[@blitzmeister3356]

Regarding your dead battery: the energy for the start-stop does not come directly from the battery, there are big capacitors under the left fender, who then dump the energy in the alternator (which is actually called a startergenerator) to turn over the engine. When the engine is running, the capacitors are directly charged by the alternator, so there is none to very little direct battery drain. I think your problems might have something to do with the accessories in your van, especially the hot water heater - you once said it draws about 20 amps. If this isn't correctly wired it could bypass the vehicle energy management system and therefore it doesn't register the additional power usage. Because the alternator does only charge the amount of energy which has been taken out (and has been measured), it simply could be that the battery isn’t held at a sufficient level and slowly dies.

For plugs in cabinets we cut a 60mm hole in the cabinet and put in a desk grommet and a double socket next to it and it looks very neat and you can fit a plug through without cutting off the plug

[@silviustro1]

Tom, you can shut down the Start-Stop system on Renault cars/vans, both manually using a button on the dash (RTFM). Or permanently by modifying the ECU configuration (at the dealership or at a repair shop). I've had this issue as well, needed to swap my battery as well. BOSCH batteries seem to last much longer if you continue using Start-Stop tho.

Pass the plugtop through, then place a single blank plate on that side. I'll send a tweet with a pic 🙂

stop/start is to get the "grams per kilometre" CO2 rating of the vehicle down to lower the rate of tax (ironically because it's "better for the environment", *apparently* ) - if you turn it off though you can still pay the same rate of tax, they just assume most people will leave it on so they go by that.

Totally with you on the van batteries. The stop start batteries are much more expensive too. And the alternators fail more often due to the heavier demand and they are 3 times the price. Stop/start barely saves any fuel anyway, it just lowers emissions in cities slightly.

[@Bin216]

That flat installation is TN-C in the mineral insulated section, then TN-C-S from the connection blocks. Apart from the meters and supplier fuse being in the middle of the TN-C part, it’s exactly what the DNOs do to install a TN-C-S supply but they just cover the joint in insulation. Wouldn’t want to say if the regulations permit it though…

Often seen an original TNS changed to TNCS, what was the main earthing conductor from sheath becomes a main equipotential bonding conductor . As for plug top we cut big hole and fit desk grommets that close off hole up to flex

[@TheChipmunk2008]

good call on the old sheath being an extraneous conductive part now... very good way of explaining it

[@effervescence5664]

Single core MI is so they can up the amp draw without shorting the cable and without taking up more space. It would have been TN-S as the conduit/ water would have been used for the main CPC. What has probably happen is the original has probably been linked due to issues with the sheath (broken cpc outside the block) so it would be classed as TNC-S at the supply origin as it's linked to stop induced voltage after a break found on the building supply cpc. So now they've converted the entire block into TNC-S, this sadly is quite common for cash strapped blocks of that age that suffer with broken supply cpc. It's not taught in colleges and like yourself many engineers look at it and are mind boggled. The BS 3871 / BS EN 60898 should be put in the report as a 60898, this is the number used after the merger with the EU back in 2004 - it's down to harmonization but essentially it's the same thing. Broken CPC is down to capacitance, I believe JW/ GSH and others have videos on it. The start of this video is exactly why we bypass the stop start on all our vans from the day we get them. Ever since stop start almost got one of the engineers killed on a roundabout the company is against it completely.

[@felixmoran1]

So the earth at the cu would have originally been fed by a water pipe? Making the whole system tns, but at some point the earth at the cu was swapped over the the micc neutral. It really confused me when he started saying it was tt as the earth was clearly coming from the neutral. Then at the main intake the earth cable coming from the armour of the supply cable is essentially earthing the cable from the installation tncs earth taken from the supply neutral. Would there have been a separate neutral conductor in the trunking feeding the micc cladding? Otherwise the trunking becomes a live conducter.

[@effervescence5664]

@@felixmoran1 Yes I don't know why he said TT or why they didn't correct themselves on the edit but it's TNC-S conversion not TT. You're correct on the main intake, the armour ring at some point back to the local transformer has been damaged and rather than dig up the road it has been converted to TNC-S. It was probably damaged long ago but no one would have noticed as the main water incomer at the main intake is bonded to it, but as is the water boards remit all old metallic pipework changes to plastic and then you lose your earthing conductor completely. Yes from when we have worked on them the MICC has been glanded at both ends and kept separate from things like metal trunking and wrapped in something a kin to denzo tape. Having note seen inside that trunking though I couldn't say for sure, though the badly done connection in the flat gives me a horrid feeling that which ever engineer did the conversion was not informed how to go about doing it safely. Though if everything in the building is connected to that trunking be it CPC or neutral the theory states the potential voltage difference is 0 volts and no shock risk. Not being there to test it I wouldn't like to say it's 100% safe in the current format though.

[@felixmoran1]

@@effervescence5664 thanks for the reply, why would the earth at the cu need to be swapped over for the conversion though? If it was a water pipe or conduit taking the earth to the flat originally, it wouldn't matter that the intake supply changed surely?

[@effervescence5664]

@@felixmoran1 I see some unused conduit below the CU in the flat, but normally the earthing arrangement up to the CU wouldn't have changed unless it had to. So you're right in that regard, supply characteristics changing at the intake shouldn't have effected the earthing arrangement to the flat. So possibly the earthing arrangement was an issue (missing after conduit disconnected or water pipe removal) hence they changed it to TNCS at the CU, or I am starting to think more is more likely they realised they had made the trunking live and have converted it all to reduce the potential to 0 volts.

[@AintBigAintClever]

With the loose earth scenario at 19:00 you've effectively got a potential divider. Several metres of T+E with high (but not infinite) insulation resistance and an earth wire slap bang in between the two potentials. Any sort of load would haul it one way or the other, but a high impedance meter shows the stray voltage that's present. 3-pin equipment with input filter capacitors would make more current available on the earth wire, you might get a tickle off it then. We had that at work where one of the sockets feeding a bunch of PCs had no earth. I discovered that when I got a buzz from one of the PCs whilst also touching a metal desk frame.

In my opinion the incomer is TNCS. You have a connection to the outer armour that is connected to the neutral of the 3-phase supply. That is TNC-S. As long as the Ze is

[@sstorholm]

Dishwashers usually have a recessed area at the bottom for plugs and water connections, so I just did a recessed socket really low down for it, like an inch of the floor. This is however outside the UK, so I’m not sure what your regs say about that, but it has to be better than a floating socket. If the back wall allows, you could even recess a box so far back that the plug is recessed with it, a bit of plaster board or some premade metal box and you’d have a really neat setup.

Stop start, the Battery Management System has a depleting counter so the battery only has a finite number of starts usually. Is there no way of turning of stop/start via an OBDII scanner. Also, sometimes you can use a sequence of button presses to reset the BMS when you fit a new battery.

[@jimmyb1451]

Totally unnecessary "feature" to have to reset the ECU on a battery change. I wonder if you can fool it by connecting the two batteries in parallel while changing them over. Either way, the correct answer is to just not buy one. Support manufacturers that aren't there purely to force you to go to the dealership and harvest as much data about you as possible with their "connected cars".

[@simonparkinson1053]

Devices are available that are basically a timer - about a minute after switching the ignition on they will pulse a relay or optocoupler once - the "contact" of which is connected across the auto stop start button to simulate a press of the button so you don't have to do that every journey.

[@simonparkinson1053]

@@jimmyb1451 No, the charging voltage and current profile is changed over the life of the battery. Fitting a new one with or without disconnection will result in overcharging of a new battery and cause it to fail sooner than expected. Having a leisure/auxiliary battery connected with an old school big clunking relay/contactor split charge is a sure fire way to end up with both batteries failing sooner than expected. They need to be charged using a specific DC-DC converter, sometimes known as a battery-to-battery charger. Modern vehicles disable charging under hard acceleration to give you more hp at the wheels, and increase the charge rate during deceleration (sort of regenerative braking) but all that is very hard on the battery. I say modern, but some Ford vehicles have had smart charging for 20 years.

[@jimmyb1451]

@@simonparkinson1053 Yeah, that's not how battery charging works at all. It's also not the reason the ECU needs to be reset. I haven't seen the systems, but I have heard of newer cars connecting through a shunt resistor to monitor current in and out of the batter (meaning a careless connection of a battery charger can put the vehicle into limp mode because the measured SOC doesn't match the computer's idea of where the battery should be in it's charge cycle, which is utterly ridiculous.) At any rate, if indeed a split battery system can in any way end in both batteries failing due to overcharge, that's far from what I would consider "smart charging". Either way, none of this is necessary, let alone required.

You are correct, though - it was often the DNO that did the conversion on these. Sparks aren't allowed to but I have witnessed certain blocks be converted like this when it's deemed required by them.

[@effervescence5664]

@@HAelec1 Sorry, badly written. To clarify I meant a C3 for being TNC-S as I don't know how they've kept the neutral separate from the earthed trunking at the main intake - ones we've worked on they're glanded through paxalin, solded onto the sheath for the neutral and then wrapped in something like denzo tape. The bare neutral inside the flat below the board C1 in that state every time, and if the trunking is the neutral C1 though argument could be made if the entire installation is TNC-S anyway potential voltage between parts is 0. Without testing that installation it's difficult to judge from just the video on that one. & yes I couldn't see and RCD protection in the main intake from any of the shots in the video or fused protection of any kind outside the main incomer head. It's definately one I'd be asking the DNO about because if it has been converted they should have a record of it.

If they also happen to upgrade the incoming Head at some point, then they’ll always call it a PME, (whatever the supply cable is doing,) make use of the PME MET, but leave the TN-S connection ( conductor or band) in place. It’s a pain if you’re trying to get a true Ze on a 1ph as you can’t always disconnect that parallel earth! So, if in any doubt, put TN-C-S. The flat end is a different kettle of fish 😂

[@MrEvolutionist]

in aus we just put a single outlet in the space next to the dishwasher/washing machine and drill a hole through and plug it in.

[@ARElectrics]

It looks PME with the earth block going into the neutral cutout as you record intake not the distribution circuit. But I'd test it to check as the outer sheath is connected to make sure pme is there and the value it should be. Not seen the single core MI before but have seen 2 core for distribution and the outer was the earth. Shouldn't be combined. Saw the 6 sockets are you sure they didn't want 3 doubles 😁 had it before someone asked for 6 sockets and I had to ask do you mean 6 sockets or 3 double sockets to be clear.

[@cjmillsnun]

I had 6 twin sockets together near the TV. Once you have AV amp, Blu Ray, Home theatre PC, TV, router, set top box and in my case because I have a huge physical music collection, CD Player, turntable and cassette player (yes I still play tapes and vinyl - I'm old!). I also have my phone and an extension running for a laptop power supply. That's 11 sockets used. I have 1 socket spare. I didn't have all 6 at one level, but 2 banks of 3.

[@ARElectrics]

@@cjmillsnun there are those very rare occasions yes. 😁 can never have enough of them

[@Sierraomega1991]

I have 4 doubles at my TV and still need two four way extensions

We're on a roll now Tom 👍

A crate of Bosch stuff ! Living the dream mate

[@HeathenGeek]

For other stuff to talk about. . . I'm still looking to find out more about pricing: what books are used if any? Actual books with actual 'you're going to put in some sockets, this is how you break down the costs' type of stuff

[@stephenwilshaw3052]

Ha Ha! Loved your what-the-helling off Sarah. Really liking the new format and the variety of jobs you show.

[@ediijay9897]

Please please make a video elaborating and explaining more the reasons why you get a voltage when you have no cpc. A voltage where and for what reason? Thanks.

[@iangreen6121]

Used to work at a high street electrical retailer, leave that to your imagination. You can cut the socket off, manufacturers can't refuse repair if that's not causing the fault.

[@aidanoconnor3757]

Regarding the washing machine socket. We here Ireland use 20amp double pole isolation switches above the counter top to break the mains to the socket below the counter. Some brands like mk, crabtree have pre labeled isolation switches with washing machine, tumble dryer ect. already on them. The tiler will hate you for it though. Extra work for them cutting around the additional switches. Part of the regs here for appliance so had to be done.

[@Ragnar8504]

Actually the flat looks like a TN-C-S to me. L+PEN in that single-core MICC and the installation's main earth comes off that PEN. So from the incomer to the flat it's TN-C and TN-C-S from there. The incomer would be TN-C-S with two parallel PEN conductors I'd say, once they'd connected the sheath to the neutral terminal. The one thing you can definitely rule out is TT because there's a link between neutral and earth. If it was a TT you'd just have a main earth from an earth electrode. Single-core is cheaper and possibly has a higher current-carrying capacity. Cost-cutting isn't really a new thing. The last kitchen I did specified all whitegoods sockets on the wall/flush at 100 mm from the floor, i.e. behind the kickboard. The best part of the job was when the kitchen plan specified a single cooker connection but they actually put in a gas hob and oven on a plug top, i.e. they needed a double socket. I had to fit a double socket underneath an already-installed cabinet, laying flat on the floor. Quite an uncomfortable position! I think the voltage between neutral and earth is either capacitive coupling from the parallel line conductor or via filter capacitors in something that's plugged into the circuit. The latter can give you a decent belt, which is why a CPC continuity check is the first thing I do if someone complains about getting shocked from the dishwasher.

[@wyndavies5044]

Get some of them desk things you find in offices. I just stick that in the floor of the kitchen cupboard to bring the plug through. Hides the hole nicely!

[@OscarSturgess]

Whenever I'm not sure on TNS or TN-C-S I tend to go for the latter, purely because the max Ze is lower, and so if it meets the requirements for that you're good regardless That's just what I would do however, I'm not sure if it's the correct thing to do

[@GARRYEASTON]

Make sure you note somewhere on the cert that its both!

[@frimleyfrodo]

I have had my VW from new and have always had the stop/start switched off. I’m now at 6 years old and 163k on the original battery. As I keep them until about 200k, there was no way I was subjecting the battery and starter to undue stress to save a possible couple of mpg.

[@Marcel_Germann]

They did actually something which is usually not permitted, at least not here in Germany. Incoming is TN-S, so separate neutral and CPC. In the basement they united the separate CPC and neutral to a PEN which is then split again in the flat. And usually it's not permitted to reconnect a once separated neutral and CPC to a PEN again within the installation. I don't know how this is in the UK, from a safety aspect this is ok if the PEN is at least 10mm² in copper or 16mm² in aluminium. But PEN conductors can cause electromagnetic interferences, that's the reason it's not desired to have them within the building. But here we got a lot of old installations with a PEN in final circuits, with wire bridges on sockets (PEN connected to CPC terminal and wire bridge from there to the neutral terminal). That practice was permitted until 1973.

[@Marcel_Germann]

It starts as TN-S, turns into TN-C and in the flat it turns into TN-C-S.

[@RichardArblaster]

Great video Tom, looking forward to the Highways content when you get the course done 😎

[@jonathanbuzzard1376]

You can get cutting dust extraction hoods for a grinder. Third party ones are not expensive, £25-30 though I recommend a clear plastic one so you can see what you are doing. Makita and Bosch do there own for a *lot* more money if your that way inclined.

[@Chris-hy6jy]

Disconnecting the earth on a circuit will allow the earth conductor to float and a voltage to be induced onto it, either through coupling in the cables or via noise filters in appliances.

[@simonparkinson1053]

Went to a property once, complaint of getting a tingle off things. There was 86V between the computer and adjacent radiator. Intake in utility room, submain from 30A 3036 in there via lead sheath "T&E" of approx 2.5mmsq to a Wylex 3036 board under the stairs. All circuits earthed at the board, except for the incoming submain. With all the other non-compliances and WTFs, it got a nice rewire.

[@nbmrbluesky3688]

Loving the longer videos

[@nicoduck]

I'd prefer to have the socket in the cupboard next to the appliance and put one of those desk cable grommets into the kitchen/hole there. Should look quite neat I guess.

Try cleaning contacts with a glasfiber cleaning pen - works really good for me

I would love to see an explanation to the difference in these systems. I think it would be useful if a video were done explaining the differences in the system. Plus being from Canada, I have no clue as to what these systems are but interested in learning anyways.

[@glenswhispers]

Likewise, we primarily have MEN system in use here in NZ.

[@alfielee6804]

Another excellent video good work Tom and the team 👍

[@oscar4321234]

Voltage on the earth will probably be just induced voltage because the earth is floating, its not a real voltage. If its showing an actual voltage between neutral and earth its probably a disconnected neutral. The TNC-S/TNS has probably lost its original earth at some time so has been converted to TNC-S, the lead sheathing still needs earthing/bonding though same as a gas pipe.

[@Jim_Newlands]

You have definitely upped the game on your channel content of late. 👍 Had a laugh at the "googling what a floor brush is" comment.

[@Calder1169]

Socket in cabinet, cut a 60 mm hole to pass the plug through, and a cable tidy to fill it.

[@lucatrifan2797]

It would be interesting to have a shore supply plug on the vans (similar to the ones on ambulances) to charge the batteries at night

[@JustinCase136]

Love the longer vids and more diverse content Tom, can't wait to see all the Highways work on here too 👏👏

[@craigbrown3019]

what the electrician has done in my kitchen is put socket underneath the counter on the wall with an isolation switch above the counter

[@Noname-dc9mm]

And let my guess no window above the appliance either.

[@danielbrydon3869]

The BS3871 and BSEN 60898 markings are quite common on MCB's manufactured around the time of the change. You may also come across some labelled as part of both standards, eg B type 3871 instead of type 2.
