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.
See the completed installation 👉 • THE FUTURE OF HOME ENE...
This is installation is part of the Parc Eirin project by POBL Homes. Energy Services provided by the Sero Group.

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.

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.

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!

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.

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.

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.

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.

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 😁

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!

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?

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.

@bibo159
@bibo159 2 роки тому
The meter does not actively switch phases, The method they are talking about is called a "phase roll" so the first property is connected left to right as such; L1, L2 and L3, The next property is connected left to right as L3, L1 and L2. a third property is connected L2, L3 then L1. so the three phases are being "rolled" one place to the right each time... This ensures the three phase is still rotating in the same direction but the lines can be balanced amongst these properties that have identical internal wiring.

@@markhardacre1 I think you are getting confused between Delta and Star three phase systems in addition to single phase, without going too far down a rabbit hole, 'Most' Low voltage mains supplies are in a three phase star configuration. This means they have a neutral conductor, This only conducts the imbalance current between line conductors. so no the system does not need to be balanced at all. However imbalance causes massive inefficiencies and even voltage problems upstream due the delta configured of high voltage feeding circuits. (delta does not have a neutral so cannot dissipate imbalanced currents, therefore the voltage is effected due to complex electrical principles.) The consumer unit they showed in this video is three phase, However some of the final circuits are single phase meaning they only require one phase, a neutral and protective conductor(Earth/CPC or whatever the IET want to call it next so they can sell a new flavour of the 7671)

Interesting experiment! That board is definitely overkill for a 2 bed semi. It’s great to have space for future upgrades, but a 2 bed semi is never going to need this much extra. Surely a standard 3ph commercial DB would suffice at less than half the size. Also the extra metering in the board is presumably only there for them to gather data on this prototype estate and wouldn’t be installed on a wider scale?

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.

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..

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.
