Leviton announced the introduction of the first 40 Amp Electric Vehicle Charge Connector Assembly – J1772.

We are not sure what exactly is new in such connector, as Leviton itself already was selling an EVSE rated for 40 A. Some other vendors have even higher amps EVSEs. However it’s good that Leviton is broadening its offer for EVSE rated up to 9.7 kW.

This connector assembly is presumably more targeted at aftermarket applications, as it only includes the connector and cable, not the actual EVSE or charging station.  Or perhaps it’s for replacing a damaged connector/cable assembly?

However, very few vehicles are equipped with a 40A charger – the Toyota RAV4 EV falls out of the market soon and other models don’t have high-power on-board chargers (Tesla has it own EVSE with a different connector).

So, the question is if there will be more models with 9.6 kW on-board chargers any time soon to leverage sales of such a connector assembly? Anyways, when the new generation of EVs appear on the market capable of handling this power, Leviton will be ready.

“In order to abide by Leviton’s commitment to help create a sustainable environment, the Charge Connector Assembly utilizes an environmentally responsible and low carbon footprint connector housing. In instances of unauthorized use, a built-in anti-theft mechanism serves as protection. The connector assembly is available with 25 feet of flexible yet durable 8 awg electrical vehicle cable.”

“The Leviton 40 amp charge connector assembly meets or exceeds the stringent UL 2251 Plugs, Receptacles and Couplers for Electric Vehicles, UL 62 Flexible Cords and Cables and NEC 625 Electric Vehicle Charging System Equipment standards.”

“As the adoption of electric vehicles becomes more prevalent, an emerging trend is the utilization of larger on-board chargers, requiring charge connector assemblies with higher rated current capacity.  The Leviton 40 amp Connector Assembly is well-suited for the next generations of vehicles and charging stations.”

Manoj Karwa, Senior Director of EVSE Programs for Leviton’s Commercial and Industrial Business Unit said:

“We have worked closely with our automaker partners to develop a safe and reliable connector assembly that is designed for more than 10,000 operating cycles – that’s more than 27 years of use. The 40 amp charge connector assembly is in use in 3,000 dealers and in 11 different vehicle platforms as part of our 32 and 40 amp charging stations, creating a family of charging stations to meet the next generation of electric vehicles.”

AFAIK other than this cable, the larger L2 cables are rated for 30A or 75A typically, at least going by OpenEVSE vendors. Also AFAIK the i3 and B-class can take 40A, as well as the Model S.

Peak charging on i3 is 7.4kW (30A) but a software update now makes charging temperature dependent and may drop to 5kW (20A) depending on ambient conditions.

B-Class is 9.6kW (40A) since they use the same Tesla charger that’s in the Model S and RAV4 EV.

Gotta hand it to Tesla . . . they did their chargers very well. But that comes from them starting at the top of the market and then working their way down as the technology gets cheaper.

I think B-Class is 10kw (~30 miles per hour), and i3 is 7.7, or 7.4kw. So, there’s two able to use this. 25ft of 8ga “flexible” cable is also nice.


Info 1:
the BMW i3 cant use 7,4kw anymore. Its new software limits that to 5kw due to heat problems.

Info 2:
Renault ZOE is charging with 63A at 3-phases with 43kw for 2 years, so that 40A is something special, may be for USA.

Just FYI

Don’t install that one in a public place without a camera on it. Someone is going to steal the copper.

This cable is $299 at Leviton’s store and $220.68 on Amazon Prime. Quick Charge Power offers a 40A cable set that does the same thing, but offers a much thinner and more flexible cable for much less money. This is possible by using smaller parallel conductors for the power carrying wires – a strategy used by Tesla in their cables as well.

As battery sizes grow so will the need for larger capacity EVSEs and their cables. Looks like Leviton is getting ready for the future.

They started making this cable 2 years ago for their own product. I’m really wondering what prompted them to start selling it separately. The volume for OpenEVSE or JuiceBox is not that much and those are more price sensitive, so they would probably use a Chinese cable anyway.


I used the Leviton 30a cable to construct an OpenEVSE and it works great – very high quality component. I wouldn’t scrimp on cheap connectors. 240v can kill you quick, and it only takes once.

Meanwhile the 2008+ Tesla Roadster & 2012+ Model S support charging upto 80A (240V) using J1772 connector/adaptors.

Wonder how long it will take Levitin to introduce 50A, 60A, or 70A rated connectors? Manufacturing higher rated connectors is not rocket science!

At issue is it not easy to tell 15A (Blink de-rated), 30A, or 40A connectors apart. What if a replacement 30A connector is installed on a 40A EVSE. How would you know the connector was correctly matched for a given EVSE? It would seem standards J1772 standards committee has some work to do.

The difference is in the cable gauge and what the EVSE advertises via J1772 signaling. The connector’s the same. Of course, a lower-power-graded cable doesn’t need to be as low a gauge, so it’s fairly easy to tell a 12A L1 from a 30A L2, and even a 30A cable is more flexible and thinner than a 75A L2.

Agree. My comment was with some sarcasm as the title, first line of this article, plus Leviton’s own PR and video make specific callout to …

“Leviton announced the introduction of THE FIRST 40 Amp Electric Vehicle Charge Connector Assembly – J1772”

I see a 10 KW AC charge to be the ideal speed – give decent range at public chargers in a reasonable time frame.

For use at home – I would really like to see an EVSE unit that can be tied in with an energy monitoring system like eGauge or other energy monitors for solar – give the option to only draw power at up to the amount of solar energy being generated – but allow an override like when telling the Leaf to charge to 100% and ignore charge timers to allow a charge at the max rate possible.

I just got my 21 panel Solar array turned on yesterday – it’s quite interesting watching the energy monitoring when turning different household items on/off and also seeing the draw while charging my car – but I would love to say that I got a full charge from 100% solar without having to pull any power from the grid – not just looking at net metering, but outright 100% from rooftop solar.

Very interesting, I would note that the J1772 specification mandates a maximum cable length of less than 20 feet and components of similar quality and “UL” certified assemblies are available for only $140 I guess that Levithon name is worth an extra $100 to their customers. Oh,and the extra five feet of cable makes a good weapon to beat up the window washers who attack you at traffic lights.

Quick Charge Power has been offering the 40 amp J1772 cable / plug assembly in any length (20-25 feet is typical) before Leviton / ITT did. It’s also a lot cheaper, lighter, more flexible, and actually uses a 50 amp rated plug, plus the cable and all the assembly is built right here in the USA:


Leviton / ITT did offer a 75 amp cable, but that was cancelled about 2 years ago. Also, their 30 / 32 amp cable was also discontinued last year, and replaced with Yazaki brand cable that they still sell.

So, I don’t know if this 40 amp J1772 assembly is built by Leviton, or not. It’s definitely not the “first”.

I forgot to add that the 40 amp Quick Charge Power cable can also be configured with:

1) external timers
2) external power supply for optional built in lighting
3) confirmed for alarm system
4) external proximity disconnect

There are three dedicated communications wires (18-20 gauge) for the above, plus the required pilot signal.

Car that can use the capability of a 40 amp J1772 cable are:

1) Tesla Roadster (with “CAN” adaptor)
2) Tesla Model S / 3 / X (with Tesla supplied adaptor)
3) Toyota Rav4 EV (with Tesla onboard charger)
4) Mercedes B-Class ED (with Tesla onboard charger)

Of course, any other EV with a J1772 port can also use this plug.

Big deal over nothing.

Leviton then insists you purchase their ‘mounting kit’ which is about $60 overpriced and should have been included with the Leviton 400 in the first place.

Just another way to bilk the customer. Right up there in value with their $800 – 12 amp level 1 charger. Who would buy one of these things other than rich guys who had everything?

If this is so unique, how come last friday I used a 70 amp J1772 cable on the end of a SunCountryHighway EVSE that has been installed for months now?

Leviton is late to the party. I’ve been using the orange Dostar 50A cables for two years. Just added a Quick Charge Power super-flexible and thin 40A cable to a portable EVSE.
