THAT'S NOT A CONSUMER UNIT - 3 PHASE POWER FOR NEW BUILD HOMES
This consumer unit is enormous compared to the unit usually installed within UK homes. This is a house with a difference. It's the first major housing development to be supplied with three-phase power as part of the Western Power Distribution (WPD) low carbon technology strategy.
This two-bedroom house is being kitted out with low carbon technologies that we expect to be commonplace as we move away from gas heating. In this video, we explore the first fix electrical installation for PV, battery storage, ground source heat pumps and EV charger.

hi sir im your big fan ang electrical engineering graduate i dont have job please help me
Will you have to pay three standing charges though?
sort out the volume too low
I am ax retired electrician. Amazed how standards have changed. Been out of it for many years now. Very impressed with what I saw of the installation in a new property. Was only yesterday when I heard about 20kw high current charging. This I felt was going you cause a major demand situation. By coincidence I have found you today carrying out a 3 phase supply to a basic home. 60amp S Phase in my time max. glad to see this has been addressed for new homes. Wish I was still young. When I started my apprenticeship, I found myself removing gas. lighting to wire out homes for the first time. That was in Margate Kent. Contractor still going today. Thanks for the video.
Jings, one could buy a whole wee house in Merthyr Tydfil for just the cost of that distribution board and AFDDs.
It’s so good to see young guys presenting their work. Shows their is hope in future generations to continue building and improving infrastructure rather than just maintaining.
Whenever I saw British consumer units I was always amazed that relatively big loads like water heaters for showers and hobs were single phase only, using thick wire and breakers with 40 or 50 amps. I am used to having 3 phase in every house for ages, the breakers being 10 to 16 amps max. Flats were often single phase only with a 35 amp main fuse, if heating and hot water ran on gas. If you had electric heat or hot water, 3 phase has been common since the 1960s. Even reduces wiring costs. If you can feed a hob with 5x2.5mm² wire (400V 16A) vs. 3x6mm² (230V 40A) that's almost 1/3 less copper needed.
One day we may catch up!
Where are you?
Germany... 3 phase is really common around here, I think also in France, Austria and Switzerland. Don't know about other countries for sure. Single phase supply is still used in some houses in rural areas or in flats, although the building will have a 3 phase service which is split for the single flats. 3 phase motors in non-commercial environments are not really a thing, except for maybe sewer pumps or lifts in larger building complexes, but being able to split large loads on 3 phases is quite nice!
@@efixx Well, everything is working fine, no need to rush :-) Just keep the nice 1363 plugs!
@@moffarocka3537 There's no reason why Hobs can't be wired up for 3 phase considering most of them now come with 5x 2.5 flex manufacturer supplied attached, so if the property had a facility for it.
Impressive stuff, kudos to the DNO and housing developer for being forward-thinking
People thinking a domestic with full 3 phase is overkill is being stupid. Electric shower on with the hob on can be nearly 80 amps alone , before heaters or car chargers .I did my house upgrade to 3 phase. Not only do I now have a future proof house. I have the ability to use 3 phase motors , fantastic for the home workshop.
👋 do you get three standing charges on your bill or is it a cumulative cost?
@@HughEdwards it's 1 charge . Guess it may vary from providers .
How much did it cost for the upgrade from single phase to 3 phase?
@@Ily2361 £2200 for them to dig up a bit of the road, and do the cutout. I did the digging on my land , it lowered the cost.
Standard in the WPD area for new builds
Really useful information - even as a non-electrician! we're about to build a replacement dwelling and trying to get to the bottom of electrical & heating needs - Western power have indeed coincidently just upgraded us to 3 phase without asking!
Thanks very much once again. Really informative! Found the data cabling for the heating etc interesting. Working on a house presently with a smart heating system (nowhere near as complicated as yours) but I was interested to see what was in yours. Plenty to think about as usual!
3 phase for domestic has been normal in Denmark for 50+ years. We only have 13 and 16 amp fuses. The hob run on 3x16A on a 2.5mm2 cable. The rest of the house on 13A fuses and 1.5mm2 cables
Absolutely agree with this. This is what limits the size of roof mounted PV. Supply balance is critically important.
A lovely smart job guys. Never done fibre optic before . I can see some future update corses being needed if I’m going to keep up to date with the latest tech .
Great video guys, thanks for sharing.
This is great, can’t come fast enough for me 👏🏼
I'm impressed. Might have to move back to Wales just for this. Now if I can set up my woodworking shop in the garage I've got somewhere to plug in my cabinet saw.
That was my thought 3 phase for the garage, although wouldn't want a 2 bed semi
From the previous video someone said it’s over kill! Nope just as the chap saying system is balanced, products using more power than normal eg chargers will be split and balanced. Think it’s a fantastic idea. For years thought 3phase would be a great idea in domestic properties, as we have installed heat pumps and EV chargers this would of had a massive benefit. Great videos again guys keep up the great work.
The future (hopefully)
The silly thing is back when GEC Nightstor boilers were first envisioned 3 phase domestic supplies were going to be the norm. Then natural gas became super cheap and took over instead but even now those GEC Nightstor boilers that are out there are as cheap to run as natural gas, that's 50 year old electric heating technology. Unfortunately we're in a capitalist society so progress goes where ever the money can be made and legislation happens afterwards rather than it being the other way round.
in reality its only gonna be balanced if your using nothin but 3 phase loads. its all marketing wank. 99% of your loads are still single phase, its completely random as to which loads you are gonna use the majority of the time, so nothin at all changes really. i guarantee you measur L1-L2 2-3 1-3, your loads are def not gonna be balanced, not to mention, is a friggin house, your not gonna be pulling more than 20-30 amps at any given time, an thats if its summer n u got ur ac blastin at that. 100% this is a hustle, and a waste of money.
@@trope5105 surly having 3ph charger, 3phase heating/AC units will be balanced between. Making sure sockets feeding large white goods are on different phases?! Then things on your ring circuits are not going to cause any problem same with lighting as it’s such low consumption. I think it’s a good idea.
@@Beariam24 well im definietly not gonna spend the money to do this, specially when balancing 3 phase loads is not a big deal what so ever in this setting. not to mention im for sure not gonna waste my money on a 3 phase unit when a single phase one is a quarter the price for the same amount of power n work output
Can see the whole estate level networking and management being a pain in 10 years time, if working at all. Fine for a municipal building, shared boilers etc but if it were my house I'd want the data systems to be standalone.
They built a new supermarket near me in the early 1980s. Entire room heating was via heat pumps taking heat from local air. Since the latest refit with new inefficient aisle fridges, they've had to fit gas fire heating to the fridge aisle to keep the customers warm. The Technibel heat pump system was decommissioned decades ago. So now the gas heating system heats the fridges which pump the heat out of the building to the plant room where it's heating the air outside.
Well I'm glad when we moved the electric supply from the cellar in the house to the new garage I built 30 years ago, that I had them put 3 phase in instead of single phase. Now we are looking to sell and downsize it looks like it may be a selling point. And it only cost 70 quid to have it moved 30 years ago.
Yes seventy quid wow. Back then they took into account the increased amount of leccy you would be buying. Now the DNOs also have to make a profit.
I could only imagine this being useful in large houses, in an instance where a single board isn’t sufficient and you have many high current loads, fantastic! 3 phase for all! I could imagine the balancing load situation could be tampered with by DIY Dave’s in the future though...
As a long time retired electrician, I keep suggesting to my son to retrain as an electrician. He is currently a landline phone/data network engineer. With our reliance on electricity ever increasing it is the way to go.
As we saw in the video, most of the larger electrical appliances (heat pumps, inverters, batteries, EV Chargers) also require a data connection these days, so an electrician that is also comfortable wiring high speed data networks should be in demand, whereas "phone lines" are on their way out.
Excellent idea bring it
Damn you could go sledging in that panel enclosure! Amazing stuff its crazy to think that we have ended up here from timber framed 3036 units in a relatively short space of time when you look at the bigger picture. The network would be RS485 protocol surely? RS45 is a conversion adapter I think. Well anyhow better than 232 on a serial!
7:40 - a dedicated utility network connection - no thanks. Wow, Big Brother is definitely watching you here!
Gents, this really is interesting, thank you. Personally I see this as the future. Kudos to Western Power as a DNO for providing a TP&N supply and also Influencing customers to 'De-carbonise'! How innovative. Not just ahead but leading the way! I have no issue with the audio, sounds okay to me but I did struggle a bit with the accents (apologies from London) Did Kian of WPD say he was working with Zero or Sero - what do they do? Also, what did Dan say he was doing the Sero or sound controls? Did Gordon say coook? Lol. Please clarify the reference to a 'shoebox'. Looks like there is loads of opportunity for good Sparks going forward. Looking forward to Part 3 on the site as an energy asset to WPD.
Thanks - Zero is the English translation of the welsh Sero - Sero are the energy services partner for the project.
Great stuff boys!
Thanks
Super interesting! I'm in New Zealand and have an old house built in 1953 and the supply is annoyingly split in two, 32a to the night rate meter and 32a to the day rate meter. I want to put solar in and a second heat pump for the second living area and get rid of the gas fire, plus I have an EV that will chug down 32a on it's own. will need a three phase supply for that me thinks!
As an adult learner currently doing my lvl 3 (8202) this is something that is a really exciting change, I'd really like to be employed by an installer who carried out this kind of work or the DNO
Get in to any DNO or IDNO doing anything to get your foot in the door. Great places to work and so much more interesting.
@@coster1983 ive applied 3 times now, not giving up, whats IDNO ?
You HAVE to laugh! Only 50 years behind much of Europe ... Germany especially! Well I suppose it's good that it's FINALLY coming! Thank God for EVs!

As a rally fan, my reponse would have been ... "At what kind of speed and was he ditch hooking to do it?" 😂😂😂
Re the SPDs in the DB, what is the risk assessment for the type 2 SPDs you refer to? The CRL / risk assessment of 443.5 only applies to transient overvoltages of atmospheric origin, hence type 1 SPDs, so which/what risk assessment are you referring to regarding switching overvoltages requiring type 2 SPDs?
Love those hats 😂 oh and think I'm glad I'm retiring in a couple of years
Looks like there’s a 4 core SWA going from the suppliers meter to the big DB on the inside of the house. Presuming the SWA is longer than 3m, doesn’t this need a FUSED TP&N isolator?
Many electric ovens and hobs sold for the European market actually come with the option to connect as 3 phase already, so depending on the equipment being installed, balancing the load might be fairly easy if this kind of supply becomes more common.
Obviously they have had three phase for years
@@robertsmith9836 The UK is really out on a limb with respect to the rest of Europe.
Are they actually fitting 3 phase smart meters? Trying to get an upgrade on an existing 3 phase install depends very much on provider as the installer has to have additional training.
This all looks great, but considering most house bashing sparks struggle to wire a normal consumer unit nicely, I predict These boxes will hide some right horrible installs!
I would like to have the wiring diagram for that large panel discussed while looking at the actual parts. I would have learned a lot more.
3-phase or not, 100a or 200a, in the USA they have decent sized CUs. Ours in the Uk have always baffled me. Spending so much time cramming all the wires in to a box the size of a bit of A4 - or slightly bigger. This is the hub of all your house electrics. It deserves a decent space in your home. “Oh but UK houses are much smaller than USA ones....” - no, I don’t buy that as an excuse. When I rewired my house I terminated all the runs to a separate 2 row large DIN box with lots of space. Then ran wires to standard CU - I did this only to be “compliant” and to stop the next spark moaning at me. Or if we sold the house. Sunday Rant over 😁
you're not wrong. we have rules about how big a box you have to have to accommodate the number of things that will be going in it. and even an under 700 square foot cottage, here, is likely to have at least 20 poles worth of circuits, with every appliance getting its very own.
I’ve been an US electrician for 20years now in the northeast. Our older panels and meters are smaller too. They started gaining size while I was training up. We used to joke about the new meter size saying, we could fit a family of three in them. Aside from these 3phase units, it does look like your panels are gaining size too. Which is good for workability and safety. But just imagine the mess you see in your panels, at times, being all over a 42” long 14-1/4” wide 200amp North American panel…like a plate of spaghetti!
8:08 Just beautiful!
Some electric ovens that are made for both the UK and Europe markets have got different wiring options that configure them for single phase or three phase mode of operation, as well as dip switches that control the maximum current that can be drawn over that single phase. Sometimes the only difference is the UK manual only explains how to wire them up for a single phase!
Great insight we’ll check that out 👍
Ranges are typically connected to three phases (3 x 16 A) in Finland but a single phase (20-25 A) is also an option as not every apartment necessarily get three phases. In Sweden they actually have 400 V ones that require three phases.
Interesting! We are going for more and more TP boards in bigger houses, even connecting ovens in TP to balance. Bit confused how the phase swapping at meter will go in the long run. I can see why they’re doing it, but managing circuits inside seems more sensible to us… How are they terminating the SWA in the meter cabinet? Can’t see a TPN switch fuse going in there!
Basically they are going TP but then they're a little to shy to go all the way. I'm from Germany and my single family home has a main distribution board that makes the one presented in the video look trivial plus two more and all including the meter are TP. SP is dying over here, more or less.
Rather than phase swapping, I'd prefer to see each house equipped with three-phase to single-phase UPS for critical loads (e.g. lights, smoke alarms, heating circulation pumps) and a phase converter for non-critical loads - net result is the network is always balanced.
1:40 that hole cover the being used as a drip catcher hehe
Add 30cm to the width and you have roughly the standard sitze for German houses in the last decades 😉 Happy to see that the UK electricians don’t have to fiddle around anymore in those very small units (at least in some new homes) 🙂
Now you have single RDCs do you agree it would be better to use 10ma not 30ma have to had any discussion about 10 20 and 30ma RCDs?
I’m just buying an off-plan new build due to be completed summer 2022 and have requested a 3-Phase supply from the house builder (northern power grid is the DNO) - I’m hoping it’s approved as it’s the future! Especially with heatpumps / EV’s / AC etc. The UK is so behind continental Europe with our shoddy single phase supplies / ring mains etc! It should be the standard in new 3+ bed homes in my opinion. Good work western power!
Good lucky - let us know how you get on!
I know about phase rotation and I know that to balance the load we can wire the phases different but still keep the rotation in the correct order. My question is that I haven't heard a simple term for it. Any help.
So do you move house after 7-10 years when all the tech starts to break down? Or is there a service charge or insurance that you put down against it?
Just to add to this. I'm in an existing 1950s council house and Western Power/National Grid as they are known now, installed a 3 phase supply when removing a looped supply. WPD/National Grid were fantastic getting this installed but getting a 3 phase domestic meter on the other hand from British Gas has been nothing short of a nightmare so the entire house is still on 1 phase at the moment.
Please do more on rotating phases, I'm sure many guys are installing multiple EV points and not rotating phases.
How far was the meter box to the consumer unit? Sparkies seem to want to installed an extra fused box separate to the meter box. And when it 3 phase thats a big box
Why is the final finish on everything on this build so poor? Great technology, installed shoddily. First fix looks good, fiishing is crap,
That’s painters not electricians
@@efixx completely. Plastering and painting atrocious for a new build.
Newbuilds regularly have dual RCD type AC boards even today. No developer is going to pay for this stuff and compliance will be unchecked.
Great video 😎
Wow interesting, you guys are so behind the times, here in Australia our houses have had 3 phase power for over 50 years.
What are you thoughts about having 415v in a domestic house.
Very interesting. Noted that the EV Charger had a cover fitted upside down below it where the cabke went into the wall near the beginning! Gas is on the way out for new builds, it'd be interesting to know what the ongoing service charges will be to maintain the estate network/services? Good to see 3 phase, a shame more suppliers aren't doing it to future proof their areas.

@@efixx thanks
About time we have three phases. We can have those large dryers and washers we always use in laundraumats and can also have an EV super charger 😍
The Americans manage large driers with 240V single phase (albeit in that odd 120-0-120 format). In any event, the problem with putting large driers into UK homes is not the power required. I doubt any use anything like as much as an electric shower, but the space to install them.
Is the ev charge 3phase outside or still single phase on that install or can you run 3 single phase chargers at the one property
It’s a 3 phase charger - you could in theory have 3 x single phase
Im a new electrician living in Finland. But im pretty sure 3 phase supply has been used for ages here already. (20+years) Usually all gadgets over 6 kW are 3 phased. 3x 10amp 230v. Or 3x 16amp 230v. Regular homes dont have bigger fuses than 16amps. Only the main fuses are usually 25amps
Great info - What about the Sauna
@@efixx sauna ovens are usually 6-11kW. So 3x10amp 230v or 3x16amp 230v. There are no RCDs protecting sauna oven circuits though.
What did they use to gland the 4c 25mm into inside the metering box to use the armourings as a earth ?
Would there be two fiber data connections to each property or is it shared network for estate and personal connections are sent on the same cable "multimode" .
It’s a private network for the energy services. Home users has a regular open reach line
the sound is low can you fix it. Thanks
Hello, i was wondering what youd recommended on a consumer unit that is somewhat futureproof. I heard three phase is really expensive to retrofit. I was looking to install solar, thermal battery, infrared heating, battery and ev charger in the future. Thanks for any help.
Worth biting the bullet and doing it now, single phase is limited to 80A or 100A in certain conditions. A 32A car charger is a good sized chunk of that. The other option is to load manage everything but you could end up with longer charge times or reduced heat output from HP.
How feasible would it be for everyone in the average street to retrofit 3 phase?
Good
@eFIXX guys some questions. Is this a bespoke TP+N panel from Wyler not available to purchase or have you come across similar panels which all the addition of extra din rails for metering and affd’s? Also what is the purple data cable, you didn’t say what it was - is this cat 5 or 6 ? It looked like it had twisted pairs but would be good to clarify? When you brought the CPC through, was there any mechanical protection?
Sorry iPad autocorrect is a pain - “ Wylex” and “with the”
Hi Gary, do you have any details on the consumer unit. Looks ideal for one of my Customer projects. Kind regards Robin
It's not obvious to me how this better balances the VNO network compared to rolling the phases at the property level. However, I can see the advantage of providing three phase to the household in terms of the amount of power that can be provided. However, it introduces a lot more complexity in the household wiring. Also, some of the techniques that car charges use to avoid overloading the incoming supply by monitoring the current consumption through a single phase and de-rating accordingly, are not going to be as simple, or maybe the thinking is that it won't matter given the huge amount of power that could be delivered. In any event, that's a lot of space taken up in the properties. Fine in those larger houses, but not so much in a one or two bedroom property.
Can't hear what anyone is saying!!! I've got everything at max volume, and it's soooo quiet. EDIT: I'm on my main PC now and I can hear with my 150W speakers connected to my 350W crown amp at max volume!!! Not my amp or speakers sadly:(
Same here, sack the mic guy...
Same here. I can't hear fuck all. This could all be done in the editing stage. Not the first time either. Unsubbed.
1:38 - the perfect way to funnel the water into the hole. and into the property..! LOL
I know it is a small thing - but should they not have put in a larger DNO box on the outside of the house?
I would be interested in seeing how someone is going to terminate that 4 core 25mm swa into that main switch, because I can't see them getting a TP&N switch fuse in that meter box.
That's the first thing I noticed looking at that meter box. The sparky on this job is going to have a nightmare sorting that out.
In one of the videos they ranted on about not installing any other switch gear in the meter box.🙉
Why? Don't you think 25mm cable can cope with a 100A fuse without having an identical fuse next to it?
@@MrRorz12 yeah I seen that, I can't believe that the amount of effort that went in designing those installs that they missed installing a second box for the switch fuse, it's a struggle with only a switch fuse in on a 25mm swa, I know I have just done one, and it was only easy because I made the switch off and pulled the slack back
@@markrainford1219 oh the cable can cope, no problem there, but where's the switch fuse going to go?
How is the SWA terminated in the meter box ? Doesn't look enough room for a SW fuse
Normal incomer in Central Europe usually we fuse them in 50 or 63 amp
How’s anyone supposed to fuse the tails on a 4 core cable in that enclosure?
Is their a difference in price of having a 3 phase electric meter installed per day or is it same sort of charge per unit as a single phase meter? Also do you need a specific commercial supplier instead of the domestic ones like octopus energy?
Asked about 3-phase when gutting and rebuilding current 1930s semi. Advised not to bother. All me reasoning has proved valid. Wish I'd insisted
The smart home tech is great, but look at some of the 2nd fix & decorating on that installation, it's horrible! Paint all over data cables, plaster gaps under switches and boxes... I wouldn't be happy as a homeowner there.
Do I need 3 phase for a 1200 sq. Ft. House? Only big frig, dryer, well pump and solar
A bit more volume on the video would be nice, thanks! Apologies if this is not the type of question you expect.
I've fitted quite a lot of their meters.its an impressive estate to be honest.
Thanks for the feedback 👍🏻
Great opportunities for sparks ⚡️
On the money 💰
0:17 lovely condition for a brand new property...!
Very nice super like
0:23 Nice application of mortar on the windows there...!
This smart stuff is all very impressive, but if something fails in that secret control box in a few years time who's going to be able to fix it? Will the original installer do it, but what if they've gone out of business by then? I assume form the secrecy that it's not an 'off the shelf' item...
No secrets... we use loxone
No way they'll admit it but companies are still "hotrodding" their heat pumps and storage batteries to work together on areas I've worked in. Only way to get them maintained is from the original installer and manufacturers. Supposed 10 year guarantee on hot water batteries which fail after 3 and cost 3k to renew with no serviceable parts. No issue with 3 phase going to homes but homeowners need to prepare for big bills on all these technologies. Personally, I'd go storage heaters over this lot of white elephants.
Do you think Screwfix will do one of those three phase boards on the cheap BG branded 🐔
Give it a couple of years and the DIY brigade will be in the wholesalers asking for them 😂😂
It will be a steal at 2 grand a piece populated.
In my state in Australia - we have been insisting on 3-phase supplies to houses for about 8 years now. It allows for 20kW of solar per household - and will allow for charging.
All that sun ☀️ 👍
Which state? Currently in SA the limit is 5kw per phase without special approvals
@@johnschroeder3072 You need 3-Phase and your approval is almost automatic.
@@tcpnetworks That doesn't make sense in regards to my comment. I mentioned per phase which would imply that it could go up to 15kw on a 3 phase system which is not 20kw.
QLD stipulates a max of 6.6KW system for a domestic install.
Sorry for the potentially daft question as I'm not a spark but I have heard some people say putting more than 1 phase in a domestic means you are bringing in over 400v instead of 230v, which can be potentially more dangerous although they the odds of making contact with both phases at once are quite low. Are there really extra safety concerns for people with 3 phase installed?
Each phase is 230V, you just get three of them. But you get to also connect up 400V big ticket items like a heat pump and a super charger for your EV.
@@JamesNeave1978 Apologies I just realised how badly worded my question was, I get the bit about x3 230v phases & across any 2 phases you can get around 400v, so the potentially the risk of a 400v shock exists within your house via damaged wiring etc, (or so I've been told) but I wondered just how likely it is or if there are specific precautions taken in the instal to mitigate against it etc?
@@northeastcorals We have lots of very tight building and electrical regs to ensure that our stuff is as safe as it is possible to be. Both in installation and not getting damaged over time. Including testing extreme circumstances like flooding and fire. And test intervals to ensure nothing goes wrong. And then they account for extreme circumstances such as nobody bothers to do regular testing. Just... Don't ask me what the specs are _called_ (I just know they exist 😂) I suppose the only bit I know about are those AFCIs they mentioned. If they detect at least 30ma of current leaking from live to ground, that's you getting electrocuted, they cut the power. Multiply redundant system too, in case something fails. Our obsession with safety is something to be proud of! ☕🧐👍
Still common here in Australia to see 3 phase going into larger houses to run airconditioning etc
Loving this series guys, western powers offering free upgrades to 3ph?
Whats the brand and model number of the distribution board/consumer unit please?
Would the standing charge daily rate be the same, given the homes will offer better balancing for the DNO?
Daily charges are set by the supply company not the DNO, granted a small portion of this goes to the DNO but not as much as you think.
More info on how the system works in this new video - kzhead.info/sun/otJ9p6uCbF-ZrGw/bejne.html
In Norway we have supplied 3 phase to all the houses for years now already. Think it is more common to have 3 phase than 2 phase nowadays.
Ideal if your an engineer / mechanic. industrial lathe or 4 poster ramp in your tiny garage ? If this is classed as industrial electronics can any tom dick or harry play with it without and domestic sparks qualifications ?
Well,I watched it end to end ...and unless I blinked I didn't see how the 4x25 SWA was finished off in the meter box
We will be covering that in a future video
What you failed to mention is that western power will bring 3 phase to your meter cabinet but you can then still use single phase for the home. We are building highly insulated homes that are supplied by WP. 3 phase and 300amp is definitely excessive for one house. We have all electric houses and have had diversification analysis done and reduced our demand considerably. No heat pumps no electric showers. People forget that the costs to supply a large site are huge if you want that much demand on the grid. I do all our utility contracts for our sites and some of the prices we were getting for the connections are outrageous until we prove that our demands are lower. Down from 1000kva to 350kva for the transformer on one job.
Yes you can of course still opt to use single phase.
Would interesting to know more about how they are balancing over the whole estate.
Gary did mention that they rotate the phases in the various cut outs to overcome the convention of always putting lighting on L1 etc. However, I was thinking similar to you and then thought wouldn't it be good if there was some form of monitoring and changeover so they could actually move the loads and balance the estate network if a certain phase was being overloaded? I guess the trouble with that would be that any three phase equipment would change direction. There must be a feasible solution to this somewhere though..
@@jollyfinequality9865 that's kind of the line I was thinking of, it must be the knowen loads the sparks are using in the first instance? Hence why you need a massive board.
Many rural French properties have always been served by three phase, although it's more likely to be 20 amps per phase!
Very useful for me - thanks !! I am about to embark on a self-build with a load of solar, heat pump and 3-phase. My DNO is SSEN, but not heard great things about them and domestic 3-ph installs. Anyone here had any experience with them?
We would love to come and see your project
@@efixx I will message you through your website contact
Why do you even need the DNO?
@@Swwils because the DNO are the people who control the power network, and would be the ones who install the 3-phase cabling & metering to the premises.
@@CoolSteve08not enough solar and storage to go off grid then.
Just had a quotation from WPD for my own house which is an upgrade from single phase to 3 phase @ £3000.00 does not include digging the trench on my property.
Are you installing a heat pump etc
@@efixx not at the moment. I wanted to be ready for vehicle charging (1 van & 1 car), but at that price, i’ll just put the ducting in ready, at this point.
If it’s associated with low carbon stuff and we think it includes EV it should be foc
@@efixx really?! Wow ok. That gives me the information to email WPD back in that case and see if they’re do it for free. It’s a really simple job for them as the drive is dug up, ducting is already in (most of), all they are doing is digging the pavement up, disconnecting old service, reconnecting new, running in new cable (in my ducting), and fitting a 3 phase header in the outside box that i’m collecting from central stores and fitting for them.
Let us know how you get on
