Well, all I can see is, there are 3 fuse or something like that..
And it has three rows of those jumper-like switch..

I see no wires.. maybe it's concealed beneath the wall or something.

I don't know. I want to be SURE. I want no hassle if all the air-conds are switched on at the same time.

Should be correct since only the 3 phases carry fuses and not the ground.

Ooops, I made a mistake.

It has 3 of this thing:-
[attachmentid=234391]
Each on a row..

So is it 3 phase?

mmm I wonder, is it compulsory to use three poles circuit breakers on 3 phase?

kons: from the picture, looks like it's a 2 pole circuit breaker...

That's the circuit breaker lah, my house has atleast 60 in panel. You'll have to check your meter and the wires going in and the distribution mechanism

Bro, can elaborate more abit, how to check whether it's 3 phase?

What about the wires going into the Distribution Box? Does it give a hint if it's 3 phase or not?

Confusing. I'll take pic when I'm free. Oh well.

3 phase systems should have 3 wires going into the meter, one for each phase, coloured red, blue and yellow.

kons: ya take a photo

Aha ok thanks. So I'm guessing we got to add a new wire from the meter to distribution box for it to work?

that's a single phase RCCB...residual current circuit breakers. they work like an ELCB and cut off the power when there is electricity leakage. 3-phase RCCB's exist, wonder why your electrician decided to give u 3 units of single phase.

The one that the empire23 has are MCB's minature circuit breakers. They will cut the power when there is an overload. They are like a replacement for fuses.

To figure out whether you're on single phase or 3 phases, look at the TNB meter. Single phase got 2 wires going in, 2 wires out. Three phase has 4 wires in, 4 wires out.
