Can I get some advice from you about replacing electric cooktop? My outlet has black, white, and red wires, but my new cooktop has black, white and green wires. How should I match the color wires in that case? My wall outlet doesn't have ground wire at all. Thanks
OMG. In a 240 MEN system, NEVER bridge neutral and earth at an appliance or outlet. Never. If supply is protected by an RCD it’ll trip. If it’s supplied by an MCB or old style fuse and that appliance loses its neutral, the return current will be earthed making all metal on the appliance effectively live. It’ll kill you or at the very least, give you one hell of a belt.
Are you in Australia? Linking the neutral and earth inside your distribution board like in Australia is dangerous too. They should be connected before the mains enter your property to reduce the number of places where an open neutral can create this type of danger.
the wiring here is the same as our Omega oven and you can wire it either 3 phase or single phase, fast heating will not work on single phase. this is stated in the user manual.
Standard in former Yugoslavia was 3 phase but only 20 or 25A. You can use much thinner wires for same power, therefore save on copper. For example, for 9kW (3x230Vx13A) you can use 1.5mm wire, having 3x13A on phases, while neutral has no significant current though it if load is balanced. And in case of unbalance, neutral can not have more current than any of the phases. Total copper area is 5x1.5=7.5mm. For the same power (9kW, 40A at 230V) you would need on the single phase 6mm thick wire, which 3x6mm=18 mm, more than double.
Bad video, several mistakes: This is not actual 3 phase device, as it used only 2 phases. You have bridged neutral and ground, which can cause you cable to melt if you TT grounding (neutral grounded at the transformer, and you have local ground). Also any RCD would trip as there is current leakage between ground and neutral. You have used non heat resistant cable and if oven is used a lot, this cable can melt.

is it necessary to solder the wires?
No 😂
can you please show me inside wire
Mine Has RED wire I don't know where it goes

Where are you getting 3 phase into a house
Only get 230v single phase into home 🤔

There should be no bridge between Neutral and Protective Earth. This is not shown in the wiring picture.
running very fast and not clear video?

And he did not put ferrules on stranded wires (flexi).
Why the cheesy music instead of verbal explanation? 🙄
Because what he is doing is obvious
Need help. Anyone here?
