🤣 Thanks Matt 👍

Thinking about this and long term into the future i recon that off peak will soon become peak time.... as there will be more of us using chargers during the nite time thus creating a higher demand..... cheap rates will be a thing of the past...

You're welcome Phil 👍

Glad it helped Nigel. Cheers 👍

Thanks

Thanks 👍

Pop Point has PEN protection and 6mA RDC-DD built in. It needs an external 30mA Type A RCD with 32A Overcurrent protection

Hi Osman. Thanks. I get mine from Yesss. You can't buy Pod Points directly or from CEF.

Hi KOKO. I think you might be confusing the terms "B Curve" with "Type B". The curve relates to the overcurrent protection of the RCBO and the type relates to the current waveform and its capabilities of detecting DC current faults. They are 2 entirely different things. The installation and charge point parameters will determine whether you need a Type A, B or possibly even F RCD/RCBO. The MCB or "O" part of the RCBO will normally be a B curve. I have never come across a Type B RCBO, but you can get a Type B RCD. I would suggest getting a qualified electrician experienced in EV to check your requirements

Proteus do a plastic 4 mod IP68 bare unit. I've used this solution once and fitted it next to the external meter cabinet. I carry several of the Proteus EV mini DBs in the van and just swapped the innards on this occasion so that I'm not mixing manufacturers. Works out cheaper than buying the parts separately

Generally speaking, either the consumer unit (fuse box) or incoming supply tails (from meter) are acceptable to supply an EV charger

PEN protection usurps the need for an earth rod and all chargers sold for the UK market incorporate PEN protection. Tesla Wall Connector is the only major charger I know without it. An earth rod is only required if you haven’t got PEN protection. In that very unusual case, you would basically make the supply to the charger TT, so that loss of the N conductor still leaves an earth path. You then have to be very careful with bonding in the 10m equipotential zone to avoid introducing a potential difference under fault conditions. Also, in urban areas, fitting an earth rod is not a clever idea as you could easily hit gas, comms, power or anything else, even if you could actually drive one in. Even if you did, everyone around is probably on TN-C-S, so unless the property is detached and a long way from any neighbours, you're opening up another can of worms regarding equipotential zones. There is no requirement in the Regs to fit an earth rod, and given the above, why would you even bother? It's cheaper and safer to fit the included PEN protection or buy/install a Matt-E or Garo PEN fault device in the exceptional case that the charger hasn't got it.

It depends on the installation method used and the type of cable. If the RCD device is upstream then it's not an issue, but if it's downstream then the cable may or may not need RCD protection. Without getting into specifics, if there's no RCD upstream then armoured is possibly required, but if it's all clipped direct then an MCB upstream should suffice because the "socket" outlet of the charger is protected by the internal RCD. It's all in BS7671 if you're in any doubt, but where people get confused is if the protection applies to the cable or the socket outlet. They're 2 different things

You're welcome mate 👍

Check that it's not a different appliance or circuit that's pulling the load and if the CT clamp is still giving inaccurate feedback replace it. Also check everything is installed and setup correctly. You need to get someone to test the readings with a clamp meter and fault find accordingly.

Under certain conditions, often when you've got a 100A cut-out and a low existing maximum demand, it's acceptable to do the notification after the installation

My DNO did not know what main fuse was fitted at my property mine is in a metal box with no label on the outside but I did a couple years ago have a smart meter fitted. They also upgraded the tails. Does this make any? Difference thank

You still need to know the main fuse size irrespective. Ask the DNO to come and check it. You also need to check if you're on a looped supply

@@abcelectric thank you I know I’m not on the loop supply I only got one main Wire coming in but you would think they know my fuse when I asked my energy supplier, the same question, they said they don’t give me that information they for am asking them something dodgy

@JAKE ROAD TO NOWHERE The best thing to do is to get a local EV installer to do a physical site survey and quote. They can then submit an Application To Connect form for an EV charger and the DNO will have to check your supply and fuse. Just because you have only one supply cable in your house doesn't mean you're not looped either. You could be last in the chain. Submitting that DNO form makes it all get checked

Hi. Thanks for the comments. I have no idea about unlooping an overhead supply. However, an EV installer would submit an LCT application form to the DNO if you're going to have an EVCP fitted. I can't see that the DNO's responsibility would be any different, so if you needed unlooping, they'd have to do it regardless. It's part of the ENA regulations. As regards making a video on it, there's no call for it. It's not an electrician's job to unloop a supply and we can't do it. The supply to a property is solely the responsibility of the DNO in that area. The fact that I discuss unlooping doesn’t change. In my area they're all underground supplies as it's very urban, but the same principles would still apply to overhead lines.

@@abcelectric Hi, thanks for the reply. I was just wondering if it was a less messy job unloosing an overhead supply than one that was underground? Not sure if the neighbours would be over happy! Anyway, I called my DNO after looking at videos and the lady I was talking to said she would get the people that deal with ev chargers and unloosing to call me and they did. They told me a fuse upgrade would be sufficient and they have thousands of homes like this.. I don’t cook on electric and I don’t have an electric shower or anything else that pulls lots of power so I’m hope it’ll be ok. I guess I’ll just have to get someone to come out and see! Thanks again for the reply. Much appreciated.

Sounds like you should be OK then. Regarding "unlooping", I would think modifying an overhead supply would be far less invasive for any neighbours than digging up their drives/gardens. Either way, they can't say no, and the DNOs do an excellent job at reinstatement.

@@abcelectric Hi. Yes I thought it would be easier with it being overhead. As for the neighbours not being able to say no, well I didn’t know that! Not that I would want to be at loggerheads with my neighbours! Thanks again for the reply and your help. Keep up the good work with your videos, always people out there looking for help. Kind regards.

Each DNO is different Keith. Some do and some don't allow other equipment to be fitted in the meter cabinet, although they don't own the cabinet as it's on your property. My understanding is that the top right of the meter cabinet is reserved for clients' own equipment, but I think it's a very grey area and you will get a different answer depending who you ask and who the DNO is. I can't give any definitive answer

Tricky one! If you mount the charger on your property and then use a cable cover to prevent a tripping hazard then you might get away with it. If anyone fell over the cable/obstruction you'd no doubt be liable and possibly wind up with litigation. Or, you could ask the council for permission to cross the footpath with a cable or to fit a charger on it and probably wait a few years for a "No". Private EV chargers without off-road parking are not a good match. If you installed one on the footpath without permission you'd probably end up in another legal battle. Just my thoughts from experience. Likely a no win situation, but whatever you do I'm not responsible for giving you my opinion 😉

It's Regs. Remember that a car charger could be on full load for 12 hours. That's a far cry from a cooker taking into account diversity, or a shower for 10 mins. The time/current characteristics of the main cut-out won't cause it to trip with a few seconds ir minutes of overcurrent. It's a different story over 8 or more hours

I have a looped supply with one other house. 16mm tails but a upgraded intake of 100A done by the service provider this week. He said it would be around £3.5k to £4.5k to have my own feed. Any idea if this true?

In my area the DNO upgrades looped supplies free of charge for EV charger installations. It can take a few months, but they do it. Needs all the correct paperwork submitting by the installer and you have to wait to fit the charger until then. That said, I find it extremely surprising that your service provider has upgraded you to a 100A fuse on a looped supply and also left 16mm tails. That's just asking for problems

Which equates to a fraction of the safety with a huge dose of stupidity, but you've obviously not watched through or understood. Long lead times are where the infrastructure needs upgrading, and no DIYer is ever going to dig up the road and fit a new 35 SNE/CNE cable with live jointing. As for charge point lead times , they're pretty much off the shelf, and the lead time to fit is so that the installer can do the pre-installation survey, quotation, notification paperwork where necessary, and book the job into their busy schedule. It'll then be fitted to BS7671 and won't cause a fire or kill anyone. You point me to a DIYer who would quite easily be able to do all that in an evening at half the price. 🙄 🤔

@@abcelectric Absolutely agree with that. The comment was mainly to appreciate your work and make your video more visible to others, there was no attempt to encourage doing stupid DIY things without appropriate knowledge. Thank you for your generous reply.

A bit of reverse psychology eh? Thanks for that then Volodymyr. That's given me a little chuckle 😀

That's going to be a much bigger issue in the future Gino. You could probably add a 2nd charger by utilising load sharing though

@@abcelectric yes I could but when one car is used, and we have had a power cut for 3 days now the ev cannot be used, so I was going to get a ev van but I cannot as we would both need charging every night. So looks like it's best to kerp a diesel. For us no diesel no work.

Instead of paying the DNO £15k why not invest in solar and battery storage

@@catherineshuttleworth5686 I have solar I have battery's. Its to do with how much load you use, using a 100amp cut out. If all my loads in my home were used together it would exceed the 100amp now. So this is why a I require 3 phase.

I don't write the Regs. My responsibility is to work to them and the point of this video was to try to explain them. When you actually realise that the Regs are essentially written to prevent 2 things - fire and death under fault conditions - then they make a lot more sense. As technology advances the Regs get more complicated. It's evolution and progress. What's annoying is people thinking that they're there to make money, which couldn't be further from the truth. They're there to save money and to save lives. There's zero analogy to TV transmission protocols.
