This video shows my day as an Electrician Installing an Electric Vehicle Charging Point for a Nissan Leaf. The Roles Charging Point was installed with an Earth Electrode as it was being fitted to a TNS system. The RCD built into the charging point protects it from both AC and DC leakage currents. It is also double pole as required by regs.

I don't know about that. The clips should be equally strong in tension or compression. Putting the ears down gives a nicer looking (at least initially) install, putting them up means that gravity will pull the cable against the wall instead of away from it.

A good presentation. What caught my eye was the existing meter arrangement. Many years ago, my house had a similar electromechanical rate change/restricted supply switch setup with an old fashioned meter like that. After that it was replaced by a radio-teleswitch (ultra long-wave) system and a digital meter, then later on it was changed to a fixed timing digital one so as to tolerate reverse current (when I had solar PV added). The existing kit would not be compatible with local generation (typically solar PV like my place), but also not suitable for those utility supply firms that offer EV cars as storage battery export. In general, those old meters will run backwards if they try that.

Thanks for your excellent explanation of your setup and particularly the earthing rod connections to avoid contact to the PME. I am still a learner and was trying to get my head round this kind of EV charging installation and your video has helped a lot. If a house is on a TNCS would you do a similar setup with an earthing rod if you were installing electricity to an outside metal shed in a garden that houses for example water pump and UV light filter, sockets, lighting etc? The metal shed is obviously an extraneous conductive part so it would have to be bonded to the earth rod. Would the shed MET and CU still have to be kept separated from the main house PME earthing system? Thanks again Chris.

Hello! Great video and a very neat job! Seeking some advice if you don’t mind? I’m considering buying an electric car in the next year or so but don’t know quite how I’d get the charger installed at home. I’m by no means an electrician so please bear with if I use half the wrong terms 😂 Does the cable leading to the charger need to come directly from the consumer unit or can it be run from other cabling via a spur/connection unit? Sadly my off road parking is at the back of my garden which is quite a way from the consumer unit; and as far as I know I wouldn’t be able to trail the charging cable across any public path to the car for obvious reasons! I already have outdoor sockets fitted with 2.5~mm 3 core armoured cable running close to the drive, however these are run off of an existing indoor circuit via a switched fused connection unit. To me, this would be the easiest option as the ideal location for the charger is close to this armoured cable, on the other side of a garden wall; but would this be viable?

@Tore_Lund 2 жыл бұрын

Late to the game, but I just found out: It is incredible that an EV needs a separate earth and that the EVSE between the socket and the car the needs a relay on that second earth?? How unlikely is it that an onboard charger fails in a way that puts EV battery DC voltage on the ground wire or the chassis, as well as the car computer, which always monitors isolation resistance between chassis and battery, not noticing? I know about SMPS and quality ones go to great length making sure this is not a way they can possible fail unless you throw a bucket of water on them. People have been charging different kinds of electric vehicles straight from the socket, even without an earth in the rain for a century as well as using ungrounded corded steel lawnmowers in claggy grass barefooted, and I've never heard of any EV owner finding dead mammals around their car in the morning for the past 40 years? I would like to know the reasoning in the legislation for treating EVs differently from any other outdoor appliance? Even tumbler dryers, which occasionally are wrongly installed without a ground and then have a short to the chassis, which indeed shock the residents when they find out, almost never off them amidst plenty of grounded piping typical of an utility room.

Do you think it would be acceptable to connect your SWA sheath to the earth rod and isolate the other end from theTN system earth? I was asked to connect a Tesla car charging unit which did not come with the required type B RCD so had to source a separate one which cost the client an extra £400.

Nice job. But I’m not keen on the clamp connection to the electrode. You’d get a maintenance free connection by sweating the cable on. That is what the supply authorities do when installing an electrode when putting a replacement pme service which connects to an old pilc distributing main. They usually just leave the electrode lying in the trench, so it is buried fairly deeply. You were lucky to get a nice low reading from the electrode.

At 16.39 - you say "needed to get the customer to upgrade the main fuse " ?? Surely - the capacity of the existing installation should have been checked before commencing works ? - Or in other words - part of the opening commentary - where external influences and design criteria have been considered - and the supply upgraded ( which it appears it needs to be ) before installation commenced - ie once contractually committed ? I'm assuming that this circuit will be a 32A circuit - which of course has no reduction in terms of diversity - so is a full 32A additional load on the system ?

Andy chara yeah I left the earth core taped up inside the box, so it’s accessible for testing but nobody can inadvertently touch it. I didn’t want to use an SWA gland as the brass gland would be an exposed conductive part connected to the TNS earthing system. No need to use proper armoured gland on both ends anyway as long as it’s earthed at one end it’s fine. Compression gland did the trick nicely. Taped up the armouring so it’s not exposed.

That's always been the case with any TT system tho. Do u know any sparks that attempt to access plans or CAT scan the ground cos I don't. U make an educated guess based on location of manhole cover, water and gas locations in the property. Not a perfect science but better than nothing. Also, why would u pre drill any material before putting a fixing in or driving a rod? It makes it easier because the rod follows the path of the pre drilled hole. Like Jordan said, it lets you find the sweet spot rather than attempt to bray a rod in 20 times.

@18in80 5 жыл бұрын

Where in the regs does it state you have to fit an earth spike in case the TNS supply is converted to TNC-S? If in the unlikely event it was to happen the installation would need to be reassesed and an earth rod fitted at that stage; similar to when water companies informed home owners of metal water mains being changed to plastic so they can get any their main earth connections changed to an earth spike. The electricity DNO would have to inform customers of a change to their earthing from TNS to TNC-S so as to allow customers to get their main bonding conductors installed/replaced, as many older installations will have none or have undersized conductors that are less than the 10mm sq. required for TNC-S.

@pauldelahay76 4 жыл бұрын

Plus if the earthing is lost. It means by default we would lose our Neutral would we not? This would result in instant release of the charge coil on the contactor.

Agree Paul Green, but thesedays you tend to get shot down by commenting on the proper safe working methods. Personally my thought is if its getting put out on a public forum, everthing must be done as per rules and regs. Why the 3 core SWA when only needing 2 core? Dont say the CPC is there to protect the cable, because thats never been the job of a CPC. Why the bodge of the SWA gland at the charge point - the reason given in the video is utter tosh! Is part of thart earthing conductor directly buried? Cos if it is 10mm don't comply does it? What was the reason for live testing on exposed end of the conductors? Isn't this what the dead testing is designed for? PS i'm not perfect in any way, but if you're doing this stuff for the world to see, get it bang on right!
