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.

You had me laughing as I watched the earth sleeve drop and thought, 'Yep, been there, just a few times' 😏😎🖖

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.

Finally the UK has caught up with Republic of Ireland! The hours of sleeving you're going to save!

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!

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. The Globe Collector, Tasmania.

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

New in UK. In Germany since 50 Years.

Brilliant idea. The comment about dropping the sleeving is so true- usually when I've been on a stepladder.

We have had this in 🇮🇪 for years with the exception the CPC is the same size as the other conductors.

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.

As an Apprentice Electrician working at a cable manaufacturing plant (not doncaster) love seeing these videos.

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 👌🏼👌🏼🙌🏼🙌🏼

Very exciting for our industry 👏🏼

Thanks Gary you have score us all a winner and Doncaster cables trying to take all the glory. 😁

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 👍

What a revolution. Good to see you pommies are finally catching up. Australia introduced this back in the late 70's.😂😂

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.

What a time to be alive.

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

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😂

I thought in Belgium things went slow . We have this for decades ! 😉

Incredible! Australia went to multi strand twin and earth with individual insulation on each conductor 50 years ago. Which makes the UK 1/2 century behind us.

When I saw this in my feed, I thought it was dejavu!!! I was trying to work out if Valetines day was also April fools!

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).

Well done guys again, masters at work. Well done on keeping same price, that is amazing.

Even as a DIYer this is exciting! 😍

Great Stuff !!!

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)

Glad to see it made in Britain!

That's brilliant

Everybody in the UK will be speccing this immediately :) What a great idea :)

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.

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.

About time too. I'll be buying this.

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..

Awesome product

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!! ❤

wow tbh a small but quite pleasant change to ffs I've drop the sleeve. again !!

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 🤔

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.

Very nice, must get some.

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.

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?

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.

Brilliant well done

Absolutely cracking

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.

Game changer 💪👍

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

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.

Great idea, if it's the same price and quality, this should be used as standard!

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

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!

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"! 😀

Are you going to do a low smoke version?

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

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

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..

Doncaster cable has alwayas been my first choice

If only I could have had this in the 80s!

Nice idea, but one small disadvantage, if you pull the bare earth wire hard, it simply cuts thru the outer insulation, helping stripping time.

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.

Nice to see that the new pre-sleeved will cost the same 🙌

Interesting, earth conductors is a smaler size compared to L/N in the UK?

a very good idea 😊

Why is the ground conductor thinner in UK? It should be at least the size of the phase/neutral

Will there be a 3 core version of this too

Can this cable be used alongside the Quickwire T connectors?

When will this be available from main suppliers, My main supply is CEF

My only question now is does it work with the quickwore junction boxes you feautred before? 🤔

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.

Thanks for adding actual captions for the Deaf

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 .

Wonder if the new quickwire connectors are affected with this?

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.

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.

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.

So you're just starting to catch-up to Australia and New Zealand? Good job...

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 !!

Will they be doing it in LSF?

No more sleeving falling of second fixing a spotlight🙌🏻

This is why I love Doncaster cables they are the number one cable company around now

🇨🇦 here - how much does a spool of 2.5mil 2-core+CPC cable cost on average from a wholesaler?

Delicious! Finally...

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.

Australia has been using twin + earth for years with a green and yellow insulated earth for 30 years plus.

As marine Electro Tech, all our cable comes with sheathed earth. Never understood why domestic stuff doesn’t 😂

about time

Hi, This type of cable has been available in Thailand for a number of years now

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. 😮

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.

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.

Meanwhile in Europe, everyone has been using round cables with all conductors individually sleeved since even before the € became a thing you could touch.

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 .

Wait is the news that you have all three in a cable now? Was that not a thing over there in England already?

Would these still work with Quickwire?

As a DIYer I LOVE this! The new yellow and green colours are soooo pretty, and they've also change the red and black to new fancy colout too, so cool! Definitely going to toolstation tomorrow to get some for the full rewire im doing for my neighbour.

We did never really use unsheathed earth in the first place here in germany, but good to see the brits got around to using sheathed earth too, lol.

Just puts the price up even more no doubt
