Tip for Corey. Once you have drilled pilot holes in mini C.U. offer it up to partner enclosure (3 phase box) and mark the hole position through existing pilot hole. Perfect alignment without messing around to find centre of circle.

[@gajnjaca]

That "black paint" is probably hidro insulation of the exterior wall, drilling that low risks compromising the insulation and bridging the water or humidity entry to the house

[@mikescott58]

Hi guys, Yankie viewer here. I love the channel. Electricity/electronics have fascinated me for as long as I cn remember. You were wondering about how the 110V worked. Here in North America (US specificlly) our mains for residential service is 220 V, singls-phase, though, in relity nominally more like 240 V. Unlike there, neutral is not referenced to either leg, but rather a center tap. This gives us 120 V from one leg to neutrl for most things like lighting, plug sockets, and small appliances. Larger items like air conditioners, cookers, elecctric dryers (and, of course, EV chargers) connect across both live leads for 240V. Earth is typically bonded to neutral at the main panel (consumer unit) and to the cold water supply where it enters the building. Also our plug sokets are typically fused at 15 A and 20 A for kicchen appliances. Probably a good thing I grew up here rather than there given the number of times I have gotten shocked, 240V / 32A probably would have killed me. :-)

I enquired about getting 3ph to the house for running workshop machines. But the DNO told me that only 2 phases came down the street, with properties alternating between those 2 phases. To add 3ph they would have to run a custom feed from the substation. VFD's on the machines was cheaper!

[@benjaminc1816]

I’m having a new build house built at the minute (due to move in around August time) and managed to get a 3 phase supply fitted as an extra (it cost me £1200 but well worth it in my opinion) - there will be a 3 Phase DB in the garage for machine tools / 22kw car charger and L3 will run from that to the house and feed a standard Hager Consumer Unit - thought it best to upgrade and future proof - so for anyone else looking at new builds, it’s well worth asking as its a lot cheaper then doing retrospectively (although they didn’t have a clue what it was asking for until i drew them an electrical plan and spoke to their electrical contractors ) - I’m baffled to why that house has a US 110v split phase system though - are they an American family who didn’t want to replace all their appliances? If so then the fitting of the 110v points must have cost more then replacing the appliances.

[@dennybaker8755]

Thats very expensive . . . Hope its made of gold 😂

[@havoctrousers]

There isn't a scenario where those 110V points make any sense to me. Shipping appliances to the UK would be stupidly expensive, never mind setting up a dedicated 120V board, transformer and accessories. There are very few appliances that would need exact US supply characteristics, the only things I can think of being motors where the AC frequency is used for the functionality (clocks, tape decks, VHS recorders and turntables) and you could just buy 50Hz UK versions. They must need that 120V/60Hz for *something* ? Maybe as part of the building's previous purpose they had a lot of US visitors with their own devices?

[@patdbean]

@@dennybaker8755 I would think the cost of a 3 phase service basically comes down to the distance from the 3 phase main to the service head and how much trenching is needed.

Nice new intro guys! This mystery 110 install has everyone talking.

[@cumberland1234]

I don’t think the 120v will be centre tapped earth as the RCBOs only look to be single pole, I wonder if transformer is a frequency converter too as it looks expensive!

[@xNYCMarc]

In the US and Canada (since we are on the same grid with each other), the electrical system is 240 volt with a center tapped transformer. The neutral is center tapped and bonded to earth. Neutral to one of the hots will give 120 volts. Hot to hot without the neutral will give 240 volts.

[@nmccw3245]

Yes, that looks more complex than a simple step down transformer. I bet it’s a rectifier / inverter delivering 110V 60Hz or even center tapped 220V.

I have domestic 3-phase and a little known implication is not all energy suppliers have 3-phase SMETS meters (e.g. OVO - badgered me into a smart meter and when the technician turned up to fit the meter he said "Oh it's 3-phase we don't do that!" I said that I told the person booking the "upgrade" so they ended up giving me £30 for having wasted my time). Not yet a problem but the time will come when you can save money with smart-based tarrifs.

[@hithere2546]

A three phase is actually 'normal' here in the netherlands, but they usually dont go above 35 amps, but with loadbalancing you can also place a 22kw.

[@hithere2546]

For info 3 phase here is also 230/400v

[@benjaminc1816]

In the US, the 110v is a centre tapped 220v supply - centre is earth referenced neutral and each live is 110v to neutral - their bigger appliances (dryers / HVAC etc) uses 220v as it feeds from both lives, and the generic appliances just use 110v - benefit is if you touch one live then the worst you’ll get is 110v through you - but the downsides are they need thicker cables as amperage is higher for the same wattage appliances on 240v - they have less protection in the board RCBO’s / AFDDs etc - but at least they don’t know the excruciating agony of standing on a UK 3 pin plug when walking through the house to go for a piss in the dark 😂

Hey we do not have 220 volt power in the US. We have 120 volts, 240 volts and 208 volts... In the US most houses have single phase L1, L2 Neutral and Ground. L1 or L2 to Neutral = 120 volt service and L1 to L2 = 240 volt service. Most major appliances in the US like Air Conditioners, Ovens, Clothes Dryers and Hot Water Tanks are 240 volts.

[@kenrohde6841]

@@michaelholliday100 Roughly, UK nominal voltage was 240v but was changed to 230v to harmonise with Europe which was at 220v nominal. Actual voltage will be in quite a range. In the UK, the declared voltage and tolerance for an electricity supply is 230 volts -6%, +10%. This gives an allowed voltage range of 216.2 volts to 253.0 volts (so the former 240v nominal is still within the normal range, that is also reason it is only -6% as the lower bound is the same one as when the declared voltage as 220).

@@kenrohde6841 "Roughly, UK nominal voltage was 240v but was changed to 230v to harmonise with Europe" -- except it was not actually changed, the UK supply voltage is still 240 V same as it was before. There was no need to change it as 240 V lies quite well within the 230 V + 10% range.

@@waqasahmed939they’ll become more common as electrical demands evolve. I went ahead with an upgrade and its proven to be extremely worthwhile now whilst undoubtedly a good future-proofing measure. The key for me is being able to charge 2 cars simultaneously at 11kW each, within a time limited off-peak charging window. More cars will support 22kW in the future. I currently have one (iX M60) and although its a rare requirement its been very handy to be able to charge it that quickly on my own drive.

[@effervescence5664]

Interestingly when I first enquired with Anderson you can apparently fit the 22kw changer on single phase and it will work due to being the same charger. It's just the connector and out going lead which is different. A good option for homes that can be upgraded to 3 phase but already have a set date for delivery before hand etc. It's also the charger recommended by the Porsche dealers for the Taycan.

[@havoctrousers]

I've fitted the Schneider EVLink ones and they're the same. They don't have a tethered lead so you can use the 3P lead that came with your car for single or three phase. Ultimately, all these EVSE devices are really doing is using a contactor to link the incoming lines to the pins in your type 2 charging connector (the 3 horizontal middle pins of the type 2 connector are L1-L3) and the car is doing all the work of AC->DC. The EVSE doesn't really care whether just L1 or L1-L3 are connected although it will have an internal CT on each line for metering. Like you said, if the tethered lead is only 1P (cheaper and less copper) then it needs changing.

[@effervescence5664]

@@havoctrousers Oh I just meant from the pov that some manufacturers aren't actually using the same internals across the 1p/3p versions, either different contactors or actually no terminals for the extra phases. Not fitted the Schneider, we tend to fit the Zappi and Anderson as the main 2 with Hypervolt becoming popular mainly due to Jordan's channel here. I have a feeling that once the world stops being in such chaos all chargers will just be supplied 3 phase compatible as standard, especially as they're considering making all current homes where possible 3 phase to help with the transition to renewable - whether that comes to pass or not we'll see.

Most modern homes in the Netherlands have three phase power (230/400 Vac). The main breakers are 25 or 50 Amp. When charging an EV with e.g. a 90 kWh battery, at night, with 22 kW from 35 to 85% SOC, that takes 2 to 2.5 hours. So it's ready before you go to bed. A bit over the top don't you think?

Could also be in a US military type area. I’m assuming the giant transformer since it looks more than just a transformer is doing frequency shifting as well as voltage dropping because it look fancy. Did not know that there was a whole line of US sockets in the UK style complete with permanent installed wiring that is crazy got to know more.

@@imark7777777 The US equipment would be 60 Cycles while Great Britain is 50 Cycles. You can split the power, but you cannot change the hertz of the power. You will destroy appliances with motors especially compressors. This is because, when you run an appliance like a fridge compressor motor on a slower cycle than what it has been designed for (60 Hz frequency vs 50Hz), it will cause the electric motor turn slower. This inevitably results in an increased strain on the motor windings, causing the compressor to burn out.

[@jensschroder8214]

22kW are rare even in Germany. The electricity supplier has to approve it. 11kW are often installed because there are subsidies up to this size and the electricity supplier only needs to be informed. The problem is only when the car wants to draw 32 amps on one phase and is limited to 16 amps because of 11kW. Then it makes more sense to install a 7 kW charger one phase with 32 amps. Or trying to get 22kW approved because that's 3x 32 amps.

[@mikebosman9280]

Here in Denmark it is very normal to see 3x25A in a house. In our small house we have 3x35A.

[@thomas.6497]

Perhaps to add some info here. In Ger a typical (house) setup is 3 phases with 63 amps each. The first fuse (3) are also 63 amps. Then the next device in the path is a Selective Switch Breaker (SSB) (I do not know how you call it in English) followed by the meter. The SSB is typically 63 amps as well under normal operation (no car charger and no PV system -> so-called intermittent operation). Then come the distribution with RCD’s (usually type A) and breakers (usually B16). So installing a 3P car charger is normally pretty straight forward. Usually you just need to add another RCD (type A) and 3P breaker. The DC 6mA residual current monitoring is usually embedded in the charger. When a car charger (and / or PV system) is installed the house operation changes to so-called duration operation and the SBB has to be changed to 50 or 35 amps depending on the meter wiring.

1:52 not to start a comment war, however the US outlets are upside down. While there are arguments either way, the majority of manufactures assume the ground pin is down, because that is the way all the cabling are made for the transfers and other times (charges etc). Kind of like if you guys put the ground pin down, but its our assumption here. Our larger 240V style plugs assume ground pin is up as all 90 degree cables are made that way here. 😁👍

[@CoolerQ]

It is commonly done both ways. I wouldn't say ground up is wrong. Residential is most commonly ground down and commercial is most commonly ground up. The usual argument is that commercial installations tend to use metal faceplates, and if the face plate becomes loose you'd rather have it fall on the ground pin than a live pin. Of course that's only a problem because our plugs don't have sleeved pins.

[@dg2908]

These US outlets on a UK sized plate are part of MK's logic plus range which curve in at the top. They definitely intended them to be fitted with the ground pin at the top as in the video

[@matthewdale956]

Us switches are upside as well 😉

[@HenryLoenwind]

I'd argue that ground-down is the safer configuration. When the plug rattles free, the bigger gap will be at the top, so having the harmless pin there to be exposed to touch is nicer. (Really, who thought designing a plug in a way that a live pin can be exposed to touch was a good idea?)

[@RB-lt8kt]

Always check your car maximum AC charging input as a lot of cars will only charge at 11kW max on AC. Installing a 22 kW charger could be an expensive mistake. As a Ford dealer in Cardiff found out by installing 22 kW chargers instead of DC chargers against the advice of the installers and complained why his Ford Mach E cars weren't charging at 22 kW. Perhaps the issue was the Mach E only has a 11 kw charger ? LMAO.

I'm in UK and as I have my supply looped from next door on 80amps. I asked my DNO to swap too 100 amp fuse and they said I can upgrade to 3 phase at the same time as they have to dig up the garden to run new cables..might as well put in 3 phase right??

[@Saaj2]

Yes definitely. Since it's a looped supply I'm guessing it's free of charge? 100% do it! You don't necessarily need to get a 3 phase meter until you're ready.

[@danjenkins88]

Updating to 3phase isn’t always extortionate - I’ve been quoted 3k inc vat from the DNO (which is still a lot considering I have a telegraph pole at the end of my 10m driveway) - I was surprised when I got the formal quote!

[@stuinNorway]

If you have a pole at the bottom of yout garden you're lucky. We needed to upgrade as our home had a 1 ph 50A circuit, had to dig 25m up the road, plus 20m under our block paved drive, and a totally new intake box, secondary distribution box to split to car charger, and then into house with rest... It was NOT cheap, just the cabling to the house was over £10k

[@chapman9230]

Just got a quote and yes we are lucky too. Pole directly outside. 2.6 k but we have to dig a trench.

[@sstorholm]

Rather fun that up here in the Nordics the smallest supply for a house is 3x25A, with no option for single phase anymore. I think most DNOs won’t do single phase except for technical applications, like a supply for an ISP network cabinet or something.

[@arnoldsmit3289]

Same in the Netherlands most common is 3X25A, and in older homes and apartments 1X35A.

[@grahamnicholson1553]

Why are external small cabinets always being used to house RCD protections on your installs? In Australia we would have put in something like the Hager BD163T and kept the RCD on the board. I have been meaning to ask for a long time as it seems common in your Car Charger installs to have a separate RCBO and Breaker rather than combining on the board and with single pole it is even simpler.

[@nectafarious8842]

I have a pole with 3 phase in my garden. I dug my own trench to the house from the pole and the MEB ran a cable into a new 3 phase/pme head in my utility room (I needed 3 phase for my garage and workshop). It cost me £350....30 years ago.... Looks like I got lucky and future proofed my gaff!

Wow, that's exactly the meter we have. Power companies have wanted to change the meter for a smart one several times but each time the guy has come out he has gone away again not knowing how. We have L1 and L2 into the meter with L3 not connected. L1 then feeds the main house consumer unit and L2 feeds a unit in the garden (via a secondary rotary meter). We don't own the house (church rectory) otherwise I would be inclined to get this all sorted out.

[@billccn]

Will be rather expensive to create a charger that takes 91A (22kW/240V) through a single phase though. Remember the "charger" on the wall is really just a smart switch, the car itself does all the AC/DC conversion. If most cars won't take it, then there will be no market for such chargers.

[@HenryLoenwind]

@@billccn Strike that "most". It just isn't possible to get more than 32A of a single phase to a car with a Type2 connector. There's only N/L1/L2/L3 (plus PE and 2 data lines) in the plug and each of those contact maxes out at 32A. Putting L2 and L3 on the same phase as L1 would overload N---the only reason there's not N1/N2/N3 needed is because of the phase-shift of the phases. In theory you could do L-L1/N-N/L-L2/N-L3, but that would need some very, very good communication between car and wall box to make sure neither switches to that configuration if there's anything else connected. (Not impossible, Tesla does exactly that for DC charging in pre-CCS2 models...)

[@Mladjasmilic]

Fun fact: You can do 10A 7.2kW over 5x1.5mm² cable (total 7.5mm² of copper). Fot the same power, at 30A, you would need at least 3x4mm² (total 12mm²), which is 50% more copper for the same power.

Not sure it's worth the bother currently as my kona only accepts 11kw 3 phase. Not sure there's an aftermarket for upgrading that to 22 to be honest.

How can you avoid the 3 phase upgrade in the future? eBoilers to replace old type of gas combi boilers require 3phase supply and I cannot see any other alternative. Gas Combi Boilers are the most common heaters in the uk and no way you can put heat pumps every where.

If your house only has single phase then where did you get the 3 phase supply from? Did it already have 3 phase but you were only using a single phase? I know the LA charge more than 150 quid to add 3 phase as it requires running new cables,digging up the road to the nearest 3 phase supply.

In the UK it doesn’t always correlate that just because the labels state the rating of the service head that the actual fuses fitted match that given rating, it can often be downrated depending to what is practically required. It wouldn’t surprise me if this service head could have 80a fuses installed or even 60a depending on the size of the installation when the installation survey was carried out.

The US is daft. The craziest one is the high leg idea. You get 240v phase to phase on three phase and 120v phase 1 or 3 to neutral. But they also have that high leg nonsense with 208v from phase 2 to neutral. Delta transformer on the secondary with a centre tap between L1 and L3 to get a neutral. Then the new voltages are 277v phase to neutral or 480v phase to phase, but I doubt that is for domestic yet.
