Well explained David. It seems so simple now you have found the fault, but definitely a head scratcher at the time. Fault finding is tricky and most guys I talk to, struggle with it, myself included some times. Experience gathered on site by others and passed on is like gold. Many thanks
After seeing your video, I initiated the same neutral/earth fault and tested the socket with my Socket & See tester and my Fluke mft. Neither of them picked up the fault. When I tested it with my Kewtech Loop Tester, however, that immediately tripped the rcd. So there we have it, very useful to know not to rely on the Socket & See tester in future.
You know it's good when non-sparks spend their evenings watching this. I'm just sorry you had to solve another problem caused by Nige's negligence, he'll clearly never learn 🤦♂️
Clever and well intended video. A lot of us would shrug it off as a faulty appliance! Great ending with the shout outs. The Brick scene was hilarious.😂😂😂
John Ward made a video about this same situation regarding the socket testers not showing certain wiring faults. So I knew that the socket was wired wrong but couldn't remember why till you explained it again.
You should be grateful that Nigel picked up the fake brick and not a real one , at least i'm hoping he did . Another excellent , funny and informative video.
that bit at the end with the brick made me wince. you had me fooled i had to rewatch a couple of times to convice myself it wasnt real. great video as always . i have also with good intensions made something theoretically better but just made it worse then when i started. thats the best way to learn fault finding thrown straight in at the deep end.
I always love your videos, but I can't unsee you doing chores!. As they say on crimewatch, don't have nightmares, sleep well.... I think there will be a nightmare tonight :(
Before I was a spark, I worked for currys and was looking at why an American fridge was tripping the RCD each time the door closes. After 2 hours of finding nothing on the appliance, and eventually writing the fridge off, before I left the customer, I failed to notice a row of copper pipes behind the fridge running up the wall. One of the pipes was prouder than the rest. That pipe had voltage potential on it, and the fridge chassis was kissing the pipe each time the door got closed, completing the circuit and tripping the RCD. Found by fluke - not the tester lol. Despite me proving the issue to the customer using a piece of wire to earth the pipe and causing the trip. The customer still stubbornly believed it was to do with the fridge - despite being unplugged at this point. I didn't bother to argue and just got out of there. At least by default, they got a new fridge out of it 😅.
@@dsesuk Don't get me started on earth fault riddled freezer defrost elements that cause intermittent tripping, that is almost never detectable at the plug top, But rears it ugly head on the supply every 12 hours or so 🤬.
@@dsesukI make absolutely sure that the appliance is faulty before advising a customer to get a replacement. A friend of mine told a customer that her range cooker was faulty, she got an engineer out to look at it and he couldn’t see anything wrong with it. It turned out the fault was with the cable connecting the cooker to the cooker connection outlet. My mate had disconnected the cable at the cooker connection outlet and IR tested upstream, as the fixed wiring tested out ok, he put it down to a faulty cooker and advised her to change it 🤦🤦🤦
The 16th edition only required RCD protection for "sockets reasonablly expected to supply equipment outside the equipotential zone". The requirement for all sockets to be RCD protected didn't come in until the 17th.
Hi. This is why your the master electrician….. now you can understand why that circuit was not on a rcd ……. The last wiring alteration developed the problem and rcd was removed It takes an old spark to find these types of faults and a master of his trade And as usual a good fact based video 👍👍👍
You can get socket testers that will test for reverse n-e at the origin of the supply (useful for TNC-S supplies). We use a Bicotest TruPol tester, and I believe that Martindale have bought out a tester for this purpose, these should detect n-e reversal at a socket outlet as well.
I'm not so sure Chris. Looking at the manual for the TruPol, it'll report a "N-E miswire" (i.e., missing earth), but there's no N-E reversal condition listed. With both connected together at the head and at the same potential, I don't see how any socket tester could report such a fault. www.bicotest.co.uk/datasheet/trupol_user_manual.pdf
@@dsesuk Correkt. You can ONLY find that error if you apply a LOAD higher than 30mA. Socket testers don't draw that much current. Your MFT can do that. If you measure Loop Impedanz ZL-PE *and* ZL-N, you always will find that fault. I like my Gossen Metrawatt MFT for this. If you measure ZL-PE, it automatically also applies a few Amps load to L-N. The RCD trips and the Gossen shows you an error message "N / PE Reversed!".
I fixed the same, but different. Followed a kitchen refit. Washing machine not working, unless the kettle was switched on... Go...... Mix up in the neutrals of the ring/spur legs
Here in Canada, the ground wire is bare or insulated with green. That's pretty difficult to mix up with neutral in white. Even so, I have seen light and ceiling fan wired with the ground as neutral and the white used as the second conductor, where a new wire should have been pulled in. I'm pretty sure that jenky arrangement is not up to code.
The fault proves 3 things; Murphy's Law, the fact you are actually human and not some electrical god, and that kitchen fitters are right up there with plumbers and innocent death row inmates; that is to say that they really shouldn't fucking about with electricity 😂
Hager pricing also doesn't reflect reality for three phase equipment. In countries where the domestic supply is 3 phase their three phase RCD's are about 50 pounds. In the UK the same three phase Hager RCD is about 250 pounds because 3 phase in the UK is only for commercial premises, not because of the actual cost of the RCD.
The FCU was directly above the socket position, so you wouldn't know the connection plate was there, but it turns out the cable from the FCU darts off out of zone behind the oven, then returns to serve the socket. I presume the original intention was for a socket to sit behind the oven, then they changed their mind and fed it from that point to the cupboard.
@@dsesuk the work of an evil genius, hellbent on causing future sparkies confusion and despair, foiled by the mighty wit and intelligence of....Nigel. (oh, ok, and yourself)
Lots of commercial properties use the MEM boards and as you can imagine contractors are constantly changing circuits about so that will probably be what is driving up the price of those RCBO conversion kits. Ask a school/university with a 3 phase board if they want to pay £100 for a RCBO kit or replace the whole board .. you can imagine they choose the RCBO every day of the week.
IIRC the rights to the memshield 2 range were sold off to "kempston controls". They put out a press release with a bunch of BS in it, but the reality seems to me they are only interested in milking legacy customers, not in taking the range forward. Even on a domestic, if you are only working on one circuit and need RCD protection so that your additions are compliant then paying a hundred bucks for a RCBO pod is still going to be much cheaper than opening the can of worms that is replacing the whole board. On commercial I suspect you could easilly buy ten or more of the overpriced RCBO pods and still be much cheaper than the can of worms that is replacing a DB.
@@bramcoteelectrical1088 The pods sold today by Kempston controls are type A, as are at least some of the pre-takeover ones but I'm not sure if they were always type A or if they changed specs at some point.
Never seen one of those circuits.... But yeah turn of the century estates are a fecking nightmare.... Me to sat nav: get me to the main through route, ASAP
I hadn't appreciated the 1630 was that old until I recently found some documentation online from 2002. There's a video from earlier in the year where I show it off. I like it, but it has a few annoyances that would drive me mad if used in anger - the dead/live lead swapping, the display clearing to zero a few seconds after any test and the lack of a memory for remembering the lead nulling value being the top three turn-offs.
Còuldnt agree more with the town planners & spaghetti layouts, i recently ended up in 1 of these noddy town new estates and spent more time getting out of it than i did visiting the customer, sat nav didnt help either as it was a new estate. I did notice though that nearly every dwelling had "Ring" doorbell & plastic picket fencing.
The downside we had with those pods was a high failure rate of the test button. They would RCD test correctly with a MFT, the button just wouldn't work. I suspect dust or oxidisation on the button contacts. As a rule you only got reliable RCD tests if there was some circuit impedance present. You got odd readings testing them at the consumer unit, but testing at a socket the results were OK.
I've not experienced any button failures, but you raise a good point there. The way these things work is that when you feed the line wiring down through the pod to get to the MCB's cage clamp, that wiring passes through a toroid. The pod monitors the magnetic field on line compared with neutral and trips if the field imbalances. You can't test it at the CU because your line probe is touching the MCB terminal which is before where the pod is monitoring for imbalance. There's no connection point at all on the pod to access line on its output side, so you'd have to test it in-circuit somewhere.

Sorry for the multiple comments David, but we state 'if we can remedy any C1/C2 faults on the day, we will do so up to 100 pounds value' (landlords are ok with this). Some sparkies think this is a conflict of interest... but it isn't if you have an ounce of integrity (i think you have a few)

Just picture a nice little get together with neighbours (or swingers) in the hot tub - all getting zapped (no RCBO) and then the heating staying on for a couple of weeks while they all decompose into a sort of slow-cooked stew!!

That estate is a carbon copy of a place called crompton acres in nottingham , same design , same shops same mem boards , are the walls straw by any chance
Fortunately not, although there is an estate in nearby Bearley that is straw walls. Actually Warwick Gates isn't too bad to work on - it's all block walls and dot & dab, so easy to cut in new accessories normally.
I really enjoy these videos, awkward faults with an explanation as to the why's. I'm glad someone else has as much passion for hating new builds as me. Goddamn greedy developers and corrupt and/or moronic local governments seem to be the norm now. Fuck other peopls quality of life, just cram them in, profit and quotas are all that matter. Never mind the actual humans who will live in them. Also I'm not sure your editor is quite upto the job, I'm sure I saw a helmet in the mirror.
On a job yesterday and the supply to their garage was a swa cable that consisted of a 6mm brown 6 x1mm blue with 6mm earth. So neutral is connected via 6, 1mm cables. I have never seen this cable before. Anyone here know if this is safe. The load should be shared but it's bizzare. I don't want to have to change the cable it's it's safe and sits correct with the regs but I can't find where it's stated otherwise. Cheers to anyone that replies
It sounds like a concentric cable. I've only seen it once myself as a supply to a flat, but it is used in distribution to provide supplies to buildings as in this case.
That sounds like "split con". There is a single phase conductor in the middle and then this is surrounded by neutral and earth conductors, with the earths being bare and the neutrals being insulated. The idea being that someone who digs through the cable will hit a neutral or earth first. There is no seperate armour unlike SWA. It's used by the DNOs for TN-S supplies. Strictly speaking I don't think it's compliant with BS7671 for underground work on the customers side because BS7671 (unlike the DNOs) considers neutral to be a live conductor.
No update from my point of view as I've heard nothing else from her, however I did hear from a local plumbing firm who'd also been on the receiving end of her wrath and from one of her neighbours who is taking her to court after being physically assaulted. I've also heard that this wasn't her house; it was her late mother's property. Karen lives in Coventry and this property has been empty for some time. The lass has problems!
Yeah, I'm talking minor stuff - repairs or rejigs that take minutes like changing out an incorrectly rated breaker or replacing a broken accessory. Anything that takes real time would be noted on the report and quoted for separatly. Usually a phone call to the person ordering the report gets a quick clearance to proceed.
Fixed ring has to be the dumbest thing ever (speaking as someone not really from that era) given that you would be omitting rcd protection to things that really need it ie appliances that deal with water and likely made of metal.
RCD/RCBO off, or neutral disconnected at the swb, and a test lead to verify the earth polarity and continuity is the only way to test for this and is the first test you should do. I come across this fault often when adding RCDss to existing circuits and all because people don't test properly. Interconnected neutrals on separate lighting circuits where a two way is involved is a good cause of random RCD tripping that is hard to find.
Great video. E-N faults drive you mad sometimes. I feel the same about kitchen fitters, particularly when they start telling you how you’re going to route the cables and site FCUs. Fuck off
I still use the little socket testers all the time. Just need to trip all PowerPoint's on the circuit. If it trips then it's wired correctly. Aussie earthing system though
I don't mind 'em chagring what they want, but I haven't got time for all the sparks who get dewy-eyed over Hager and insist that's all they fit. It's nothing special. In fact, it's sometimes downright rubbish.
but you found it any other spark would have put the rcbo back to the hot tub and said F it and put it in the observations took the money and run straight to that kebab shop, great vid,
Ah, good ol' Plan B! It might have come to that, but we knew it had to be a N-E swap somwehere. The tricky bit was finding where as the socket was immediately below the fuse unit, so it didn't look like an intermediate point was present.
To cut a long story short, the RCD on the circuit my dishwasher is on reduced the situation from me dying to having to apologise to my son for using a rude word. I would have died in one of those houses, i was sitting in a pile of water on the floor, reaching inside a dishwasher, way beyond my skill level in that I assumed internal parts would be insulated. Were they feck!
Wish all this info was available in 1966 apprentice years having to if necessary grovel for the unwritten law of sparking to get JIB grading “and pay , got it sorted,but left the trade a year later (21) for better money , time just flys “ like your videos about the game “ thanks
I had something like that happen to me about a month ago, the customer had swap two double sockets for two USB double sockets and connected the neutral and earth the wrong way round. My plug-in tester said everything was ok but the RCD would trip whenever anything was plugged into either of these two sockets.
How do manufacturers get away with these incompatibilities? In the rest of the EN-Area it's a fundamental selling point for electricians that stuff is compatible. Many manufacturers even picked it up as a selling point. If I were you I would avoid any manufacturer that builds lock-in traps.

Oh yes, almost forgot - 13:13 I bet the Tube will demonetize this one..! 🤣
You wouldn't want to be associated with this one - it's got nothing going for it with poor visial aids and the presence of Nick Bundy. Oh, and It'll probably get kerb-stomped by YT because of *that* scene.
@@dsesuk S'ok, we're only winding you up, you know we love you really 😘
Sorry for the multiple comments David, but we state 'if we can remedy any C1/C2 faults on the day, we will do so up to 100 pounds value' (landlords are ok with this). Some sparkies think this is a conflict of interest... but it isn't if you have an ounce of integrity (i think you have a few)
Human soup warmer on an RCBO. Just picture a nice little get together with neighbours (or swingers) in the hot tub - all getting zapped (no RCBO) and then the heating staying on for a couple of weeks while they all decompose into a sort of slow-cooked stew!! You need to get your animator (daughter) onto that image! 🤮
Nobody ever says it like that…..apart from you….but I’m happy to hear team Bundy …Nick & Adam shout it out , in more a youthful tone ….cheers though Dave & Nige …..and enjoy the coffee or beer 👍💪🇮🇲😉😂
Perhaps I'll set a new (and annoying) trend?
@@dsesukannoying , not necessarily new…..lol 👍😉🇮🇲
I’ve seen this problem before, it gave me such a bad head I had to drink a bottle of scotch…. Fucking brilliant video old trip.
Thanks for tuning in as always old spoon.
That estate is a carbon copy of a place called crompton acres in nottingham , same design , same shops same mem boards , are the walls straw by any chance
Fortunately not, although there is an estate in nearby Bearley that is straw walls. Actually Warwick Gates isn't too bad to work on - it's all block walls and dot & dab, so easy to cut in new accessories normally.
I really enjoy these videos, awkward faults with an explanation as to the why's.
I'm glad someone else has as much passion for hating new builds as me. Goddamn greedy developers and corrupt and/or moronic local governments seem to be the norm now. Fuck other peopls quality of life, just cram them in, profit and quotas are all that matter. Never mind the actual humans who will live in them.
Also I'm not sure your editor is quite upto the job, I'm sure I saw a helmet in the mirror.
On a job yesterday and the supply to their garage was a swa cable that consisted of a 6mm brown 6 x1mm blue with 6mm earth. So neutral is connected via 6, 1mm cables. I have never seen this cable before.
Anyone here know if this is safe. The load should be shared but it's bizzare. I don't want to have to change the cable it's it's safe and sits correct with the regs but I can't find where it's stated otherwise.
Cheers to anyone that replies
It sounds like a concentric cable. I've only seen it once myself as a supply to a flat, but it is used in distribution to provide supplies to buildings as in this case.
That sounds like "split con". There is a single phase conductor in the middle and then this is surrounded by neutral and earth conductors, with the earths being bare and the neutrals being insulated. The idea being that someone who digs through the cable will hit a neutral or earth first. There is no seperate armour unlike SWA.
It's used by the DNOs for TN-S supplies. Strictly speaking I don't think it's compliant with BS7671 for underground work on the customers side because BS7671 (unlike the DNOs) considers neutral to be a live conductor.
What’s the update on crazy lady mate?! That really was the funniest shit I’ve seen in a year
No update from my point of view as I've heard nothing else from her, however I did hear from a local plumbing firm who'd also been on the receiving end of her wrath and from one of her neighbours who is taking her to court after being physically assaulted. I've also heard that this wasn't her house; it was her late mother's property. Karen lives in Coventry and this property has been empty for some time. The lass has problems!
BEfore carrying out extra work and charging extra to the customer, that you actually con sult with the customer first.
Yeah, I'm talking minor stuff - repairs or rejigs that take minutes like changing out an incorrectly rated breaker or replacing a broken accessory. Anything that takes real time would be noted on the report and quoted for separatly. Usually a phone call to the person ordering the report gets a quick clearance to proceed.
Eaton are all type A now. Amazing kit best tp&n boards made
Could have made each fused connection unit with RCD
Fixed ring has to be the dumbest thing ever (speaking as someone not really from that era) given that you would be omitting rcd protection to things that really need it ie appliances that deal with water and likely made of metal.
Agreed - and all for the sake of saving a few quid on a second RCBO!
RCD/RCBO off, or neutral disconnected at the swb, and a test lead to verify the earth polarity and continuity is the only way to test for this and is the first test you should do.
I come across this fault often when adding RCDss to existing circuits and all because people don't test properly.
Interconnected neutrals on separate lighting circuits where a two way is involved is a good cause of random RCD tripping that is hard to find.
I was trained to the 16th, RCDs were mostly only for sockets
The houses on that estate are mainly Memera or Tenby boards and, usually, it's only the sockets on an RCBO.
The RCBO probably tripped on the fixed appliance circuit so they moved it onto the downstairs lighting circuit.
@@alvina69 hah this is probably true
Great video. E-N faults drive you mad sometimes. I feel the same about kitchen fitters, particularly when they start telling you how you’re going to route the cables and site FCUs. Fuck off
I still use the little socket testers all the time. Just need to trip all PowerPoint's on the circuit. If it trips then it's wired correctly. Aussie earthing system though
I like those Fluke ones, got the US version as well.
? What is the rcd tripping current for sockets in Australia. I've heard that the value may be only 5 milliamps in USA.
my line manger was not happy about me putting pods on 6A lights , special locations but hay :0
Why are you using old colours on your diagrams?

Agree about Hager, overpriced crap.
I don't mind 'em chagring what they want, but I haven't got time for all the sparks who get dewy-eyed over Hager and insist that's all they fit. It's nothing special. In fact, it's sometimes downright rubbish.
@@dsesuk David, what does 'chagring' mean..? 😋
but you found it any other spark would have put the rcbo back to the hot tub and said F it and put it in the observations took the money and run straight to that kebab shop, great vid,
Ah, good ol' Plan B! It might have come to that, but we knew it had to be a N-E swap somwehere. The tricky bit was finding where as the socket was immediately below the fuse unit, so it didn't look like an intermediate point was present.
David Savery, best electrical channel ever so much better than that Bundy chap
To cut a long story short, the RCD on the circuit my dishwasher is on reduced the situation from me dying to having to apologise to my son for using a rude word. I would have died in one of those houses, i was sitting in a pile of water on the floor, reaching inside a dishwasher, way beyond my skill level in that I assumed internal parts would be insulated. Were they feck!
Wish all this info was available in 1966 apprentice years having to if necessary grovel for the unwritten law of sparking to get JIB grading “and pay , got it sorted,but left the trade a year later (21) for better money , time just flys “ like your videos about the game “ thanks
R1+R2 combined with an R1+Rn test carried out at all sockets would hav picked up the fault on dead testing.
I had something like that happen to me about a month ago, the customer had swap two double sockets for two USB double sockets and connected the neutral and earth the wrong way round. My plug-in tester said everything was ok but the RCD would trip whenever anything was plugged into either of these two sockets.
How do manufacturers get away with these incompatibilities? In the rest of the EN-Area it's a fundamental selling point for electricians that stuff is compatible. Many manufacturers even picked it up as a selling point. If I were you I would avoid any manufacturer that builds lock-in traps.
Gold at 13:10😂
Middle earth😂😂
Who's is the Triumph off to the right while you are having coffee with Nick Bundy?
That's Nigel's mid-life crisis.
@dsesuk Haaa hhhaaa, that helps explain the brick as well. I got a Blackbird when I had mine. Wife nearly divorced me. He just needs to get to the TT next year now.
You know it’s good when you watch it twice I couldn’t believe it first time round. O and by the way he looks and sounds like Greg Davies from the “inbetweeners” funny as f**k.
Everybody says that, trouble is I don't have a clue who Greg Davies is 😂
Google him he also has loads on TH-cam -
Fucking Legend !!!
Yes David we have all had that fault at one time or another 😯
Next time I will blame Nigel 😂😂😂😂
Love your antics 👍👍
