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.

@ruan2587 2 жыл бұрын

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.

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.

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.

The meter doesn't have any fuse, and we have two meters. One was provided electricity authority meter that measures how much power that you used and cost you it is located outside the property another call "Ranee meter " that located inside the property near main distribution board use monitor real time voltage, power, PF , current and also the KWh that reminded you to save energy and save electrical bill

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.

@EngineeringMindset 2 жыл бұрын

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.

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)

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.

Please explain about the current rating of mcbs

@sandervesik173 Жыл бұрын

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.

@asystole_ 2 жыл бұрын

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.

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!

@alanboro 2 жыл бұрын

@@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

So is a RCD just a ARC fault or something else completely?

@markkennard861 2 жыл бұрын

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..

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.

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 ...

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.

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.
