KolaShangOne:
4mm Is widely used for cooker.. I think it can handle it, right?

Yes it will , and these days people don't use electric cooker for long cooking like that because of power consumption

Ibk2020:
Pls who can explain how we can pre-install kitchen heat extractor ventilator pipe?

No videos on YouTube for this

Extractor fan or cooker hood ?

If it is kitchen extractor fan, there different sizes but the common one for tye kitchen is 6inch or 9inch
Procedure ;
-If you are installing 6inch, get a short piece of 6incj PVC,
-Bury it to the wall facing the outside or fence to allow the extracting the heat outside.
-Let your electrician run a conduit to the pipe for electrical connection, you can allow the extractor running if your light is on by looping it to the nearest point if light or create a separate a gang switch to control it .
-After screening you can now I stall your extractor fan.

Same procedure for 9inch but instead of using 6inch pipe , you will get a carpenter to make square box of 300mmx300mm
Then follow the other procedure above

Let us be part of your project from begining.

He said he’s using 2.5mm for socket ,AC,cooker,water heater

And that the load will be direct and the circuit will be 30Amps and it’s standing on its own sir.

And also he said that it is Full conduit pipe that’s being laid there that’s the reason the cable are much sir.

The electrician is not getting it right .

Protecting an appliance with 32A with wrong size of cable...hmmm each cable has their own current carrying capacity and each breaker has their own protective current as well

Using 30A to protect AC it means if there is fault current somewhere and your breaker suppose to trip off, it won't and the next thing is to melt the cable since the breaker refuse to trip.

Don't allow road side electrician to give you wrong information . The rating of circuit breaker(MCB) or starblock as normally called by this road side technicians for each of the appliances are as follow:
-10A MCB is for lighting
-20A MCB is for AC(direct from DB to AC switch)
-20A MCB is water heater (direct from DB to water heater switch)
-30A MCB or 32A MCB is for socket( you can loop 5 or 6 socket to one MCB
-32A/45A MCB is for cooker control unit.

bayo2018:
He said Coleman brand sir
I’m thinking of cutix because I read here that it’s the best cable to use
And he said 2.5mm for the AC.

If you are in East cutix is okay . 2.5mm cable for AC? IEE standard says 4mm. Below are the recommended cable sizes for appliance by IEE regulation

1.5mm is lighting lighting
2.5mm is for socket
4mm is for AC and water heater
6mm is for cooker

Hello everyone, what to do if a pipe suddenly bursts and it leaks heavily? After all, while the plumber arrives, the apartment can be completely flooded.

Try to lock all the valves to prevent inflow of water to the building
