- We are excited to share a breakthrough innovation in electrical cables - the EarthSure cable from Doncaster Cables.
Gone are the days of struggling with sleeving over the earth wire on Twin & Earth Cables. The EarthSure cable is the solution that electricians have been waiting for. This revolutionary cable looks like regular Twin & Earth but is now equipped with a fully-sleeved earth conductor.
What's truly remarkable about the EarthSure cable is that it maintains the exact dimensions, performance, and approvals of regular BS6004 T&E cables. Electricians can easily incorporate it into their existing installations without the additional hassle of earth-sleeving.
In this exclusive video, our Gary Hayers sits down with Aaron Walstow from Doncaster Cables to discuss how they overcame the challenges and designed this groundbreaking cable.
The EarthSure cable is a game-changer in the industry and is sure to become a favorite among electricians.

I'm just a DIYer, but i think I speak for most people who ever need to touch electrics, Thank you so much for this. Its about damn time. I've never understood why the CPC didn't have a sheath if you always have to apply one when you strip the cable back.
I always assumed the cpc didn’t have a sheath so that it was not insulated from potential damage to the cable?
It's cost related and also if you were to drill through the cable with a screw, when say putting up brackets for a shelf,you would have a higher chance of hitting the earth and one of the line conductors to cause a safe path for the electricity instead of making the screw live
The CPC doesn't have insulation because it doesn't need it. It is surrounded by the cable sheath and the two adjacent conductors are insulated so there is nothing for the earth conductor to come electrically into contact with anything else.
Therefore the cable can be made more cheaply.
When analysing problems in electricity, you have to ask yourself: what's the electric shock risk posed by what we're doing, and what is the fire risk posed by doing something?
And the answer here to both questions is: nothing.
You don't always apply a sheath when you strip it back. That is not correct.
There are two different things going on. Insulation and marking.
The line and neutral are covered and that is insulation. The purpose of insulation is to ensure that no electrical contact can be made from the inner copper conductor and anything else.
Marking is where we apply a piece of coloured sleeve over the conductor and the colour of the sleeve indicates the purpose of that conductor. This is NOT insulation. The sleeve might have some electrically insulative property but it is much thinner than the insulation that is used for the line and neutral. It does not offer the same level of insulative protection.
You are assuming that the sleeve (which is typically yellow) that is put on the earth conductor is being done to provide insulation. That is not the case.
When you have a bare conductor wired in, someone else coming along later after it was installed, doesn't know what that conductor is carrying or what its purpose is, so you mark it.
@@deang5622the whole condescending explanation of the difference between insulation and marking is completely irrelevant to your first sentence. You do, in fact, always apply a sheath when you strip it back. Not insulation, but you do apply a marking sheath.
It's a bit bizzare watching this from Australia. Our twin and earth started coming with sleeved earth probably 20-30 years ago. Only find the bare earth in pretty old homes now. Surprised it's taken this long for you lot to take it up!
We also moved away from solid conductors in everything apart from 1mm. Stranded is a lot nicer to work with.
Thanks for your insight from Australia and watching 👍🏻
Yes, while we do have the option of using solid if we like, stranded is just so much easier to handle and pull than solid that no one in their right mind does.
I’ll agree completely on the stranded vs solid but is it much of a difference having a sleeved CPC?
@12000gp Easier to work with, don't have to carry sleeving with you or have it fall off and all that jazz.
If you're going to sleeve it when you terminate the cable, why not just sleeve it at the factory? That and all our earths are required to be stranded, and sleeving that is more annoying.
To me, the only situation where leaving it bare would make sense is where you don't need to sleeve it. However, as that's mandatory, what advantages does a bare CPC have?
@@Thermoelectric7 The usual explanation is that it gives better protection should someone drive a nail through the cable, ie higher probability of contacting the earth wire should active/neutral be nicked. It's a stretch at best.
Finally the UK has caught up with Republic of Ireland! The hours of sleeving you're going to save!
Meanwhile in USA...
Earth ground is bare and they let it touch anywhere it happens to get pressed against.
It's been that way 80-ish years when they started putting earth ground conductor within a jacketed cable.

When there even _is_ an earth.
@@benjurqunov Meanwhile in Central Europe, we always use 3 identical conductors for L, N and PE.
You had me laughing as I watched the earth sleeve drop and thought, 'Yep, been there, just a few times' 😏😎🖖
Especially when it's dark because the electrics are off!
Australian here: We have had a dedicated Earth sheath in green-yellow in our 2.5 amd 1.5mm squared T.P.S., (Tough PVC Sheath) cables for about 30 years now, prior to that, the Earth was bare as in your cable.
Some differences/developments in our cables.
1920s Vulcanized India Rubber and cotton sheathed single solid core wire in imperial…about 2mm squared, lain in pine trunking. Imported from England, so identical to yours. Earth run seperately, if st all.
1930s. Same VIR in black painted, rolled steel conduit. Earth still run seprately.
Also, in a similar form to modern, Lead, yes, lead, the 84th element on the perioic table…shearhed cable, with the same VIR inside in red and black. Red colour was rather dull compared to modern polymers.
1940s. War surplous black rubber. Same flat format as modern, no Earth, (Run separately alongside, if at all). Inner cores, soft rubber that tended to bobd to the outer black sheath. No cotton weave over the rubber inners.
All these older cables had single solid cores that were tin plated copper. I think the tin was put there because the bare copper would react with the sulphur in the rubber.
1950s. First PVC insulated cables. Two cores in vivid red and black in a black sheath with a “score” on the wide side making it look like thick “figure-8”. Conductors: Still single solid, but now without the tin plating.
1960’s. First like the black ‘50’s stuff, but now in white. Somewhat later the bare Earth was added between the red active and blue neutral….so really similar to the stuff you use there now!
1970’s. Earth was made stranded, first three strands, later increased to seven strands. ALL AUSTRALIAN CABLES for donestic wiring have an Earth conductor with the same cross-sectional-area as the main active and neutral!
Much of the remainder of the 20th century: Things stayed much the same, however the Government made a decree thst all public buildings be wired with cable that had all three conductors seven stranded, do cable with this stipulation was manufactired and it could be used for domestic rewires too if desired, but it was more expensive.
Turn of the Millenium: Sometime sround the turn of the Millenium the gree-yellow sheath was added to the centre Earth core and the use of single-solid cores was banned and ALL cables had to be seven stranded. It has been much like thst ever since.
So far, that European “madness” of brown acrive and blue neutral….which gets confused with blue phase in three phase stuff…has not infected us….yet…and hopefully NEVER! Our single phase active/phase colour is still RED = DANGER and Black = absence of all colour = absense of voltage (under normsl conditions). And don’t even mention that American craziness, BLACK = acrive and WHITE = neutral…what sort of madness is that. Theor heads must have been put on backwards!
Here, white is a switched active in a lighting circuit between a switch and a light or sometimes some other load.
Our modern TPS has two paralell scores down each side to facilitate tearing it back to reveal the inners, the older stuff without the seperately dheathed Earth had just ine score on each side.
New Zealand cable is identical…but with one difference…the active is in the middle and shielded by the neutral on one dide and the Earth on the other (both connected by the M.E.N. Link in the switchboard. (Kiwis were and still are just one step ahaid of us Aussies!)
Our cable brands are Pirelli, Olex and Advance Cables.
The newest cables have layered insulation on the active and neutral inners that is white closest to the copper strands and has a layer of red or black over the white. The Earth is green with s two thinner yellow traces, these colours extend right through to the copper cores.
Cheers to those st Doncaster Cables, hope it gives you some ideas for further improvment.
P.S. All our goodbrands have chalk dust between the inner and outer. We are dtrating to see fake Chinese clones invade our market with dire consiquences.

No-one is immune from criticism, but criticism should be deserved and constructive. I don't think your comment fits those criteria. Moreover, the motivation of electricians everywhere is safety to them and the consumer. Blue and brown causes no problems for the decades they've been the standard in the UK. Either you know what you're doing, or you should leave electrics alone.
Spellcheck my dude. Or stop youtubing while drunk.
That "European madness" as you call it was introduced to Aus/NZ Standard 3000 in 2018. The old colours are still permitted (AS/NZS 3000:2018 permits active to be any colour except green, yellow, green+yellow, black or light blue, permits black OR light blue as neutral, and mandates earth must be green+yellow). But the recommended colours are brown for live and light blue for neutral. Three-phase colours are brown for P1, black for P2, and white or grey for P3. Yes, we have black for a live in three phase now.
I like to think of it like this: the brown wire is the same colour your pants will become if you touch it.
We changed to brown live / blue neutral for European Harmonisation e.g. in Germany red used to be the earth - as red = danger this may sound crazy but it's lateral thinking...what causes the greatest danger if it's not connected? The earth wire! The load would work normally without an earth, you only find out it has not been connected when you get an earth fault which electrocutes you.
I agree about the mix-up of blue phase and blue neutral; back in 2003 colleagues of mine were doing an install and connected the blue neutral cable in the equipment (which had been manufactured for years using European colours so nothing new there) to the end of the blue cable that had been installed by the electrician...BANG!😳😳😳
Hallelujah, About bloomin’ time. We’ve had this type of cable for years in Australia and New Zealand. How many times have you sparky’s put oversized sleeving on the earth core,I wonder!
Also in Denmark
You're cabling are the worst dude
@@BurkenProductions Your spelling is the worst
Brilliant idea. The comment about dropping the sleeving is so true- usually when I've been on a stepladder.
So this idea has a safety benefit attached too!
This is groundbreaking stuff Doncaster cable for cable in England. Ireland had this years ago. This product will change the uk market. Well done team Doncaster cable
Same in Oz
Most of Europe never allowed this bullshit. Even early 1960s cables had full sized and insulated ground wire.
Same in continental Europe ... 🤷♂
The UK is a 3rd world country compared to continental Europe. They have ugly electrics and they use miles instead of kilometers. Far from modern civilization.
This is a no brainer. The original spec should have mandated a sheathed earth conductor.
New in UK. In Germany since 50 Years.
i thought the same
Hey don't be mean! I mean I saw a lot of those old 180° spring loaded turning switches in the UK too, almost felt like a Victorian rich person adjusting the gas flow in my modern gas supplied London Estate lighting.
@@jonasduell9953 :D
also the uk has smaller thickness wire for earth. that's forbidden in belgium
@@louisvl10 I would think it depends. Here in Germany, it can be smaller for conductors >16mm²
Australian PVC twin and earth has had the earth (CPC) fully insulated since before I became experienced with it in the mid 1970's, i.e. originally green but more recently yellow green insulation the same overall thickness as the active and neutral lines insulation. Also our earth cable itself is the same cross section and material as the active and neutral cables for cables up to 4mmsq, after that the earth cable can be reduced cross section. Personally can see the benefit, but can't understand the hoopla about a leap that brings the UK up to standards that have existed elsewhere for 50+ yeas.
We have had this in 🇮🇪 for years with the exception the CPC is the same size as the other conductors.
👍🏻👍🏻👍🏻
UK is one step closed to IEC standards, and less hamonisation will be required.
Same in Australia…..we had this cable for years
@@Ivorbiggin At least 30 years.... I was an apprentice almost that long ago, and the only time I have ever seen cables like this it is in old installations.
@heffo1992 i wish the cpc was the same size, looks like this is still a 2.5mm and 1mm. 😭
In Switzerland and the rest of Europe, we have „NYM“ cables for permanent installations. They all have 3 or 5 equally sized strains, of course with the right colors. Don’t understand how England is so behind in that regard😂
Same I was confused by all the hype, this has existed in Australia for over a decade at least.
And all that stupid color coding with heat shrink, here in germany you can get basically every combination of brown, black, gray, blue and green/yellow, or numbered black you’ll ever need, and usually up to 10 conductors, as NYM, NHXMH, NYY, N2YY or NYCWY, NA2YY and NAYY for >10mm2
But you have the absolutely terrible colour choices that you forced on us.
UK has always been an incredibly price sensitive market for domestic stuff, in commercial there’s not so much T&E and yeah we have all sorts of other cables too….
As an Apprentice Electrician working at a cable manaufacturing plant (not doncaster) love seeing these videos.
How ground breaking 😂 New Zealand and Australia have had this for years. Years ago when I did my part P in the UK even the instructor had no clue as to why the UK was so far behind on this. Glad your now catching up 👍
Very exciting for our industry 👏🏼
Sure is
Is it that exciting? How many seconds will it save?
Continue using the none sleeved version. Thats that sorted
Hi Efixx in disguise.
What about the poor sleeving production companies. Think of the millions of unemployed this will create (just a joke, in case that slipped you by).
A Notification come thou, said to myself I’ll watch it later when I get home like I always do but re read it when I get in the van and watched it straight away
Nice game changer that for us 👌🏼👌🏼🙌🏼🙌🏼
What a revolution. Good to see you pommies are finally catching up. Australia introduced this back in the late 70's.😂😂
pointless - solving a problem that doesn't exist. Zero people have ever been killed by an uninsulated earth - which by definition, shouldn't be insulated.
Next, notices warning that water is wet and ice is slippery...
Wait what? The UK finally has isolated ground wires?
In germany you are not allowed to use anything besides double isolated wires in house wiring.
The UK have had "some sort of" democracy for several centuries.. until they are ahead of the pack again it will be a while and needs to break. Only then will that society be able to keep up or even lead again.. this is (unfortunately) to be expected.
I just love Doncaster cable. I had to use some cheap Indian cable a few weeks ago - what a difference. Great news, not enough wholesalers sell DC
👍🏻👍🏻
We would agree... but maybe slightly bias! 😃Thank you for the nice comment and support.
Toolstation sell DC
@@Doncaster_Cablesdoes the Earthsure design reduce the likelihood of cable damage/penetration causing a current path to the CPC in order to cause tripping, or has it been designed so this remains the same? Presumably we don't want to reduce the likelihood of cable damage resulting in an ADS...
Thanks Gary you have score us all a winner and Doncaster cables trying to take all the glory. 😁
He is always trying to take the credit for other people’s ideas 🤣
It's a lie, was my idea! #alternativetruths

Lol, yeah, I know @@cglees
I thought in Belgium things went slow . We have this for decades ! 😉
Here in NZ, we have been using green-yellow sleeved Earth wires in our TPS (Tough Plastic Sheath) cables for many decades, originally in Live, Earth, Neutral order but now in Neutral, Live and Earth order (which I guess is probably safer given that Live is in the middle and RCDs/GFCIs are ubiquitous and would quickly detect a Neutral-Earth swap).
TPS= Thermoplastic Sheathed
@@jackfromthe60s: TPS as “Tough Plastic Sheath” is common in New Zealand written material (for example, that put out by WorkSafe, a government agency). I gather it’s because we used to have TRS = Tough Rubber Sheath, in contrast to the VIR (Vucanised Indian Rubber), which still exists in the death trap houses owned by slumlords.
Thanks, now to extend the socket circuit with this cable. Which will confuse my dad who will disapprove the whole project on its own but its worth it as he will tell his friends about it.
I was told at college, that the CPC was unsleeved to help with ADS if the cable is damaged, as it would be easier for it to come into contact with the line and neutral conductors and activate the protective device 🤔
this is exactly what I was going to say, if you put a screw through T&E all it has to do is touch earth, but if the earths already sleeved it might gently push it put the way. Not sold on this for my house, I might put it in a commercial building
Hooray. I thought the exposed copper E was to ensure that if the cable fractured and the L & N were exposed they would touch the E first. But to have the E not needing the sleeve is so good. Many times I go to my box and cannot find the sleeving! Hopefully it will be stocked by B&Q and Screwfix soon.
It doesn't ensure it, it might raise the odds - but I suspect it almost never happens in the real world. You're better of just having RCBOs/AFDDs and an occasional circuit test. If you think if you stretch the cable or bend the cable and it damages the conductor the insulation of the conductors will force them away from each other regardless, best you can hope for is the cable fails completely or an AFDD spots it.
Wow well done truly innovative, my only slight concern is how it performs stripping the cable by pulling the CPC that so many of us are used to doing especially when the cable gets a bit old and the powder does not work as well.. Apart from that I would say if its the same price, just stop making the old T&E and have this as standard, it will be down to the wholesalers, not enough people will hear about this whereas if you just replace all your T&E with this when the sparky gets it and sees the surprise of cpc colour coded they will be like wow this is great cable ill make sure I get the doncaster cable again as thats great.. But most sparkies will just grab what the wholesaler has in stock..
I am not a Brit, just a EU engineer. This video popped up on my YT feed. If I understand, British electricians need to strip the 3-wire cable, then artificially put a yellow/green sleeve on the earth conductor that runs otherwise bare? And this company has designed a cable that fits the existing standards, but runs the earth insulated with a "pale mauve" color? (not sure i can identify this correctly in english)
Yes, other than the colour of the insulation, which is normal green-and-yellow striped.
this is standard in the EU for like 50 years
I didn't even know these cables aren't the standard in the EU, here they are used for most part of past 30 years
wow tbh a small but quite pleasant change to ffs I've drop the sleeve. again !!
I think I speak for everyone when I say, IT'S ABOUT BLOODY TIME!!
I'm just a DIYer and son of an electrian and whenever we strip the cable back we have to apply earth sleeving on anyway so why not have the earth identified anyway??
The amount of faff and hassle saved from dropping earth sleving will be emmense!
And having it at the same price as T+E means just buy earth sure!
Absolute game changer!! ❤
What a time to be alive.
Nice to hear 🙏
😂😂😂😂😂
When you're alive is always the best time to be alive. Some might say the *only* time.
Or for that matter, what a time to be a CPC. I'll get me coat.
Well done guys again, masters at work. Well done on keeping same price, that is amazing.
Thanks for the wonderful comment 👍🏻
Great Stuff !!!
👍🏻
Living in a country which uses NYM-J cable i always wondered why twin and earth used bare copper as earth conductor. Nice to see that there is some progress.
I was in a big DIY store in Germany recently - NYM-J was on the shelf in all the sizes, looked like a nice product.
Somebody had to spend the R&D & Certification money at some point, even Irland have had something similar for years. Well done Doncaster Cables and best wishes for the sales of it.
Even as a DIYer this is exciting! 😍
Very nice, must get some.
Let’s us know how you get on 👍🏻
About time too. I'll be buying this.
Glad to see it made in Britain!
Awesome product
Thanks
I've wished for this for 50 years (now retired) . I used to use 1mm t&e with 2 red cores for switch drops, but haven't seen it for a long time, maybe DC should bring it back with 2 brown cores. Taking it even further-how about 3c and e with 2 brown and 1 blue, for timer fans/PIR etc. I always hated silly bits of sleeving.
Agreed on all points. We do still manufacture twin brown ordinary t&e. Nothing stopping us bringing a twin brown Earthsure to the market if it helps people 👌
Bought some the other day with 2 brown cores by mistake... Prysmian though not Doncaster
This is a great product, it will be welcomed by many
I wonder if 4 core flex will ever be improved by having a blue core instead of a grey core - like we used to have before harmonisation? It's a pain sleeving or taping that grey in roses, plugs, and other lighting accessories.
And we don't use 1mm 4 core in 3-phase no-neutral applications as suggested by the grey core.
@@FirstDan2000 In Germany you can get four-core with a blue on special order I think. Not sure about flex but I've definitely seen building cable. It's not needed all that often though and due to low sales volume five-core can actually be cheaper than four-core.
Most people might take the neutral to the switch Nowadays surely.
I do and I only install radials.
Crazy I know. 😊
Everybody in the UK will be speccing this immediately :) What a great idea :)
That's brilliant
Thanks for watching and commenting
Brilliant well done
I wondered how long it would take for the Uk to catch up with the Republic of Ireland who have Green/Yellow sleeved Earth in their T&E for some time now BTW they don't appear to have problems with cable clips etc. It has been a long time coming I'm 81 and a long time retired, we would have welcomed this in my day, in my time we called it Earth or Ground and not some silly acronym that has been used for a component supply company for many years & a lorry drivers exam, just Google CPC and see what you get..
It was called cpc to avoid confusing the earth conductor from the circuit protective conductor.
so the UK is starting to do what we have over here for many years. however our cables are round (XMvK/YMvK which is most common) all conductors are the same size. never understood why it is blank over there, or smaller sized to the main conductors. Our regulations say that the Protective Earth must be the same conductor size as the main conductors up to 16mm2 above this it may be half of the main conductor size. we see this usually in steel armored (YMvK-AS) to be installed in the ground. Steel armored is only used in the ground to act as an extra mechanical protection, with the PE conductor consisting in bare copper strips (with additional steel strips as filler and reinforcement) or flexible tinned core with a braided steel mesh around it.
Love this, but I’ve only recently discovered the Quickwire products (thanks to your videos) and love them! Will these still be compatible with this Earthsure cable?
will be interesting to see a video on what this new cable is like to work with, i.e how well does it bend what is it like to strip. how easy is it to connect the fiddley earth into a pendant where most of us over sleeve all cpc's together. also now I can see the sales of wago's going up on light switches with cavity/fast fix boxes ( where you feed the switch obviously ). Also how many times have kitchen fitters drilled though a cable and nipped the live and cpc together now they may screw into the live but not break the insulation on the cpc which would leave a nice live screw in Mrs Smiths wall unit. Not sure if I like this cable yet only time will tell I suppose
So I guess the big deal is that the cables share dimensions with the regular ones and of course the approval. We had cables with sleeved earth for longer than I live, but those are round with equal distribution, so they would not fit your standard components. Being able to use existing tools, switches and other components is quite important in the industry. Greetings from Germany.
As marine Electro Tech, all our cable comes with sheathed earth. Never understood why domestic stuff doesn’t 😂
The equivalent of T&E in the USA (Type NM-B, commonly called "Romex") is also bare copper for the CPC (Equipment Grounding Conductor, usually just called "Ground") is always bare copper in my experience. The difference is that there is no requirement to sleeve or label the EGC in the US National Electric Code. The EGC can be bare copper, solid green, or green with a yellow stripe.
Wouldn't you want it to always be bare in case someone drives a screw into it. You want the ground to sink the current immediately if a short is possible
@@__Brandon__ Exactly, I do not understand the European desire to insulate ground. More over, since we are all still alive in North America, it looks like all this largely irrelevant, and just serves purpose to have extra regulation.
Nice idea, but one small disadvantage, if you pull the bare earth wire hard, it simply cuts thru the outer insulation, helping stripping time.
Nice to see that the new pre-sleeved will cost the same 🙌
For some further historical debate on T&E - GB patent GB834015 from June 1956, suggests the use of an unsleeved CPC is to facilitate the splitting of the sheath - for use as a ( to quote) "rip cord"! 😀
a very good idea 😊
Great idea, if it's the same price and quality, this should be used as standard!
Insulation doesn't come free, the price will have to rise.
Game changer 💪👍
We thinks so 👍🏻
I’ve always said prysmian cable is the best to work with but if these new earth sure Doncaster cables are any good I might switch. 😮
Wonder if the new quickwire connectors are affected with this?
Absolutely cracking
Not an electrician but I always wondered why the earth cables in the UK didn't come with the insulation already applied. My hypothesis was that it was a safety feature that'd make sure if the insulation on the live or neutral would ever get damaged, it'd short to earth and trip the fuse. Kinda surprised to hear the earth cable is naked just to save on material.
Goes to show me not to overthink stuff.
Why is the ground conductor thinner in UK? It should be at least the size of the phase/neutral
Great move from Doncaster matching te price for ordinary, who is going to buy old style now this is here other manufacturers got some catching up to do.
Thanks for the positive comment 👍🏻
That I would imagine is because Doncaster Cables are anticipating covering the development costs through increased sales. They may well have patents making it difficult for other manufacturers to follow.
You won't be able to use the cpc to split back the insulation anymore......:)
Been like that in Germany for DECADES.. and over here in Australia this is the norm for at least as long as well. And the UK only catching up now? OK, in the grand scheme of things - a couple decades give or take don't really matter.. but wow.
My only question now is does it work with the quickwore junction boxes you feautred before? 🤔
Was fitting this cable with covered earth in Australia in 2008/09. It's not NEW just never been offered here we're catching up at last !!
Can this cable be used alongside the Quickwire T connectors?
As a German i would say we have this since the 60s/70s. Even in this old buildings where cables were placed underneath the wall Finish without ductwork around them. So save to say Ive never Seen anything Else in ny life used.
So ofcourse we have single strain wires too. But in a context of your everyday Electro Installation this Basic 3x1,5m^2 etc is the Most Basic thing
Are you going to do a low smoke version?
Interesting. Yes, it will mean having to learn/get the habit of stripping the outer sheath differently. With a bare CPC I usually use the end-run method, cutting in lengthways from the cut end, running next to the CPC as a guide and pushing away from the adjacent sheathed conductor. Of course, this method would mean me de-sheathing the CPC!
I’m an electrician here in Australia, we’ve had the earth conductor insulated for 40 years ! . And our conductors are all multi strand not solid .
This is why I love Doncaster cables they are the number one cable company around now
Thank you
Are they?
@@acelectricalsecurity yes
@@kobirelf97 well the last time I used their cable when it was exclusive to cef, it was like chewing gum, and get to the end of the drum and the last several metres was useless, because it was all twisted and deformed.
Will there be a 3 core version of this too
Meanwhile in Europe, everyone has been using round cables with all conductors individually sleeved since even before the € became a thing you could touch.
yea and flat cables have been banned long time ago too
@@marcviej.5635 That's not actually true, you can still use flat cables (NYIF) but their use is discouraged and limited, must for example not be used in bathrooms and must be completely by plaster anywhere else.
@@babooXXThat's possible where you are but here in Belgium flat cables won't pass inspection
Why are round cables better?
@@edc1569 That's mainly just preference; there's some minor technical advantages: round cables are easier to drum (you don't need to care about the orientation), and it's easier to drill a round hole and use a round grommet to clamp a round cable for tension relief than to find a way to do so with a twin'n'earth.
One advantage of not having an insulated CPC is that is dissuades people from using it as a live conductor; I've found a fully insulated earth core used as a neutral in a 4-core cable on a three phase supply - if insulated CPCs become the norm I would put money on them appearing in 2-way switch circuits as a cost-cutting exercise.
Australia has been using twin + earth for years with a green and yellow insulated earth for 30 years plus.
👍🏻👍🏻
I did think it was bare because if there was any cut in the lines it touches earth first making it safer. Worse case live cable sleeve damaged , it now has an added protection from touching earth first .
My house here in Australia was built in the late 80's and the TPS cable used has the earth already insulated lol. Having said that, we still haven't managed to invent double glazed windows over here yet
Or spiders that don't kill you.
🇨🇦 here - how much does a spool of 2.5mil 2-core+CPC cable cost on average from a wholesaler?
If only I could have had this in the 80s!
When will this be available from main suppliers, My main supply is CEF
Hi, This type of cable has been available in Thailand for a number of years now
A weird experience for somebody from Germany where to my understanding cables with uninsulated earth wire are legal but I have not even once seen that.
Here in N America we are not required to sheath the ground (earth) conductor (what a PITA!) so I can see why everyone is so exited about this product.
In the USA we don’t sleeve our grounding conductors. And our plugs are easy to shock yourself if you remove from the box. We doing ok😊
All this and we're still installing ring circuits.
🤦🏻♂️👍🏻
I always thought it was because CPC is a safety circuit trip, so if Live or Neutral get damaged it would activate the CPC Earth easier. .. With a green/yellow sheath, the damage would have to get through two layers of sheath to activate the safety feature.
Delicious! Finally...
Doncaster cable has alwayas been my first choice
Interesting, earth conductors is a smaler size compared to L/N in the UK?
it is because the protective device will engage and if not it will just get hot of it is in use
Yep
Yes, they're not normally current carrying so they don't need to be as big - only big enough to not get too hot during the relatively short duration of a fault to earth before the fuse blows or breaker trips or etc.
Theoreticaly in nearly all failures the main RCD will trip before the earth conductor gets "overloaded".
Our code here (Belgium) requires the earth to be equal or more.
Will they be doing it in LSF?
Australia has had twin and earth with the earth shielded in green and yellow for decades

from the states, I'm a bit amused by the effort put into making sure the new style of cable is the exact same profile as previous iterations, because our cabling changes size and profile frequently. in my career, it's gone from big and bulky, to slim, and now it is getting bulkier again.
I'm guessing the UK being a smaller market makes it harder to justify the tooling costs to change things. The thing that's got me confused is why they feel the need to sleeve and identify ground. Apparently they don't really care about it being insulated (after all, they aren't even calling it insulated). And I'm not actually sure why you would WANT ground insulated - if a wire has come loose and is rattling around the box, it having a chance to touch ground and trip the breaker seems like a good thing to me. And it's not like people in the US have a hard time identifying the ground wires - they're always the bare or green ones.
@ccoder4953 i can understand sleeving the ground on a 240v system. It protects from accidental contact if the wires haven't come loose, and uk boxes aren't as roomy as us boxes. It's the fact their fittings are made to such close tolerances that is different. Exposed weather tight fittings, i can see, but our fittings for stuff inside the wall have huge tolerances.
AT Last it’s been in nz and Ozzie for donkeys years and at last we getting up withe times 😊
A year ago you made a joke based on Irish cables. Now Earthsure is on the market. I wish this would be real next year as well.
As do we 👍🏻
Why has this not been done before !
This type of cable is used in Australia for many years.
