Welcome Tanzania

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@@MrZenzio European Sockets are outdated and unsafe.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

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

Is het niet zo dat de nul gewoon wordt door verbonden door het automaat?(behalve bij de aardlek)

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.

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)

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.

Glad you enjoyed, videos more regular now!

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

Dear Paul sir thank you for making my learning efficient....;)

Glad you liked it!

A lower fuse rating would be advisable. This will keep the device or appliance protected.

@@rayc1503 Thanks 👍

Good idea

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.

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.

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

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*

US houses typically have 240 volts @ 200A service, which allows for a maximum of 48,000 W of power to be drawn.

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.

In the US it's recommend that they connect in the main service panel, but nowhere else.

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.

Seen our new incredibly detailed MCB video? link: kzfaq.info/get/bejne/ndd1qJylna7bh2Q.html

Sir, maybe you can make another video about this👆🏻. Thanks again.

Seen our new incredibly detailed MCB video? link: kzfaq.info/get/bejne/ndd1qJylna7bh2Q.html

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..

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..

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)

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: kzfaq.info/get/bejne/ndd1qJylna7bh2Q.html

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

@@EngineeringMindset I will check it out, thanks for link!

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. I know I am better off than most US citizen having 3 phase 230v at my house, but man did I wish I had 400v. Big machinery gets cheaper and cable cores sizes shrinks ...
