Indeed. I would not have noticed the discoloration on the Levition because I rarely disconnect it until we got into the discussion and it was pointed out. It is a bit concerning so I am changing both of them.
you should get a hubble for one - and the leviton for the other - and give us feedback as to if there is difference(s) over time or initially

you're in a unique position to test both of these at once!!

so here is my proposed order. Price difference is interesting. (CND dollars)

looks good - I'll be very very interested in your feedback comparing the new sockets head to head…I think it will be a great contribution to the EV community if we learn first hand that both sockets are an equally good choice, or one stands out vs. the other as either better or worse…

thanks for doing this!

in both cases I think either/both of these sockets are a higher quality upgrade vs. your current Leviton sockets in your garage.

I agree - I found it whlie looking on amazon to give you @shawn a link for purchase ;-)

would not have found it if it was not for you!!!

I love this!! we're all learning as we go and new information is happening!!

I love this.
Got the first one in (the Lveviton) just waiting for the Hubbell. I had a look at the CB pannel for the two separate circuits and they both have 40 amp breakers. I was a bit surprised as I thought they would be 50 amp breakers. I will ask the Electrician when the Hubbell comes in.

40 amp breakers and associated wire should only support 32 amps of EV charging…

_IF_ the wire gauge is appropriate you can swap the breaker to 50 pretty easily - but mostly breaker size and wire gauge is what building codes are mandating/managing - the breaker trips before enough current has run through the wire to compromise the wire…

so depending on local building codes your wire may support 50 amp breakers - if not it's more expensive to re-pull new wire for a 50 amp circuit.

NOTE: _ANY_ hardwired EVSE in North America can be "converted" to a plug based EVSE with this cord from amazon (or similar) - this cord is rated for 50 amps - it's 4 wire, so you just won't use the white/neutral wire.

Max allowed circuit size for _ANY_ NEMA plug-based EVSE in North America is 50 amp circuit breaker - 40 amp charge rate - EVSE's running at greater than 50/40 amps MUST be hardwired as-per 99.9% of building code regulations - therefore _IF_ you're going to install a "hardwired" EVSE and use a cord like this one (or similar) then you MUST limit your EVSE to 50/40 amps (9.6 kW max charge rate).

the cord linked in this posting is a NEMA 14-50 plug-cable - 4 wires - 2 hots, 1 neutral, 1 ground - Neutrals are un-necessary/unused with North American EVSE's. (there is not even a place to attach/connect a neutral wire inside of any hardwired EVSE I've ever installed - so you just push the white/neutral wire aside inside the EVSE box and put a wire nut on it) - so you can simply ignore/wire-nut the "white/neutral" wire and only wire up the 2 hots and 1 ground inside your EVSE

_OR_

you can find a similar cable for a NEMA 6-50 outlet and then use a NEMA 6-50 outlet and have a "matching" 3 wire cable for your 3 wire EVSE plugged into your 3-wire NEMA 6-50 outlet

there is nothing "magic" about a plug based or hardwired EVSE - with plug-based EVSE one end of the 3/4 wires is "molded" into a "plug" and the wires soldered/connected to plug-blades and encased in plastic…

in fact if you order a plug-based EVSE from enphase/clipper-creek/ChargePoint, I promise you it _IS_ a hardwired unit where they simply pre-attached a cable just like this one before they put it in the box…so a hardwired EVSE vs a plug-based EVSE in most cases is simply a matter of did the vendor go ahead and attached a cable exactly like this before shipping it to you - there is nothing "magic" here. Hardwired EVSE's just do not ship with one of these cables (much like most 240V home appliances where they leave this part as an exercise for the reader/installers).

recommend the 10 ft version - YMMV - don't take electrical advice from the internet - you're on your own if you follow this advice and things go sideways.

NOTE: one of my 3 Tesla Universal Wall Chargers is wired to a Hubble NEMA 14-50 using this exact cable - it was easy and has worked well since Oct. of 2023 - YMMV - hire an electrician if you are the slightest bit uncomfortable and let them make all the decisions.

the cable listed below has the following:
  • red wire - 6 AWG copper wire - 120V hot - overkill/overspec for 50 amp applications
  • black wire - 6 AWG copper wire - 120V hot - overkill/overspec for 50 amp applications
  • white wire - 8 AWG copper wire - electrical neutral - _UNUSED_ in EVSE wire diagrams - will be inert and never carry any electrical current - it does not matter - 8 AWG wire is good as a neutral for 50 amp applications - but again it's not used in this case!!
  • green wire - 8 AWG copper wire - electrical ground - overkill/overspec for 50 amp applications
when I wired up my Tesla Universal wall charger the hardest part of the install was carefully stripping back the thick/heavy-duty black rubber insulation from the "bare wire" end of the cable to give myself a little more length for the red/black/white/green wires to bend/feed them around the inside of the Tesla Wall charger dock (I had to free up about 20 inches of the 4 wires to nicely fit/bend inside the Wall charger dock) - so you'll need to trim back the thick heavy duty black rubber insulation to give yourself more working length of wire to attach it inside most EVSE's - this why I recommend the 10 ft version of this cable to give yourself plenty of length since you may want to trim the cable length to "fit" your particular install - trimming back the black insulation is actually the hardest part of this entire process - as you have to be careful to remove the black insulation but not also strip the insulation on the individual wires!!! This is the most time consuming and tedious part of using a cable like this - after you freed up enough length for inside the EVSE box/dock - the rest of the install is nearly trivial.

NOTE: each of the 4 bare wires corresponds to one of the metal "blades" on/in the plug head - I've labeled the blades in the picture below to match the wire color coming out the other end - red and black might be wrong - but it doesn't matter - both are 120V hot and 100% interchangeable in electrical 240V applications (it honestly makes NO difference) - green is ground, white is neutral - ground pin is at the 12 o'clock position on the plug head, and neutral (unused) is at the 6 o'clock position (but again unused in any EVSE install/scenario).

the goal of this post is NOT to make you install your own EVSE using a 50 amp prefabricated NEMA 14-50 appliance cable - it's to demystify this stuff and show people that it's actually pretty simple how this stuff works - 3 wires, and some simple wiring and you have an EVSE.

there are similar pre-fabricated cords for most _ANY_ North American NEMA socket - so you can do the exact same thing for 15, 20, and 30 amp NEMA outlets (the proper NEMA socket for a 40 amp circuit happens to be a NEMA 14-50/6-50 - this is apparently allowed since there is no explicit 40 amp NEMA socket)

so if you want to install _ANY_ EVSE for any circuit breaker size but have it be plugged based - simply use the correct NEMA socket - and purchase a pre-fabricated appliance cable and wire up the 3 wires (ignoring the 4th wire if your cable has it).

you can hook up your Tesla Wall Charger or ChargePoint Flex to your dryer outlet (30 amps) and set them to 30 amp breaker and use a dryer appliance cable for NEMA 14-30 or 6-30 for example…easy peasy.

This topic comes up occasionally and is a source of confusion for many new EV/Hybrid owners. My goal with this FAQ is to cover the difference between NEMA 14-50 and 6-50 and allay any fears one might have about making this choice.

Question: Is there any Functional difference between installing a NEMA 14-50 and 6-50 outlet?
Answer: if the sole purpose of this outlet is for EV charging then there is no functional difference. Both outlets are North American standard(s) for a 240V/50 amp circuit. In both cases an appropriate EVSE will charge an EV at 9.6 kW - or 240V @ 40 amps - the maximum possible electrical current for a plug-based device in North American. Charging "speed" is identical for NEMA 14-50 and 6-50 outlets - so honestly it's a coin toss as to which one you want.

Question: if there is no difference then why choose?
Answer: Multiple plug types exist for multiple reasons. There is a functional difference between NEMA 14-50 and 6-50 in that the 14-50 outlet has a 4th connector/blade for an electrical neutral wire. This neutral is 100% required if you wish to use one of the 240V "legs" of the socket for 120V device/outlet. This is why NEMA 14-50 is used by RV's for traveling. The campground NEMA 14-50 outlets can provide an RV with 50 amps of both 240V/120V power. The RV are typically setup for the 240V portion of the outlet powering like an AC unit/Oven in the RV, and the 120V portal of the NEMA 14-50 providing normal 120V North American household outlets for TV's, computers, and Microwave, Toasters etc…. North American EVSE's do not use or require an electrical neutral - so they can interoperate with a NEMA 14-50 outlet or NEMA 6-50 outlet.


Further Note - the two 240V/L2 AC charging standard plugs (NACS/J-1772) also have no requirement or accommodation for an electrical neutral. There are 5 electrical connections inside a NACS/J-1772 EV plug connector - 2 high voltage, 2 low voltage communication, 1 electrical ground - if there was a need for an electrical neutral there would have to be a 6th pin/connector inside the plug design - and there is not - for 240V L2 charging there is no actual method/mechanism to provide an electrical neutral to the vehicle itself - so the 4th wire is 100% unused in North American EV charging electronics/design/specification. see here for gory details

Question: If there is no difference then why would an EVSE come with one plug or the other?
Answer: Ease of use. If you want your customer purchase a vehicle from you and when they get home simply plug-in to charge - it's important to provide an EVSE that is most likely "compatible" with exiting plugs the customers are likely to have. If you have to 'guess' what type of plug people have, I have to say it's more likely to find an existing NEMA 14-50 socket in someone's home vs. a 6-50 outlet. But it's purely a probability guess to get with NEMA 14-50 as a default choice. Early EV vendors provide a NEMA 14-50 for reasons listed above, but their choice further reinforced the default choice of NEMA 14-50 - such that as other vendors entered the EV market NEMA 14-50 was the best "default" choice because other EV's also used NEMA 14-50 - the whole thing was/is a self reinforcing virtuous cycle - and it's still the case today that there are more NEMA 14-50 sockets "in the wild" so it's still a great choice - but it was a guess by the early guys that became a more reasonable guess over time.

Question: if NEMA 14-50 was so dominant a option then why NEMA 6-50
Answer: NEMA 14-50 was the majority, but not the entirety of 240V/50 amp circuit landscape in North America. There is a small but significant "installed" based of NEMA 6-50 (and to a lesser extent 10-50) outlets. A common location for NEMA 6-50 outlet is actually auto and truck mechanic's shops since NEMA 6-50 is used for industrial arc-welders, and in a industry/home setting for oven/kilns - so while there are more NEMA 14-50 sockets given their usage by RV/Motorhomes/Campers - NEMA 6-50 was common enough for 240V industrial equipment - you know the stuff for which compatibility with 120V isn't a consideration. Given that both exist in sufficient quantities EVSE vendors tend to offer both 14-50 and 6-50 support and both are equally good choices for 9.6 kW charge rate.

think about this for a moment and remember it when you read later about using high quality copper wire and commercial grade industrial sockets - your new EV will be pulling the same amount of power needed for an industrial arc-welder - and it will continuously pull this amount of power until you reach you set charge level - if your EV is near empty when you plug it in - you're pulling arc-welder amounts of power for 6-12 hours continuously until the battery is "full" - quality materials are required to avoid problems.

Question: I own an RV and often park it at home but I also want to get an EVSE outlet - which should I choose?
Answer: Most likely the NEMA 14-50 if the socket is to be "dual purpose". If the socket is going to be used for both EV charging and RV power "hook up" then NEMA 14-50 is probably the better choice since a Motorhome/RV "requires" a NEMA 14-50

Question: If NEMA 14-50 is more "flexible" (i.e. having the neutral) why would I consider a NEMA 6-50 outlet?
Answer: NEMA 14-50 outlets require 4 wires (2 hots, 1 Neutral, 1 ground). NEMA 6-50 require 3 wires (2 hots, 1 ground). With the price of thick gauge high-quality copper wire, depending on the distance/length of your wire run for your EV charging NEMA socket from the breaker there could be actual real and significant savings in terms of materials cost for your EVSE circuit installation in terms of pulling 3 wires vs. 4 wires. Consult your electrician as to actual potential savings.

Question: If I get a NEMA 6-50 socket installed and later on want to change to a "hard wired" wall mounted EVSE is there a problem if I'm missing the 4th (electrical neutral) wire?
Answer: As of the date of this posting I'm unaware of any hardwired EVSE's that require an electrical neutral. Of the top 5 choices (Tesla Universal, Charge Point Flex, Porsche Wall Charger, Wallbox, Enphase/Clippercreek) their hardwired EVSE's all only require 3 wires. If you had pulled a 4th wire (electrical neutral) it would simply be unused by the EVSE and you'd simply put a wire cap on it and push it aside in the installation.

Question: Wow this is super confusing if there is no difference and I don't own an RV why would I care?
Answer: The decision about which plug to source for your EVSE (it's a $0 choice at order time w/Porsche) comes down to "compatibility". If you already have a NEMA 14-50 installed, then clearly the simplest choice is NEMA 14-50. If you already have a 6-50 socket installed then get a NEMA 6-50 power supply cable with your EVSE. For purposed of at home charging overnight the decision does not matter. You simple purchase/source/provision what ever type of socket you already have or will have installed.

Question: If I don't care what type of plug I have for home charging, then why would I ever care?
Answer: This is where there is a main difference between NEMA 14-50 and 6-50. The main reason you might care is for when you are traveling away from home and wish to carry your EVSE with you (for a mobile EVSE). To understand why NEMA 14-50 became the "default" choice from most EV vendors for their mobile EVSE it comes down to "installed" based of existing 240V/50 amp outlets in all of North America. For home use the socket type does not matter, because you simply match your EVSE to your socket. It only for travel that you might care. When you are away from home with your shiny new EV and your Mobile EVSE you are far more likely to encounter a NEMA 14-50 socket in the wild vs. 6-50. It's simply a matter of existing "installed" based - there are way way way more NEMA 14-50 outlets than 6-50 outlets. So it''s just easier to have a NEMA 14-50 EVSE which works at home with a NEMA 14-50 outlet and works away from home for outlets you encounter in your travels. This was more important in 2011-2015 than it is today. There are far more commercial EVSE (fast & slow) that you are likely to use vs. using a bare NEMA 14-50/6-50 outlet, so the need for one to have a "compatible" mobile EVSE with the "right" plug is greatly reduced. I'd venture that unless you have a specific location in mind (a family/friends cabin on the lake for example) you're more likely to need a spare tire these days vs. a mobile EVSE w/NEMA 14-50 outlet.
Question: if my EVSE is not mobile which should I get?
Answer: Do what ever is cheapest/easiest for you. Non-mobile EVSE's can be purchased with NEMA 14-50, 6-50, or hardwired. If it's a wall mounted EVSE it honestly does not matter which one you get. If you're installing "new" I'd recommend a quality 60 amp "hardwired" unit vs. any 50 amp plug based unit. If you already have either a NEMA 14-50/6-50 outlet then obviously choosing an EVSE for your existing plug is the path of least resistance and cost.

Question: If get a 6-50 plug for home to save myself some 💰 how do I use NEMA 14-50 outlets when I'm traveling?
Answer: Most (nearly all) mobile EVSE's allow you to purchase/swap additional NEMA plug outlet cables. Porsche's own mobile EVSE has swappable power supply cables for different types of NEMA outlets as do most non-porsche alternatives. In addition to directly supporting swappable cables there are affordable adapters for various NEMA plugs as well that you can easily purchase and carry with you. The whole issue of road tripping an EV and having "maximum" away from home power to charge any place, any time, any where, any NEMA socket is a whole rabbit hole that is well covered by this existing thread. For the most part in 2024 and beyond the need to carry your own mobile EVSE is greatly diminished and utilization when out in the wild will be very very low vs. just using someone else's commercial EVSE that is already installed. But rest assured your home choice of a NEMA 6-50 vs. 14-50 outlet will not "lock" you in, there are easy and affordable options to allow you to charge when away from home.

Question: I'm new to the EV world and this is my first EV charging setup, what should I do?
Answer: I can't speak to your budget or goals, but a good/excellent home charging setup is one of life's little joys in EV ownership. I'd worry less about the mobile charging aspect and more about the convenience of home charging. A good solid and well installed hardwired unit on the biggest AMP circuit you can afford will be the best path forward. Should you need a mobile EVSE for traveling away from home you can always engage in that later and get what you need for away from home charging. My prediction is you won't need a mobile EVSE very often and instead will use other people's EV chargers and in particular FastDC charging like Electrify American, Superchargers, EvGo, ChargePoint.

Question: Why would I get a NEMA 6-50 outlet?
Answer: You may save significant money on your install materials cost by pulling only 3 wires vs. 4 wires - consult your electrician for potential actual savings.

Question: My wire run is fairly short? should I still get a NEMA 6-50 outlet?
Answer: NEMA 14-50 is "more" flexible in that it will work for both EVSE's and potentially an RV - if there is no significant difference in cost I still prefer the NEMA 14-50 outlet as the more "universal" choice. But there is no functional difference for purposes of EV charging.

Question: Why not just hardwire?
Answer: Excellent question and these days I'm trending towards hardwired EVSE's and ignoring the plug-based mobile EVSE's all together. Hardwired EVSE also give you greater freedom to get an EVSE that can charge your eV faster than the limited of 50 amp mobile EVSEs. There is no problem getting a hardwired EVSE and simply using that, but most people wish to avoid the additional cost if their EV purchase has an included mobile EVSE. That being said my recommendation is simply avoid the mobile EVSE and simply get a high quality wall mounted EVSE hardwired on a 60/80/100 amp circuit if possible and you'll be set for current and future needs. You can tuck the mobile EVSE away for when you sell/trade the car, or carry it with you for your travels - although I doubt you'll use it very often.

Question: I'm now super confused and this thread has done nothing to clarify anything for me - what should I do?
Answer: You can ignore all of this and simply follow the EV charging instructions from the dealer/vendor that sold you your EV. This thread was an attempt to offer insight and some background, if I have failed my apologies. For the most part following vendor/dealer instructions will be fine and you don't need to understand any of this. However a little knowledge is sometimes useful and if you understand what's discussed in this thread you may be able to plan your home charging and mobile charging setup with an eye for the future (this is your first EV not your last EV) and avoid doing the whole "let's setup my garage for my new EV" multiple times. A little knowledge, planning and your EVSE home charging setup can be a do it once and never do it again affair - even as you change EV's.

Question: I plan to get a NEMA 14-50 or 6-50 socket, what should I ask my electrician?
Answer: 50/40 amp charger @ 240V/50 amps is no joke in terms of power, heat, and stress. The highest quality components should be required/demanded. CopperWire (over-spec if possible, if building code calls for 8 gauge, you can request 4 or 6 gauge wire) and the highest quality commercial outlet - which is the Hubble Commercial grade outlets - don't believe me then believe Porsche at this document. It can take 8-11 hours to charge a Macan from empty - that is a lot of power and a lot of thermal energy from charging - don't wimp out on your home charging install - that's the last place you want to cut corners.

Question: I've read all this and still don't know what to do.
Answer: Get a Hubble NEMA 14-50 installed and you'll be fine - you can ignore this entire post.

Question: I have an existing NEMA 14-50/6-50 socket - do I need to do anything?
Answer: Yes you need to verify it's a commercial grade/industrial socket like the Hubble (or exactly the Hubble). If it's not industrial/commercial grade it is highly recommended you swap the existing plug for one of the high quality industrial alternative sockets that Porsche (and the rest of the EV industry) recommend/require. 14 year old dusty $12 Leviton NEMA 14-50 sockets from Home Depot are not what you want charging your $120k Macan EV Turbo over night for 8-9 hours.

I'll add more Q/A when I think of it or requested - but that's it for now.

for home charging recommendations I recommend the following existing Taycan thread for new Macan EV owners…

NEMA 10-50 is yet another NEMA plug type for 240V 50 amp circuit -but it's still only 3 wires and fundamentally identical to NEMA 6-50 outlet - since both are 3 wire affairs its easy to covert an existing 10-50 outlet to 6-50 outlet, or just buy an adapter - at the end of the day they are functionally identical but with a different "blade" pattern - there is no difference electrically in terms of circuit capacity - just the shape of the plug & socket…

NEMA 10-50 shown below…3 wires - 2 hots and ground -240V - 50 amps capacity - just more of the same in a slightly different package.

any thoughts on comparing the two different outlets?
Both are installed and both work as expected. The Hubbell looked slightly more robust but the other was very similar. I just left the original circuits as they were so I have two separate 40amp circuits. Charge time is slow but good enough for overnight charging and I have only ever charged one at a time although I suppose I could charge both simultaneously if I needed to. The old Leveton that was removed looked pretty cheap and discoloured by comparison so I am glad I replaced it.

I appreciate the update - so you'd say one or the other is equally good and recommend both with out reservation?

Yes both are good and solid choices. Of course I would not recommend the standard dryer outlet I had before as the difference is very noticeable. it seemed like the electrian took note as well so so he won’t be using that for future EV installations 😏

It seems like at least in my case the two or three electricians I spoke with did not pick up on the difference of a standard dryer plug and one that is more appropriate for EV‘s, They insist that they all are equal but clearly they are not. The new Leviton with the EV picture is there because the manufacturer designed it for this purpose and you can tell the materials are different. I think people including electrians need more product knowledge in this area.
