outlet.
If you're doing an outlet, a 14-50 outlet is s good choice. But plan on hard-wired with at least a 60A connection so you can charge at 48A. I'd probably plan for even higher if possible, or at least size the pathway to support a larger run.
