How to Electrical Working autocrat Programming..!!!
plz Share With me your Autocad Animation video Link.???
Welcome Tanzania
Having passed my electrical qualification over 30 years ago I wish I could go back and show myself this video. Things would have been easier 😂
Great video once again. I really love the way you put things across in a simple manner. 👍
This might be a small thing, but I appreciate that you used proper European sockets.
I would have thought using a safer outlet would be better.
@@annoyingbstard9407 I have no clue about such things; I just liked seeing a socket I recognized; unlike the American sockets I'm used to seeing in illustrations.
@@annoyingbstard9407 safer outlet, explain please ?
@@MrZenzio European Sockets are outdated and unsafe. Definitely not “proper”
@@scottwhitley3392 european sockets and regulations in general are from the safest in the whole world. I live in Switzerland and we have the safest regulations in Europe
Wired up my garden room, open consumer unit found a spare breaker, then shoved the earth and neutral into nearest vacant terminals and nada! Your explanation of RCDs enabled me to realise my CU was split in two with just one RCD and the other half was on breakers alone and I'd wired the live from breakers and the neutral was on the RCD neutral block. Quick re jig balanced the supply and bingo! Thanks so much
Your videos are incredible in one morning i have learnt more than i did during school
Excellent video, especially liked the animation showing how the RCD detects ground faults.
While I knew that the RCD "detects a difference between the active and neutral', I struggled visualising exactly how it works.
But now, thanks to you, it's very clear!
Thank you!
Man, I teach English to future electricians, this is extremely helpful! More, please 📚🙏🏻
Interesting. I had not heard of a "consumer unit". In the States, we just call it the meter and the breaker box along with sub panels.
US version video going live on Tuesday
In the Maldives, we use the terms as used here except that we call main switch, MCB, and the rest of the individual switches, circuit breakers.
And in Australia we call it a switchboard.
@@lukeday87 that is what we used to call what telephone operators would use.
It's funny you call it "meter"... I think "footer" or "incher" are more appropriate names for US
could you also do a video like this for 3 phase european consumer units?
If you want what we have in Norway then a 3 phase European would not do. We have for the most part 3 phase IT net, our brothers in Europe for the most part has 3 phase TN net.
@@Mr.Engineer. i have always been corious as how they look inside but i cant open mine as it is not allowed here in Norway, my consumer unit is 3 phase TN i belive
@@norwegiannationalist7678 But what do you do when the breaker trips? (Do you really have to call someone to reset it :O)
@@mart43 no of course not i just flip the breaker, its not like in austalia where you have to get a electrician to replace bulbs
@@norwegiannationalist7678 Everything is basically the same except that you have a RCD that takes 3 phases instead of 1 and the buzzbar is separated into L1, L2 and L3. (Separated inside the plastic cover.) So if you look @6:00 then the first breaker would be L1 (Br) second would be L2 (Bl) and third would be L3 (Gy). This is in Sweden thou. Not quite sure about the UK also it only applies of you have the micro breaker and not the diazed/screw breakers. (Don't know the name for it in English)
Hope that answers it in part.
Interesting to see how residential panels work in different countries.
Here in the Netherlands its required to use breakers with both phase and neutral, also 3 phase connections are more common.
Is het niet zo dat de nul gewoon wordt door verbonden door het automaat?(behalve bij de aardlek)
Perfect video!
Clear and concise explanation of UK power distribution.
The phase to neutral ERROR will trip the circuit. The BIG QUESTION is if the earth
conductor is ONLY CONNECTED to earth, will it TRULY trip the circuit?
Thank you.
It will. Mainly because the main high voltage transformer is also grounded via a earth conductor.
@@Ter_ror Thank you for replying. Understand what you say, the main high transformer
is ALSO connected to the earth, thereby completing the circuit. STILL, would like
to see a demonstration to see this ACTUALLY functions. Thank you again.
The neutral point of transformer you receiving power from is grounded to earth, so if you only have the earth rod without a bonded neutral earth at your mainpanel, you create a TT earthing system which has a fault loop impedance of about 20ohm through the physical earth back to the transformer where the neutral is bonded to the earth. So with any fault current to earth at your home, and the fault loop impedance being so high, the fault current flowing through earth to the transformer will end up being so little there is a big chance your breaker will not trip. Earthing configurations are extremely important and neutral earth bonding for example the TN-C-S.
@@ruan2587 Thank you for replying. (Good chance your breaker will not trip)
Thank you guy for your work. It's very interesting to learn new things. Greetings from Kazakhstan.
You are simply the best!
Excellent, the building block approach is perfect especially as you start from scratch up to populating with mcbs.
I liked the explanation of how rcbs are wired.
The video is 👍👍👍
Will be trawling through your vids to find other gems and I'm only to happy to subscribe.
Nice one! Once again concise, informative and very useful
Glad you enjoyed, videos more regular now!
This is really good content .I learn lot of from this video . We call this consumer unit MDB board In Bangladesh.
Thanks for your video.And give more and more interesting video 💕
Interesting, but here in Norway we've made a complete mess out of that system with our IT-net :P
Great video. Here is South Africa, lights and stoves are not wired through the RCD(we call it an earth leakage), so the live conductor go straight to the MCB from the mains breaker to the load, with the neutral conductor coming back from the load also going straight back to the neautral bar on the top left and then to the mains neutral. Just another way of doing it because sometimes lights and stoves can cause false tripping, hence bypassing the earth leakage.
It used to be that way here in the UK too. My house (circa 2006) has an RCD on the electric shower and plug socket circuits but none of the other circuits.

Here in Brazil, this type of connection (master MCB followed by master RCD) is permitted only if the master RCD rated current capacity is equal or higher than the master MCB.
Seen our new incredibly detailed MCB video? link: ruclips.net/video/gqEu9t8HwW0/видео.html
Very interesting and nicely explained.. thank you
Great video. The one thing that I think could have been a little bit clearer is the point that the reason we have MCBs is to protect the wiring in the house from being overloaded, causing heating and potential fire.
Yes. The wires are only rated for a certain load. Residential wire codes state a certain amp rated wire is to be used. Also when wires are spliced the contact becomes less and can make them heat up, drawing more amps
New and useful information

I had wondered how Euro circuit breaker boxes were wired. Thanks!
In Europe we usually have 3phases in homes and new installations (atleast in Austria) require (some exceptions) a cable with 3 phases and PEN (Protective Earth and Neutral combined) The PEN then gets split up into PE and N.
The majority or Europe and the majority of the world even, uses a single phase. Germany and Austria use 3 phase to residential properties and I'd imagine with electric cars becoming wide spread we might start to see 3 phase connections more common place across the rest of the world
@@EngineeringMindset also in the Netherlands, Belgium, Denmark, Luxembourg, and some more European countries you see 3fase for residential buildings.
@@EngineeringMindset I have also made some 3phase "residential" (dont have too much information about where they actually go) fuse and Circuit breaker cabbinets. They are 60amp installs with 30 or even 5mA RCBs and they are specified for 380V 400V or some other weird 3phase voltage I currently cant remember. They are following housing installation specifications thus I think they are for that use. I know they are going out to India the US and Asia. Dont have further information nor can I provide more company information for...hopefully obvious reasons but I think they are less common for single family homes
@@EngineeringMindset probably never in cities where it's the norm to stay in apartment complexes such as in Singapore and Hong Kong. we prob would just live thru life never seeing one of those ever... unless electrician for big appliances like the EV changer "Rig"/ setup.
very well explained and presented video, subscribed :D.
Looking for some advice, I have 3 appliances each allegedly consuming 3050 at maximum capacity, but the wires and my main feed to the consumer unit is getting so hot. I deliberately upgraded my consumer unit so it could handle these appliances. I installed the outlet (Specifically for these appliances) using Prysmian 10mm2 twin and earth, wired to a 50-amp breaker, then installed ANOTHER Prysmian 10mm2 twin and earth, wired to a another 50-amp breaker so there are now 2, one for two lower end of the consumer unit and the other for the higher end. Furthermore, I also have two BG 80A 30mA 2 Residual current device (RCD) installed on the consumer unit and the main feed that powers the consumer unit has a fuse of 100amps.
These appliances are in a container where I linked each outlet to one another so they can draw power from the first one (again, each has its own 50-amp breaker at the opposing side of the consumer unit, one for the upper side and one for the lower side), not sure if that is causing resistance as I even have the powercables with 13amp fuses to power those appliances, but since there is a 50amp breaker for each outlet, I’m still confused.
What are your thoughts on putting RCD's in series to add redundancy? in case one is faulty, or degrades.
Hi, Could you do a video on how electricity flows from the substation to feeder pillar to street lighting in three-phase electricity
The main fuse is there to mainly limit how much power you can draw from the power network not because it's protecting your property tho it does protect the circuit up to the fuses.
In NZ and Australia the main supply neutral is never interrupted. Supply Neutral is hard wired to main earth. This is called the MEN point or multiple earth neutral. Ring subcircuits are also illegal here. Mark the spark.
cant believe how much this simplified things for me lol
please also make video with SURGE PROTECTION DEVICE WIRING and 3 Phase also
Fantastic
Slightly different in the Netherlands, use MCB'S which switch the neutral line as well.
My wiring scheme is brown for live
Blue for neutral and yellow-green for earth.
That's the old colour code. The new is brown, black, Ash and blue (neutral)
Ik...
That's the new colour code now
@@danielteyehuago1633 is witch country is that code used because here in Europe we use Brown, blue, yellow/green, and black for switching and signal. or black and grey together with brown for 3fase
Phase*
I noticed the horizontal configuration of the electrical panel. Curious about this I did an actual photo image search for such panels in the UK and discovered this to be accurate. Any reason for this design spec? I am in the US so this was new to me.
So in commercial panels, which are typically 3 phase, they are vertical but single phase residential panels are horizontal. They're roughly the same width as a the US panel, but just more compact. I don't know why it's designed horizontal, it's pretty much always been that way in the UK. Something that springs to mind is that because heat rises, the heat of the lower circuit breakers will rise and warm the upper breakers, slightly reducing their limits in a vertical configuration. Although its not really an issue that's going to cause significant problems.
@@NIAtoolkit in the UK the regulations state that you aren’t allowed to use different manufacturer’s parts in the same panel as they’re not tested against one another and could have unforeseen reactions to one another i.e electro magnetic etc..
It may be indicative of the relative power usage in the US vs UK that the main fuse in the UK is typically 100a, which at 220 v allows for 22000 watts of power, whereas, in the US, a 400a panel at 110v or 44000 watts might seriously be a candidate for an upgrade to a higher amperage panel.
US houses typically have 240 volts @ 200A service, which allows for a maximum of 48,000 W of power to be drawn.
Thanks.
Awesome video. I'm only 14 but after watching this video I'm going to do a complete re wire of my nans house
You will opening a can of whip ass... most countries only alloy registered electricians as its prescribed electrical work. You could work in conjunction with a electrical worker if he is willing to sign off. Do an apprenticeship.. you won't regret it.
is this a residential split-phase system used in the UK? Or is this a simplified three-phase industrial panel? Looks different (but similar principles) to anything I've seen in any house, but looks similar (in appearance only) to stuff I see at work in industrial/institutional facility.
This is a common modern setup for a residential CU, with RCDs protecting a couple of sets of MCBs.
It is a single phase connection, used in domestic properties across most of the world except North America and some parts of Europe
This may be a long shot, but could this same illustration be done with a 3 phase consumer unit?? as I never understand that. that would be of masssssive value! Thank you
i want to ask. it is recommended if the earth wire connected with ground rod also connected with neutral wire of the service cable?
In the US it's recommend that they connect in the main service panel, but nowhere else.
Can I have Earthing terminal connected to Ground Rod and Service Head's Neutral at the same time? Is there any drawback or potential danger?
Do fuseboards need to be ventilated or can they be fitted in rooms that have a container ambient temperature of around 27-30 degrees?
Maybe I missed something, but I thought UK and EU used delta-connected circuits for power distribution, meaning no neutral is required. So where is the "neutral" for the house coming from? Another phase, or grounded at the pole?
In North America all modern power distribution is Y (star) connected, so the neutral is inherent to the system already.
great
Sir, can you explain in detail the operation of main switch, rcd, & mcb? How & when the overload & electromagnetic works? And how they affected by direct & indirect lightning strike? Thank you...
Sir, maybe you can make another video about this👆🏻. Thanks again.

Please I'll need an explan on how to go.
Thanks a million
In Belgium, Germany and the Netherlands it is rare to see the neutral come together before the MCB and RCD I would say never. They always go through the MCB
In Sweden the neutral either to a neutral block and then to a rcd or straight to a rcd and the ground is always straight to the ground block (this is with tn-s)

Stay safe.
Retired (werk'n)keyboard super tech. Wear your safety glasses.
I'm glad that I live and work in Denmark as an electrician, our system compared to UK / US is far superior, and more safe and easier to troubleshoot on :) Any videon on the Scandinavian systems? Denmark Norway and Sweden is almost the same, Norway use IT systems more because they live on a rock but other then that its almost the same, and what's up with only 1p not 3p? Is it that rare to have 3p power in a normal household in the UK?
Yeah, most UK properties and most of the world actually doesn't have 3 phase connection to residential properties. North America and parts of Brazil use split phase. We don't really need it, although load balancing would be better if we did
@@EngineeringMindset was searching for a map to show who had 1p or 3p at normal houses but couldn't find one. Not needing 3p power? What about charging my car, boiling eggs, ,making something in the oven, my welder, my bench grinder, my mill, my electric heater for the shop, I would say how can you live without it?
@@Novoo100 It certainly WOULD be useful (e.g. welder, grinder, big saws, vehicle recharging) in US and it is available, but not common and more expensive.
Do you mind elaborating a bit? What are "IT systems" in this context?
@@Novoo100 Cost is probably the main reason. With three phase you need three times the number of transformers and conductors as a single phase (although each conductor and transformer can be smaller). It's just less expensive to have a large amperage single phase for a residence that doesn't have more than a few kW of electrical demand. The vast majority of residences don't ever have as high of a peak load as you do.
Are most homes in Europe only rated for 100 A service? That seems a little low for today, especially since in the US we have 200A service.
IF any Argentine fellows are watching:
RCD = disyuntor
MCB = térmica
Do Argentines know what Earth is? I've had to install a jabalina (earthing rod) in my house. Come to think of it I've never seen an Argentina house with earth connection.... every house I've lived in, except for right now with the jabalina I've always had a tingling sensation touching certain parts of my notebook (doesn't happen overseas) and I've seen crazy things such as fridge freezers with cable that I'd be scared to run a 60W lightbulb on!
@@jimm9162 Good question. It is very common for countries in this region (and I'm guessing most of the 3rd world countries) to have old buildings without an earthing rod. That is because it was not standart practice at the time of construction and what's built it's built...
The law that makes it mandatory for any new construction to have an earthing rod is as new as 1972, so you can count that any building prior to that date does NOT have ground... and there are LOTS of buildings of that era.
Furthermore, in those buildings it is very common to see that the plug outlets are still of the old type E (just 2 rounded holes)... when we've been using the type I (3 diagonal lines) for the last 30 to 40 years.
So in short: any new building (and in Buenos Aires there has been a boom in construction) has a proper earth connection. that combined with the propers RCD's at the consumer unit makes it safe.
in any older buildings, it is essential for people to have RCD's... but I've seen old connections, in old buildings, without RCD's... and the old people living there often use extension chords and outlet splitters filled to the extreme.
This is why there is a saying in Argentina: never open the fridge bare-footed
Seen our new incredibly detailed MCB video? link: ruclips.net/video/gqEu9t8HwW0/видео.html
hmm, here I have a ground pin going into the concrete (I asume the concrete metal mesh is connected to earth pin(s?) into the ground, one connected to neutral, and I have 2 earth fault switches where it goes into... so basically ground is connected to everything. (I live in the EU, The Netherlands)
Please explain about the current rating of mcbs
The current rating is the current at which the MCB will trip. MCB are usually sized to match the cabling (and outlets) - lightning with 1.5mm2 cables would have a 10 amp fuse while 2.5mm2 wires would have a 16A MCB. This is to keep the wires from overheating. For smaller wires you would use even smaller mcb. However, if the connection is to an appliance or system using a known max amount of current in normal operation, you could size the MCB for the appliance instead, so MCB trips if there is a fault and overcurrent. MCB go down to as low as 1A, possibly less.

Hey, can you make a video tell that how important is the breaker? There is many house doesn't care the breaker, many even just nail a copper rod and weld into the breaker arm to keep the breaker not to break. (like my friends).I hope you make a video to tell how important is breaker.
We'll make a breaker video soon. But, depending on the electrical distribution system used, its an essential part as it protects the property from over current and short circuits. Other types protect against arc faults.
@@EngineeringMindset Thanks mate (You say "we"? Are "The Engineering Mindset" is a group/company?)
@@ammoniahuffers there's probably a team behind it... someone as writer/ storyboard, another as animator/ motion graphic artist, another as a fact verifier/ knowledge guru/ QA. it's prob harder to be a one man gang for this...
Without a breaker, a short circuit or overload is very likely to burn your house down. The excess current will cause the wiring in your walls to get extremely hot, easily igniting the wood/insulation next to them. All it takes is too many loads on a single socket circuit or a faulty appliance short-circuiting.
Seen our new incredibly detailed MCB video? link: ruclips.net/video/gqEu9t8HwW0/видео.html
Can you please do a video of Air Changes per Hour ?
if you have a hot and a neutral coming into the top main breaker for the unit how the heck does someone get dual voltage for things like ac/dryers etc. by the way youre explaining it, they only have 120 volts coming in
230v is used in Europe.
@@tougaardable off one leg?
Only north America uses dual voltage, the rest of the world basically only uses ~230V only. There are some exceptions of course. But US homes typically also take a 240V supply and split it into two at the pole mounted transformer to create two 120V out of phase from each other. But the UK, Europe etc all just use 230V to power everything.
@@EngineeringMindset holy shit you use 230 volts for phone chargers and stuff? That seems extremely excessive lol. So literally every plug in a European house is a dryer plug
Every plug is ~230V, not just in Europe but almost the entire world. It's nearly only the US and Canada that use 120V. Again, there are some exceptions. The plug will contain power electronics which simply convert 230V AC into 5V DC to charge our phones or increasingly there's a USB charger build into the wall socket. Most modern electronic devices can be plugged into either 120V or 240V, the power electronics figure it out and use whatever it's given. Check the manufacturer label on the device.
So is a RCD just a ARC fault or something else completely?
Rcd monitors the current in the phase vs the current in the neutral. If they are not balanced then it will trip as this would mean there is a fault to earth. Typically 30mA is all it takes to trip. We also have 230v standard outlet and 400v for 2 phase circuits. Twice the smoke and fire..
Could you do 3 phase IT net?
Are you in Norway?
That is correct, about the only country I think with a 3 phase It net without neutral wire. 3 phases and ground, but ground is only for safety, not to get sqrt3 of 230v'.
So 230v between the phases, would really like to have 400v TN net instead though even though we are more resistant to earth failure.
I only learnt recently that Norway still uses the IT system, didn't realise anywhere really used it still. Could be worth covering at some point, we have quite a few videos in production so it'll be after those.
Is IT net still used at hospitals and other infrastructure that is dependent on a failsafe backup system?
Yeah, a lot of Norway's distribution system is built for IT net as that have been the tradition for many centuries. I do not know why we ever adopted the IT net in the first place, but I do know that we early on had local power plants spread out near to industry that wasn't interconnected. I know one of these hydro power stations delivered 25hz to its consumers.
When the distribution network is drastically rebuilt or new distribution nodes being built it will always be 400v TN net.
