This WOLFBOX 50 amp J1772 charger stands out as a basic but capable Level 2 home EVSE with a 25 foot cable, smart scheduling, and a plug or hardwired setup. The housing is bulky and visually awkward for indoor mounting, but the app is described as bare bones rather than complicated. Certification is the main concern, since it is CSA certified rather than UL certified, though the CSA label is also described as testing to UL standards. The 14 50 plug setup may need derating to 40 amps continuous, so hardwiring looks cleaner for full output.

  • The NEMA 14-50 configuration can be derated for continuous charging while still supporting practical installation options.

  • The charger can work as advertised while keeping the app limited to scheduling charging times.

  • The 50A version can be used for nearly two years with an excellent experience reported.

  • A J1772 extension can reportedly run with less than 1V voltage drop for this kind of setup.

  • The charger may require derating when using the NEMA plug for continuous charging.

  • The charger's bulky housing and cloud-connected approach may be undesirable for residential wall mounting.

  • The NEMA 14-50 version may not receive the same coupon discount as the hard-wired version.

  • The charger's certification status may be a concern because it is described as CSA certified but not UL certified.

if i ever need a electrician, i just come to SD. So many experts.
As an electrician that's been doing it 20+ years I approve of this message. It's always funny seeing people give terrible electrical advice on here. You're lucky if 1 out of 20 of them have any idea what they're talking about.

The housing on this thing is so bulky. I'd love to add an external charger outside of the garage, but this thing is huge and ugly.

Bulky for indoor too, but I think it's a good price for the capabilities.

I wouldn't trust the "cloud app" to work for more than a few years. These things need to work on a LAN.
You know what's not bulky? The $10/gallon fuel that's coming.
What kinda complaint is this? The option to avoid gasoline, and this is your mindset.

All things considered, putting a pigtail on this hard wire isn't complicated or dangerous if you don't take shortcuts. It isn't like creating a suicide cord or anything...leviton sells the plugs for like $25. A Bryant will cost quite a bit more. Your main issue after that is going to be dealing with double GFCI, since NEC now (as of a few years ago) requires the protection on the breaker end...and all EVSEs have their own protection already built into themselves. You'll get a lot of trips as they fight each other...but if you hardwire, this is a non issue (NEC drops the GFCI breaker requirement here) hence why hardwire is more popular now for new installs.
This is the truth right here. The nuisance trips are real, which can leave you with an uncharged vehicle in the morning when you wake up.

If you are staying within code, it's going to be better to hardwire it nowadays simply because these things absolutely hate GFCI circuits.

Recepticle has to be EV rated because they may melt under continuous load and start a fire. I don't see how it would be any other way for the plug.
I don't think it's so much that it needs to be EV rated but I'm pretty sure that NEMA 14-50 when hardwired can't exceed 40A continuous. I've never installed (and I've done a few) an EV charger that's got a plug that will go above it.

What are you going on about? This EVSE deal isn't going to persuade anyone to buy an EV, and every EV comes with one, albeit one that is designed to lay on the ground.

Yes, it's bulky, and probably one of the ugliest things to mount to a RESIDENTIAL building. There's no reason for this thing to be so large. There is no conversion happening in a Level 2 EVSE - it doesn't need to be nearly 2 feet tall, over a foot wide, and stick out of the wall a foot.

My factory EVSE is 2 inches thick and maxes out a NEMA 14-50 circuit. I'd like an exterior wall mount unit for visitors to use, but they don't need to be so big. Nor "cloud connected" of course - that's just planned obsolescence. I guess that's already a given with J1772 though.

Not all NEMA 14-50 recepticles are created equal though. Ones that are rated for 40A continuous load (which I referred as EV rated, as they are indicated by a car charging symbol on them) are more expensive and built to withstand the heat. A $12 Leviton 14-50 outlet definitely melts at some point.

I guess that's the point I was trying to make

How smart is this? Can you buy 2 for 2 cars and plug them both in and they manage to charge one and then the other or alternate them in a smart way?
I just started looking into this myself. What you want is a smart splitter. NeoCharge has a variety of options, but they're fairly pricey. Cheaper ones can be found.

Not UL certified. It is CSA certified, which is odd that they didn't also obtain the UL cert. Do what you want with that, but I'm not personally buying anything that can carry this much juice without the UL.
CSA certified to UL standards. CSA is a nationally recognized texting laboratory (NRTL) testing to UL standards .

Which is why I'm hesitant. There should be no reason not to obtain the UL if you can get the CSA. It seems kinda fishy.
Because thats not how it works.

UL does 2 things.
1- write a test standard
2 - perform testing

A few years back, there was some major concern with the electric code requiring a private company (UL) to test stuff. So, they made a deal. UL would publish the test specs as a non-profit action and perform the testing as a profit action. Other companies, if properly recognized, would test to the same standard.

ETL and CSA perform the same test as UL, but frequently cheaper. They are recognized by the US National Electric Code as valid test agencies. UL testing is still the gold standard because of name recognition, but they all test to the same UL standard.

So, there is nothing fishy. This is normal for cheaper brands.
Now, we can have a whole debate on if CSA testing is as strict or if these chinese companies are lying. Those are worthwhile discussions, but seeing a CSA vs ETL vs UL label just tells you which lab did the testing. They all mean it is tested to the standard on the label.

I think 25ft is max per code, that's why most are 25 footers. It has been a while since I took a look at that though so I may wrong, but I semi-recall that fact.
No you're right. I know extensions are deemed unsafe by most, but out of desperation I've been using one daily for 5 years with no issue whatsoever.

Quote from FuschiaHome408 View quoted comment :
"50A hardwire should be installed on a circuit breaker rated at 70A or greater"The issue is that the National Electrical Code (NEC) requires that a continuous load should not exceed 80% of the rating of electrical equipment. This means that a NEMA 14-50 receptacle with a 50A breaker and 8GA THHN is fine for a 50A intermittent load like a welder but is only is good for a continuous load of 40A. The NEC defines a continuous load as any electrical draw expected to run continuously for 3 hours or longer. Examples include EV chargers, pool pumps, and electric space heaters.
Yeah I have mine on a 40amp breaker with 8 gauge UF-B wire. This was ten years and of course my charging needs have changed, so regretting not using 6 gauge wire and a 50 amp breaker.

I have had one installed for 4 months and it is basic but works as advertised. App is pretty bare bones but it lets you schedule charging times and that's all I need.
