For US models, it's so easy to install a smart EV charger that it's commonly done as a homeowner DIY project. We installed ours one sunday morning. Super easy.
@@efixx Similar. While TN-C-S connects the ground conductor to the Neutral conductor after the supply panel, in the US, we bond the ground and Neutral bus bars within the breaker panel, and keep them separate from there on out, and kept separated all the way to the device. This eliminates the chance of potentially energizing a device cabinet, whether it be due to conductor insulation failure, or miswiring. For a 240vac receptacle used for a smart charger, we have two 120vac conductors, one neutral conductor, and one ground cable supplying the device.
Another fantastic video! Really well done and very informative throughout. Would you need to run two data cables if you did not want to rely on the wireless mobile signal. One data cable from EV charger to the transformer on the tales in the meter cupboard or DB and then another data connection from the EV charger to the router?
Thanks for the feedback, much appreciated. 😊 Were actually going to answer your question in the third video in this series. Make sure you're subscribed and notifications on so you don't miss it, should be dropping in about 10 days! 👍
@eFIXX As a US based electrician (New York) for 20+years I can tell you that I have seen many diy projects anything from extending branch circuits to lighting to PV arrays. Most done poorly and without regard to the regulations in this case that would be the NEC (National Electrical code) which is the minimum set of rules for electrical installations that apply to all 50 States. On top of this (NEC) there is the code which pertains to the location Of the installation/s . Having said that , there's nothing wrong about diy as long as it is done correctly, but I am pretty confident that no homeowner insurance will cover any diy project should anything go wrong.
Great video Joe as always. I am worried that I am getting to like the idea of EV chargers and the installation proses ,what have you done to me .oh no I think I need to get a life 😂 Great video as always 👍👍👍❤️
How much should an installer be charging for mounting on an outside wall literally the other side of the consumer unit (which has spare slots)? Just had a quote of nearly £1,600 (including vat) for supply and fit of a £450 ev box. Seems pretty steep for what they call 2 hours work or am I missing something? Any recommended fitters in South Manchester?
Wow! We in Poland have to set up the charger by a qualified person and additionally the government office must allow this charger to be used before it is used.
Thank you very much Joe, very intelligent video as usual! Can you please tell us how to test the earth ref: probe please? Your help is much appreciated! Cheers Lincoln
The indra unit and team out of all the ones i tested seems to be the BEST built with most on broad PCB design the CPU broad isn't a Pi and also is made for industrial applications like this... I do reckon we might see it disappear from the unit but have a look at my deepdive reviews and everyones circuits this is by far one the best designs from an engineering point of view.
Quick question your e net connection as shown in your video where the enet cables which are low voltage run together with high voltage cable is this not again regs? As far as I know low and high voltage cables should never run together even though the cable you show has the 2 together any taught on this , good video though very informative.
Not really, it's actually one of the safer earthing arrangements for an EV charge point, much of what was discussed in this video related to TN-C-S systems. All the usual requirements for a circuit will apply and choosing the correct RCD is crucial. 👍
Hi is there any reason why you can't have a smart charger installed if you have one of the old meters with the wheel on it rather than a digital one Thanks
I have just had a Wallbox installed on the outside wall of my external garage by a sub-contractor of the installation partner of a major electricity supply company. Should I have received any paperwork informing me that the DNO had been notified? Should I have received any paperwork documenting the test results, resistances, disconnect times etc, similar to what would be in an ECIR report?
You should receive these but it's not something the electrician puts in your hand as he leaves. The installation certificate (EIC) goes through an admin process and is reviewed the the company's Qualified Supervisior before it is released. It will likely be several weeks before you receive this.
Great info. Thanks. I don't actually think the unit looks good, but each to their own I guess. I much prefer the Tesla Gen 3... Even though it requires the PEN device as a separate
I must be dicing with death using my 7 year old PodPoint with a type AC RCD, no PEN fault protection, no DC fault protection, no local earth rod! It does amuse me that the IET have got so excited about all these theoretical fault conditions. You know what will kill you, your house being burnt down by some builder electrics or some crappy USB/multi-socket calamity you brought off Amazon. Excusing the rant, its good to see more progress towards more safety just wish that was true more widely.
Hi my installer has used t&e 2.5mm cable to install my ev charger can you tell me if this is suitable I'm not a electrician but it just seems to small a cable for the job Thanks
Great video I question what you stated that it's unlikely to be greater than 100amps. Each home is differant so adding curtailment can sort out some issues again depending on what your max demand is. If you are all electric and possibly have a large heat pump then you could be close to your limits in which case the load curtailment will be of use. BUT if you need your ev ready for a long journey and say you only charge in a set period due to a tariff, then having an ev charger with curtailment prob won't work for you. Again every home has a differant seniorio. Family homes have hot tubs running, and if family's like to save then everything tends to go on in the economy 7 period. So your ev won't be ready with a full charge. Again if your large home has a 22 kw heatpump then you would most certainly have to curtail the charger at a cost of ev not ready with a full charge bearing in mind a 62kw battery from say 28% to 100% could take 8 hours and new battery's are becoming bigger so double this using a 7.4 kw battery. And another issue will be not so much now but in say 5 to 10 years time second evs and chargers will be required for a working family using ev every day. If your a retired then you would proberly charge once a week so no issue. The heat pumps depending on size and say temperature will affect md specially in colder months. The standard 7.4 kw ev charger will be outdated and the basic will become 22kw for bigger ev battery's with respectable range. So the question is is single phase going to work for every family home possible not.
Gino a 22KW heat-pump has an input power of around 6KW. Your EV is definitely not going to charged if you blow the cut-out fuse - that's the point of curtailment. A 100A supply is capable of delivering 192KWh over an 8 hour period (£50 of electricity), you're doing something industrial or live in a mansion if that's not adequate. Looking into the future you're going to see much more intelligent load management where energy is consumed when it's more available, and this will be sure to look after your supply. For 99.9% of scenarios its perfectly reasonable to charge two EVs and heat a home off a 80-100A supply. As someone who has an EV I can't see a need for 22KW home charging, The battery just has to be full by the morning and its almost impossible to know a scenario where I would get home with an empty battery and must have a totally full one by first thing in the morning - if for some reason that did happen, then I'd just have to use a public charger slightly earlier in my journey - not the end of the world.
@@edc1569 great feed back thank you. What I was trying to say is with battery power increasing we see 107 kw battery's and new to the market 207kw which has an estimated range of just under 723 miles. So going back to the start when cars used the 13amp plug in where cars had 24kw battery's. Times have changed we went to 16 amp then 32 the humble 7.4kw chargers for our 40amp circuits. Now if I had the new BMW with the 500mile range with bigger battery my times on the 7.4 kw chargers will double. So this is why a 22kw charger will be needed at some point As for using public chargers which are getting better its a waiting time of 1h34minutes for me to charge my car ready for its return journey. My dno would not accept my second charger at full load so I have concent from my dno and been advised not to use full load on my single phase supply. I guess they were concerned with loads as you stated and That means under ideal conditions, a balanced load, it can serve a maximum of 240 volts x 100 amps = 24,000 watts, otherwise known as 24 killowatts (kw). You should never load circuits more than 80%, so you have 24 x . 8 = 19.2kw. We opted to use 2 ev chargers and have put on hold the heatpump. Just one charger on full load runs at 28amps for 7 hours. Battery between 20%30%.charger reduces as it gets near 100%
What makes zero sense is there's all these rules yet you can just plug the car in using the Uk 3 pin plug and lead and break all the rules and no one cares.... if its so dangerous why do car manufactures give you one of them leads??
Why did you edit regulation 722.531.3.101 and remove the word “individually”? It’s an important word as it means that the EVC circuit should have its own individual RCD, not sharing an RCD that is protecting other circuits.
I'm from China and EV are really popular in here. However the EV charger installation is always problematic because the contractors tend to use cheap *ordinary* MCB and RCBO for protecion. For domestic usage, those ordinary RCBO should work well because literally no one would consume 7kW of electricity for like 10-12 hours continously. For myself, the RCBO tripped twice because of over-heating of the bi-metalic strip (not by residual current protection. Otherwise there will be a differnet button pop-up). The charger is a 220v/32A single phase charger. The RCBO is C40 rated and the cable is a 6mm^2 copper cable. In theory, it should work like charm because it's only 80% rated capacity. But I'm not the only one suffering the similar problem. My friend using the similar setup burnt out his RCBO completly after prolonged use. Terrible, really.The cheap RCBO may not be suitable for EV chargers. They require something with more consistent quality control and robust design, maybe moving towards industrial grade components.

Its similar here but not quite as stringent, you need to notify the power networks of the installation under most circumstances.

Oh dear, another chargepoint with a whole bloody Linux computer inside. Complete overkill, waste of power and so many more ways it could go wrong.
Cheap and easy to replace? A lot cheaper than the circuit board in my gas boiler or other proprietary circuit boards?
It all allows for external control and safety settings.
@@bencampbell2041 But much more likely to need replacing
@@efixx So would something more appropriate like an ESP32 module.

If you want to charge at 7kW then it’s too small.
@eFIXX thanks for replying I just thought it did not look right and cable gets hot when charging
