I'm not an electrician or needing electrical work and no idea how i ended up on this video but I've just watched the whole thing with great interest. Subbed lol 👍✊
Welcome to electrician RUclips
God bless your patience mate you litrally don't know what you're walking into
I used to be a cable jointer, to fit an earth wire to the cable, the best way is to strip back both steel tape armours, clean off the bituminous impregnated paper off the lead sheath. You then tie the earth wire to the sheath and using a blow torch and D metal you plumb the earth wire to the lead sheath and the other end goes into an earth block. Another method was to change the iron clad cut out for a new plastic modern one and the earth wire then went into the earth block connector on the new cut out. We used to strip these cables live by cutting off the lead sheath and then getting to the cores that were only covered in paper tape.
You could ring that through to the DNO(distribution) as an emergency job, they would attend on the day to fix the earthing problem
Wow. That violation is as seriouse as they come.
Diagnostic is half the solution, well done Del !!
Last extension i was called out to was wired in twin bell wire. Several two gang 13a sockets. Then found connected to the lighting circuit. I just powered down and advised the owner to contact the builder who installed it. No earth obviously.
My last neighbour called me around after they had a kitchen refit. MCB would not turn on for kitchen ring. All sockets in kitchen were dripping wet after tiling. So I pulled them all out to dry out. Next day when they were tidy and dry I put the sockets back in. MCB happy again. Noticed new mini strip lighting under wall units...wondered where they were powered...no plugs. Bell wire from the back of the cooker. Neighbour said leave it...they were professional kitchen fitters...they must know what they are doing. Absolutely flabbergasted.
That wouldn't surprise me at all... ive been sent to sort out many a " professional kitchen fitters " work. Joiners should stick to working with wood lol
They don't know what there doing
Still safer than installations i seen in some Asian countries .Thank God we got guys like you to keep us safe
What a job.... well done to sort that. Perhaps a TT earth system or old earth that used incoming metal water or gas 😳
The gods were shining on you that day del. I certainly wouldn't be hacking away at a pilc cable. Should have put in a temp earth electrode. Well done on sorting the customer out.
balls of Steel !!
There was no danger mate - he only removed the hessian. Under that it's 2 layers of steel tape armour and you won't get through that with a knife.
Del your braver than me I would have ran for the hills with that one 😂
I think it's because the lady seemed nice and had him back within a few days so there was no messing him about with price.
Even I know no earth is bad
Gotta love del talking about getting clips on a 12 inch crawl space when the job is already a nightmare without the clips! 🙈
Got to be doing ZS @ DB or ZE on the first visit especially if ZS at socket is to high
Beat me to it, 100% mate
Exactly
Another great vid Del. People have comments which suggest alternatives. With 22 hindsight and some assumption that their approach would be more appropriate. Fine. Debate is good. You fixed it still and it will stay fixed now !
Well done dell.on sticking with it.
Good on ya.
Well done Del, glad you managed to establish a CPC in there. Would be interested to see the finished article once you have been back and installed the new sockets.
Well done Del, you've got a nice way about you.
As a retired sparks of 50 years I have the exact same consumer unit in my house ,its a split board and the 2 rcds and mcbs come with the board ,the problem comes when An mcb develops an earth fault it will trip the rcd therefor disconnecting everything else covered by that rcd .so that sparks swapped the mcbs to rcbs so an earth fault on an individual circuit will only trip that circuit and not multiple circuits but he should have spotted that there was no main earth cable
He definitely should .
Del is the man!
He really is .. Unbelievable electrician isn't he
Great work Del, but why didn’t you get that lady from your last job around , she would have talk you through fixing the problems in no time 🤣
Haha
legend has it she’s still talking
Man you've got some patience....confirms why I ditched domestic sparkying a long time ago ...fair play to you for taking the job on. 👍
Agreed. I do purely industrial electrics these days.
@@garrett69 What’s the problem with domestic?
butchered CU is an understatement ..... wow... great video
Did my 2391 as part of my training. Was surprised that there was sparks out there without it. Plus there fault finding was 💩 because of it. No wonder that we have installs like this.
Great video delroy big fan of yours keep up the good work 👍
Cheers Kristian. Thanks for the kind words
Always amazing what you find! At least it's safer now!
Yep, there's always something new to find
@@eastwayelectrical You should see the delights im working on right now! 😳🤯🤣🤣🤣
18:33 I started sweating and had a panic attack !!! Old TT system obviously and the earth, as you suspected, must have been an incoming water or to a stake somewhere.
or probably corroded away somewhere as earth clamp's do
Crazy del your a brave man fitting that clamp to the sheath. Certainly one for the DNO. If u you out work live I would have had CAT rated arc gear on, like we do in the USA. With double insulated rates gloves, face shield and fire rated clothing. No simple jobs for you Del. Get yourself a metabo chaser well worth the investment.
I agree. Not a risk I'd take. That said, a pal of mine who works for the board did the same thing as a temporary fix for me years ago. Shaved off a bit of the lead sheath & replaced the clamp that was on there for a braided TNS connection. Thing is, he'd worked for the board for many years & was qualified to work on it. I've since paid to have the meter relocated outside & they put in a TN-C-S earth. I do not recommend anyone tries this fix, even as a temporary measure!
There was no danger lol, it's got 2 layers of steel tape armour and that's what he temp connected to.
Up until the 1950's, many electric systems here in Canada were unearthed; there wasn't even an earth wire.
That's mad. Just shows how much the industry has advanced.
Think a Ze test at the start may have been an idea del 😂 good temp fix though. Wasnt expecting as good a reading as you got 👍
And that is why we use conduit to run electrical trough here in Switzerland.
theres a good chance that house was built before electrcity was supplied to houses
That's why we use tubing inside the walls all the time (it's mandatory), so you can always change, modify or repair any wiring if necessary.
It's anyway really strange to see the differences in wiring between different countries. We never use rings and all our houses and flats are always three phase (3x400 Volts, so 230V per Phase)
Typically it's a lot cheaper on the copper to just have a ring circuit
@@thepenguin9In 1950, maybe...? Nowadays its not even 10% of the bill. Did you ever check the price of those gourmet/designer outlets and switches people put in their homes?
Appreciate the videos. What a lad!
Good job del I had a similar job like that last week downstairs sockects and 1 room upstairs wired together the the circuit was tripping every 8 or 9 hours I plugged sockect tester on some of them it was showing me live and neutral reverse but checked every sockect the connections was ok I thing there’s a joint underneath the floorboard the faults coming from I can’t lift floor he’s got new flooring I said u need to rewire the ring and separate upstairs room to radial big job now gave price for it iam not taking a chance very dodgy wiring
Ey up, just a heads up you should really remove the steal banding and connect the earth clamp directly to the lead inner sheath on the main. Will help reduce the Ze. Any earths better than no earth tho Del.
I like the old metalclad ISCO cut out.
Is the Cooker hood ok? I was just thinking as it was close to the faulty sockets.
Also if you had 36.5 ohms at the sockets on Zs is the Main earthing arrangement a TT system?
I've had it at a property where the main earth was wired to the cutout MET terminal as TNC-S but it wasnt connected inside the cutout on the Dno side.
Respect for staying power man...there's probably been spurs feeding rings feeding cookers. No earth??? customer should be glad you spotted that one .
In my previous house it happened exactly same NO EARTH connection! I only found out after 12 years living in it and thank GOD nothing bad happened. At the time I was going to night college for the C&G 2330 level 2 I asked my tutor and he told me to have it rectify immediately which I did.Thank to my good teacher too.
Crazy story
Yep she understood everything....
Nice job so far delroy. Interested to see how you get the cables to the kitchen sockets without wrecking the tiles
I don't think there's anything you can do, unless that wall's plasterboard. Apart from that it's either take the tiles off or go trunking with pattress boxes.
I was looking through the gap in my fingers when he was rubbing his knife on the main cable 🤣⚡
Great video
I always try to make a point of checking the earthing & supply arrangements first, otherwise you just end up chasing your tail. Once I know that the earth is satisfactory at the supply end I will move on & do the fault finding at circuit level, it never ceases to amaze me how often I come across a bad main earth!
Nice job Del 1thing the tv socket cable when it goes over the top of tv bracket it’s not with in the zone if you had gone left out of low level socket and the straight up to tv you would have been ok
Nice sharing...
That Cowboy Sparky who did all that should be in jail for such a crime of a job in the sparky world! Good job on the fix Delroy!
Sparky?!? Ha, that has 'Builder' written all over it! 😵
Mate you always get these crazy jobs hahaha
Tell me about it
Poor woman had to pay twice but at least you sussed it ,good job
Could possibly have been a TT, with the gas and water bonding looped of that earth clamp above the DB. He hasn’t kept it continuous though and looks like 6mm from the clamp.
best sparky on youtube ,
Thanks sir!
I am so surprised how often you come across the cables failing, I have never come across cables/wires failing. unless it is due to mechanical damage. most of the time a faulty on the usage end.
Del didn't hear you ask her "have you done anything to your house before this started" 9x10 they did and that's the problem very strange to get that many faults for no reason over night
Looking at the quality of the work there id guess there's a toasty junction box under the floor somewhere
Very nice video`s!
If there is rcd protection then a loop reading of 36 ohm's is not a reason to disconnect the power
It's unsafe with an inadequate means of earthing
How are you sooo relaxed... that was a nightmare!
need to stay calm no matter what or you cant think straight
I suppose one saving grace about these old houses is you can get underneath everything to work on it.
I'm not a qualified electrician but my understanding was that those metal straps used for water/gas bonding are not suitable for PILC cables? Lead is a much softer metal so if you over tighten you can easily crush the live cables within. Same reason why you don't use them to earth the steel sheath on SWA. Or maybe I'm wrong? Very open to correction as I'm still learning.
I suggest you qualify as an electrician before commenting on things you know nothing about
Not a spark, but I'd have thought you'd have had to call the DNO on that one - That main incomer is ancient!
defo an earth clamp for a main earth on a old cable like that mmmm
Your opinion means nothing unless you are a qualified electrician
@@adamsharp201 Ok...
Jonathan 100% correct
Another great watch Delroy, keep them coming.
Great work Del, and fantastic, chilled attitude and approach.
Still think it's a terrible system putting the wires in the wall like that. Over here everything is put in 16 or 19 mm PVC pipe. So if there is any fault you can replace the wiring. I do like the switched and seperately fused outlets.
If US & UK standards got together & combined the best elements of both, it would be the envy of the world. As it is, we both have our own peculiar set of deficiencies.
The DNO won’t provide an earth as it’s a Pilc service and are not required to provide one. The only options would be an earth stake or request a new a PME service.
@@totherarf sorry but maybe you didn’t understand. Why would the DNO refuse you a new PME service if you’re happy to pay for one? ie £4000
It really makes no difference TNS or PME. The network is all PME. That sheath is still connected to neutral in the joint.
did the rcb trip when hitting the test button?
Brave man fitting a bonding clamp onto PILC! could you get the DNO to PME it ?
@@fromthetoon1602 Same here,DNO would have also upgraded cutout.
I think Delroy said it was all temporary.
Oh maybe. At least Ze must be down to a reasonable value now so it’s much safer than it was.
@Dusty 99 you aren't allowed to touch the pilc coming into the property as a normal spark, dodge city. Phone the dno and they will put an earth sweat for the customer for free.
It's a DNO issue
John wayne must have wired that lot up 😂😂😂
Man as a sparky in the Netherlands i'm crying right now!! we only use PVC pipes put into the wall so that the wires can always be accesed or removed. The owner having to fuck all the walls up must have been so painful and costly. Is this UK standard?
If you were getting the same readings on the old cables does that mean the lack of main earth was the problem all along or did I miss something?
Installed by a part p kitchen fitter no doubt..
This doesn’t surprise me , I meet one Romanian electrician who did 500V DC insulation resistant test without disconnecting the load and was keep asking why he had low IR test results . He blowed up fridge and microwave 🤫
Quality 😂
Solid work as always Del. Hope you're keeping well mate.
Cheers MMG, very well thanks. How are you?
Did they had outdoor lamps on that circuit?
Not a spark but enjoy the vids so apologies if this is a daft question...If the earth was non existent originally, was the remedial work on all the sockets truly necessary? Sort the earthing, kitchen and living room in turn sorted? I may be missing something not explained but that's how I took the video after all that.
I'm not a spark either but I think the tripping was due to the faulty wiring and the fact there wasn't a reliable earth was just another problem on top of that, not the cause of the tripping. I could be wrong.
Both comments are accurate but mean nothing if you aren't a fully qualified electrician. Stick to your day job.
@@adamsharp201 What's yours? Trolling on YT? Nothing wrong with asking questions
That amount of damaged cable sounds like either crushed cables, or seriously dodgey junction box
They both RCDs double pole is RCCB and slim one is RCBO
Great video Del,not sure if your supposed to clamp on to the sheath like that,shouldn’t the DNO be called to install an earth?and the chase going across to your high level tv socket is not in a zone,did you find where all them cables went to in the kitchen?3 cables in each socket and most of them down crazy,the last Electrician wants putting in prison before he kills someone.
Hi ask the DNO to provide an earth they will strip the armour exposing the lead underneath and bond the lead and armours to an earth block. Using the armours alone is the old method and earth may be lost if they corrode at any point.
i was think that it's now you have damaged DNO's property it's there cable it's not on our side to just scrape away & hack at there cable
Either originally a TT system or they used the water mains as the main earth .
Really common ....I change them everyday
@@daviej8180 always call the dno its a no charge repair and thier ilability do it yourself and an issue occurs its your nuts on the grill
@@steverobinson8170 I am the dno
@@steverobinson8170 and it does my nut right in when folk stick a bonding clamp on ...most of the time they dont realise the lead is the earth and no the armours
@@steverobinson8170 The DNO will charge for a PME connection, unless there is an existing TNS or TN-C-S that they installed, in which case they're responsible for maintaining it. I'm also DNO. It's possible different regions have different policies on this though.
Hard one to sort out, but we'll done
Thanks Steven
Call the DNO to provide a proper earth. Of the lead sheath, not the armour :-)
Tiled floor AND a laminate floor.... my worst nightmare .. however, having bad readings on most of the cables whilst disconnected from each other does seem a bit odd.
Flippin ek Del!
Your a brave man messing with that PILSSWA.
Well done for sorting it but me personally I'd have batted that right back to the DNO.
Absolutely
thumbs-up 👆
It probably was TT before.
As an electrical engineer and electrician, i will get nightmares from this
What on earth is going on with that left hand RCD being used as as a connector block? It looked like there was a neutral joined to the phase of the 32a breaker next to it...
1 is likely being used as a 20 amp fuse
why can you see the buss bar -any reason Del ?
That clamp may come loose over time, or high resistance over time especially if lead jacket. Need an earth rod as well.
defo
I'm not an electrician, so have no idea what you said. But, from how it looked in the consumer unit I guess it was really really bad.
3:12 LOOK AT THE BUS BAR!!
sir electrician iti diplom haus wairing me what work videsh i vecancy plz
He who dares, wins. Eh, Del?
A fire hazards, l can't believe this, they left a fire hazards. 😳
Spirit orbs.
0.8 max tns system Surly that supply authority issue I wouldn’t have left it like that
Hi delroy I never saw a split load with rccbos madnesses crazy
Hehehe, i had a bad earth, 2 light sockets, 3 feet apart, 11 megaohms resistance between the patress box..
I'd like to see what happened next
Aggghh - ring circuit faults 😩
Earth's depends on what system it TNS. TN-C-S or TT normally sweated on 10min job for the authorities and they make a fortune in feez
