Sure trip if you switch on all the sametime, and your water heater run at max.

Do you on all at the same time everyday? You need to know what is your usage pattern. The power hunger are #4,#10,#8, #1

To be precise, 1,2,3,5,6(25biji),7.
If the rest on but two heater don't use I will have 30A standby right ?

Add on: who can tell me how many kW this specs consumes ? Assume on at lowest temp

Calculate based on hp->kw or follow the table there ?? Blur with the specs

It is a 2.5HP or 2,640W input. It state at the below electricity.

Follow the table if it got write down. That is actual of the power input.

The above 6.96 kW is what ?

It is a heat exchange capacity.

Based on this box, is it mean that there's two 63A?


Happen to me again now.
4 downright are on, 2 fridge, the rest all off,
Number 5 item tripped. What's happening here

It is a fuse holder with both Live and Neutral isolated. Should be just 1 fuse base on the diagram state.

The rcca trip is probably something short circuit. Isolated the point and check which 1 cause by it. Stop using it if you found it.

Today I just contacted the wiring man, I kena ejek by him. Cuz he was persuading me to use 3 phase due to I have 4 Aircond. He told me I have 2.5hp, 1.5hp, 2 x 1hp confirm must use 3 phase or else it will trip. So I calculate the power consumption to him and said its not even 60A how come will trip, he said it doesn't count that way, then kena ejek. So I wanna get confirmation with u guys, is he right or we(all forumers) are right?

If some where is shorted, not matter what phase you are using it will trip also.
Just to make your problem clear, did you check is which plug point causing the trip?

There are some spike when compressor switch on, but is very minimal. And when you encounter trip is all the Ac switched on?

You have to tell us more detail. If not we have hard time to understand your actual situation and just guessing only.

How does it trip? How long it happen? What is your pattern usage.

The rcca trip is not cause by overload. It main is to protect short circuit. A spoil electrical appliances that probably life threaten.

If your consumption is over, the sfu-63 inside the fuse will blow out. Leave you everytime need to change the fuse.

This are the mostly basic scenario will happening. There is still many cause which need you to tell in detail.

Hi sorry for confusion .
My meaning is that by what he told me, he meant that even if others not on and u have this 4 air conditioning on, it will be tripped. Even 2.5 + 1.5 will cause trip d, this is based on his experience. He said very hard to explain to me
For the short circuit wires, already sorted out which one is short circuited . Already block that switch from switching on d currently. I'm just asking is it the current is not calculated that way or that's not the way we count current?

3 phase Aircon like cassette 2.5hp and above, most use in banks.
Especially on York ceiling model

So now I understand is, the rccb trip is not cause by the aircon. But other thing that you already solve it and isolated it.

There is no trip and all your electrical applicance are running fine. Right ?

It is just you worry about the tripping or overload and you want to have a 3phase. Because the electrician advise too ?

What I don't understand is, if there is nothing happen since you have using for that long, what trigger you to think to have 3phase? Are you going to have more electrical applicance?

The basically calculation is correct. Of course there is more advance electrical calculation that probably will get you

I have seen 5hp or more in residential.

So the correct method is to connect direct to DB? Does it involves hacking the walls? Planning to install aircond points in 2 rooms.

Yes, better to connect to a separate breaker.
You need to pull new wire, but wall hacking can be minimise if you use expose conduit.

Any idea how much will it be? But if buy aircond the installer will not create plugpoint connecting to the DB right?

Don't know how much. No need plug point, just a switch.

It won't trip. if you check the outside tnb fuse sometimes it rated 100 A. more than the demand that u have right now.

total hp u have 6hp. it is not even close to 30Amp
