You got me going there with your Earth leakage tester, I think I know why when you measured leakage on the pair of meter tails, it registered 11 odd mA leakage, and yet when you measured on that earth wire it measured zero mA, so what that means is the earth leakage current is not going through that yellow green conductor, but is getting earthed somewhere else , directly into ground either through pipe work etc, so that should stop you scratching your head. And of course, you need to enclose both live and neutral in the tester jaws, and any common mode load currents would cancel each other giving you any differential mode current read out, so even if you had a load of 5 amps you would be seeing 5.011A in the live conductor and returning exactly 5.000 amps, whereby 0.011A going into the ground through another earth point and not that yellow green earth conductor.

Videos like this are really helpful for trainee electricians :)

Great video, keep them coming. Like your way of presenting bad situations and remedial work you have to perform (if you can) to rectify the problems.

To resolve having 4 conductors in the MCB where you have doubled up the ring you could have connected one leg of ring 1 to one leg of ring 2 with wagos and then you've got one bigger ring 👍

Some points for future. When using earth leakage meter beware you may not be able to read a value if clamping around the CPC as there are possible other multiple pathways to earth - the gas and water bond, you would have to remove them to see it. Looking at the imbalance on LN was the best approach. On RCD tripping you have to remember the cooker/oven has probably a capacitor built into the electronics which with the long run you had could be causing the tripping. If it was a type AC I would replace with a type A. For EV charging when you have to TT my advice is to carry a soil test kit. This has several benefits in that you put the right type of earth rod in. With soil ph around 8 or more you can get corrosion of a pure copper rod reducing the protection over time in using the charger. Two ways around this either get a copper rod which is anodized with a noncorrosive metal on the surface or get a larger steel rod. I would also surround the copper rod. In concrete as well providing more reliable earthing and reducing the possibility the earth rod resistance would go up in summer. Anyway nice work as always.

If your 11mA of leakage isn’t returning via the consumer unit earth block, check the bonds and also clamp the water and gas pipes before and after the bonds, as it might be going out via services. You might have a screw somewhere through a live leaking it to the fabric of the building. Clamp the circuits and see if you can track it down.

@KX36

any modern device will have some earth leakage. Switching power supplies in modern devices have a class Y capacitor across the transformer to suppress EMI. The secondary side is earthed (class I) or double insulated (class II). The primary is live and neutral rectified. capacitor from live/neutral to earth creates earth leakage. Personally I don't like USB sockets because they're like having the cheapest £5 charger permanently plugged in. They won't have modern fast charging features, so they'll be obsolete almost immediately, they probably don't have great isolation from primary to secondary, and they're probably very noisy and wasteful with their standby power.

Very interesting Jordan, thank you. In this case it look like the customer misled you, to some degree, as to their rediness for you to do the installation - of course this may not have been deliberate, thay may have been misled by others. How you fo deal with this situation, for example do you try to negotiate an additional fee for you time in sorting the issues, or do you stand by you original quote and just accept that "some you win, some you lose". I'm thinking that, over time, if wins and losses cancel out maybe you've concluded that you have your estimating strategy about right?

I've been using these soft tails for a while now. They are so much easier to work with. It's best to untwist them a bit before going into the main switch. Does anybody else not have much faith in those small allen key terminals used for the 100a dp switch. I have tried to get a torque version. I use a Boddingtons T bar at the moment.

Aside from the rising inflection at the end of every sentence - a good video!

Enjoying your videos, thanks for sharing! Is it the DNO that should be responsible for installing a dual pole isolator switch. I have a similar arrangement to how you described this property originally where there was no isolator switch just the DNO fuse to a Henley block used to feed two different (main and extension) consumer units. The Henley block case is cracked so I know it will need isolating to replace at very least and thought an isolator switch sounds like a good idea anyway. Contacted my DNO and they say they’re only responsible for the fuse and I need to contact my supplier (who I pay my bills to) for an isolator switch quote, does that sound correct?

Jordan can you tell what cable cutter device you used in the consumer unit when you were fitting the tails. I fit smart meters & i am always looking for something better than cable cutters. Thanks

Yep, lower left 4 looks a little loose..... Awesome tip on that mirror. Lovely job Jordan. You have probably mentioned this before but where did you get the cable stripper? Is there a link to it on your tools page?

Those red and black tails rising into the consumer unit might turn out to be compliant. I've seen similar ones where there are two layers of PVC, with the sheath using the same colour as the insulation. It can be tricky to be sure without stripping a small section and seeing if it comes off in separate layers. I wonder if the cable can be confirmed as sheathed if it has the usual markings on it like BS6004 6181Y?

I really like your videos but the motion sickness is real!

I would have joined the lighting circuits on this one to free up a spare way with it being a single rcd board. Does the ev charger have a type s rcd as I was wondering about the high earth leakage already

Earth leakage clamp is always best to put round the tails for an accurate reading as the main earth will probably have abit of diverted neutral current going through it . That’s why it was overloading on the mil amp range.

Is that (unmeasured, but apparently more 20mA) earth current inductively coupled then? It would seem to be much larger than the live-to-neutral imbalance.

The DNO fuse was still in right? But you had the main tails isolated via that low level isolation switch?. But there was no lock off on the switch as far as i could see. Ive had main switches that switch almost with the touch of a feather. I was getting twitchy bum hole syndrome when i saw you working on the tails 💩 I also love the mirror for breaker/bus bar inspection. Absolutely great tip Jordan.

I watch quite a few channels like this, and there seems a trend where when poor workmanship is found that doesn't meet code those who discover it don't want to name and shame or report them to the authorities that govern the installation standards. Maybe if there was some form of reporting, and some for of registration like in the gas industry there would be less cowboys around and installations would be a lot safer as anyone cutting corners would be "struck off" or have to pass some form of exam

unfortunately work like that seems to becomng the norm, and until someone gets a grip on the industry it wont change

You may not have measured anything on the earth cable as that might not be the route the leakage was taking. A conductor leaking due to damp may not show anything on the main earth cable.

Metering cupboards are just that...for metering equipment, cut out, meter and DPI when fitted. Now getting more and more crammed with PV isolator and associated wiring but never (yet) found a CU in one! Surprised how the DNO fitted a 100A fuse in an 80A at best cut out.

Another issue having this armoured cable wired directly from the mains means there is no discrimination from the other circuits. In other words, you can't isolate it, even if the mains switch is open/off. I really don't like installing load centres (consumers units) under kitchen bench tops, as main switches are meant to be readily available. (Australian prospective)

Why didnt you connect one of the lives from the downstairs ring with one of the upstairs, same for neutral and earth then you would have one big house ring. solves the problem of having 4 cables in a breaker.

It will only be a problem if people continue to upgrade to 100A "just because". A charger that's limited to e.g. 10A still can charge 12km/h or 120km overnight (10h). For most people who can park in their driveway every night that's more than enough. (Meaning they can charge to the full range of their car on normal days and only run into issues if they need the full range on two consecutive days.) Yes, a nice 32A charger will give you 380+ km/night each and every night, but how many people (aside from taxis and other business vehicles) actually need that? Many people seem to think they need to be able to charge their 600+km battery from completely empty to full in half a night at home. And if they drive 150,000km a year (600km*5days*52weeks) that's even true. But otherwise it's just not needed.

am I wrong or is the supply providers isolator two seperate switches as apposed to one double pole isolator ?
